98 | When building support for a new host and/or target, much of the work you |
99 | need to do is handled by specifying configuration files; | |
100 | @pxref{Config,,Adding a New Configuration}. Further work can be | |
101 | divided into ``host-dependent'' (@pxref{Host,,Adding a New Host}) and | |
aeb62c7b | 102 | ``target-dependent'' (@pxref{Target,,Adding a New Target}). The |
97f3cb72 RP |
103 | following discussion is meant to explain the difference between hosts |
104 | and targets. | |
d98259f8 | 105 | |
97f3cb72 | 106 | @heading What is considered ``host-dependent'' versus ``target-dependent''? |
d98259f8 | 107 | |
b7becc8f RP |
108 | @dfn{Host} refers to attributes of the system where GDB runs. |
109 | @dfn{Target} refers to the system where the program being debugged | |
110 | executes. In most cases they are the same machine; unfortunately, that | |
111 | means you must add @emph{both} host and target support for new machines | |
112 | in this category. | |
113 | ||
8cc1c08f JG |
114 | The @file{config/mh-*}, @file{xm-*.h} and @file{*-xdep.c} files are for |
115 | host support. Similarly, the @file{config/mt-*}, @file{tm-*.h} and | |
97f3cb72 RP |
116 | @file{*-tdep.c} files are for target support. The question is, what |
117 | features or aspects of a debugging or cross-debugging environment are | |
118 | considered to be ``host'' support? | |
cfddbd02 | 119 | |
97f3cb72 RP |
120 | Defines and include files needed to build on the host are host support. |
121 | Examples are tty support, system defined types, host byte order, host | |
122 | float format. | |
cfddbd02 | 123 | |
97f3cb72 RP |
124 | Unix child process support is considered an aspect of the host. Since |
125 | when you fork on the host you are still on the host, the various macros | |
126 | needed for finding the registers in the upage, running @code{ptrace}, and such | |
127 | are all in the host-dependent files. | |
7f27984e | 128 | |
97f3cb72 | 129 | @c FIXME so what kinds of things are target support? |
7f27984e | 130 | |
97f3cb72 RP |
131 | This is still somewhat of a grey area; I (John Gilmore) didn't do the |
132 | @file{xm-*} and @file{tm-*} split for gdb (it was done by Jim Kingdon) | |
133 | so I have had to figure out the grounds on which it was split, and make | |
134 | my own choices as I evolve it. I have moved many things out of the xdep | |
135 | files actually, partly as a result of BFD and partly by removing | |
136 | duplicated code. | |

bbb5013f | 141 | |
97f3cb72 RP |
142 | Most of the work in making GDB compile on a new machine is in specifying |
143 | the configuration of the machine. This is done in a dizzying variety of | |
144 | header files and configuration scripts, which we hope to make more | |
145 | sensible soon. Let's say your new host is called an @var{xxx} (e.g. | |
146 | @samp{sun4}), and its full three-part configuration name is | |
147 | @code{@var{xarch}-@var{xvend}-@var{xos}} (e.g. @samp{sparc-sun-sunos4}). In | |
148 | particular: | |
149 | ||
b7becc8f | 150 | In the top level directory, edit @file{config.sub} and add @var{xarch}, |
97f3cb72 RP |
151 | @var{xvend}, and @var{xos} to the lists of supported architectures, |
152 | vendors, and operating systems near the bottom of the file. Also, add | |
153 | @var{xxx} as an alias that maps to | |
154 | @code{@var{xarch}-@var{xvend}-@var{xos}}. You can test your changes by | |
155 | running | |
bbb5013f | 156 | |
97f3cb72 RP |
157 | @example |
158 | ./config.sub @var{xxx} | |
159 | @end example | |
160 | @noindent | |
161 | and | |
162 | @example | |
163 | ./config.sub @code{@var{xarch}-@var{xvend}-@var{xos}} | |
164 | @end example | |
165 | @noindent | |
166 | which should both respond with @code{@var{xarch}-@var{xvend}-@var{xos}} | |
167 | and no error messages. | |
bbb5013f | 168 | |
b7becc8f RP |
169 | Now, go to the @file{bfd} directory and |
170 | create a new file @file{bfd/hosts/h-@var{xxx}.h}. Examine the | |
97f3cb72 RP |
171 | other @file{h-*.h} files as templates, and create one that brings in the |
172 | right include files for your system, and defines any host-specific | |
173 | macros needed by GDB. | |
7f27984e | 174 | |
b7becc8f | 175 | Then edit @file{bfd/configure.in}. Add shell script code to recognize your |
97f3cb72 | 176 | @code{@var{xarch}-@var{xvend}-@var{xos}} configuration, and set |
b7becc8f RP |
177 | @code{my_host} to @var{xxx} when you recognize it. This will cause your |
178 | file @file{h-@var{xxx}.h} to be linked to @file{sysdep.h} at configuration | |
179 | time. | |
7f27984e | 180 | |
b7becc8f | 181 | Also, if this host requires any changes to the Makefile, create a file |
8cc1c08f | 182 | @file{bfd/config/mh-@var{xxx}}, which includes the required lines. |
7f27984e | 183 | |
b7becc8f RP |
184 | (If you have the binary utilities and/or GNU ld in the same tree, |
185 | you'll also have to edit @file{binutils/configure.in} or | |
186 | @file{ld/configure.in} to match what you've done in the @file{bfd} | |
187 | directory.) | |
97f3cb72 | 188 | |
8cc1c08f | 189 | It's possible that the @file{libiberty} and @file{readline} directories |
97f3cb72 RP |
190 | won't need any changes for your configuration, but if they do, you can |
191 | change the @file{configure.in} file there to recognize your system and | |
8cc1c08f | 192 | map to an @file{mh-@var{xxx}} file. Then add @file{mh-@var{xxx}} |
97f3cb72 RP |
193 | to the @file{config/} subdirectory, to set any makefile variables you |
194 | need. The only current options in there are things like @samp{-DSYSV}. | |
195 | ||
b7becc8f | 196 | Aha! Now to configure GDB itself! Edit |
97f3cb72 RP |
197 | @file{gdb/configure.in} to recognize your system and set @code{gdb_host} |
198 | to @var{xxx}, and (unless your desired target is already available) also | |
199 | set @code{gdb_target} to something appropriate (for instance, | |
200 | @var{xxx}). To handle new hosts, modify the segment after the comment | |
201 | @samp{# per-host}; to handle new targets, modify after @samp{# | |
202 | per-target}. | |
203 | @c Would it be simpler to just use different per-host and per-target | |
204 | @c *scripts*, and call them from {configure} ? | |
7f27984e | 205 | |
b7becc8f | 206 | Finally, you'll need to specify and define GDB's host- and |
8cc1c08f JG |
207 | target-dependent @file{.h} and @file{.c} files used for your |
208 | configuration; the next two chapters discuss those. | |

212 | @chapter Adding a New Host | |
7f27984e | 213 | |
97f3cb72 RP |
214 | Once you have specified a new configuration for your host |
215 | (@pxref{Config,,Adding a New Configuration}), there are two remaining | |
216 | pieces to making GDB work on a new machine. First, you have to make it | |
217 | host on the new machine (compile there, handle that machine's terminals | |
218 | properly, etc). If you will be cross-debugging to some other kind of | |
219 | system that's already supported, you are done. | |
46bc46eb | 220 | |
97f3cb72 RP |
221 | If you want to use GDB to debug programs that run on the new machine, |
222 | you have to get it to understand the machine's object files, symbol | |
b7becc8f | 223 | files, and interfaces to processes. @pxref{Target,,Adding a New Target} |
46bc46eb | 224 | |
aeb62c7b JG |
225 | Several files control GDB's configuration for host systems: |
226 | ||
227 | @table @file | |
8cc1c08f JG |
228 | @item gdb/config/mh-@var{xxx} |
229 | Specifies Makefile fragments needed when hosting on machine @var{xxx}. | |
230 | In particular, this lists the required machine-dependent object files, | |
231 | by defining @samp{XDEPFILES=@dots{}}. Also | |
232 | specifies the header file which describes host @var{xxx}, by defining | |
97f3cb72 RP |
233 | @samp{XM_FILE= xm-@var{xxx}.h}. You can also define @samp{CC}, |
234 | @samp{REGEX} and @samp{REGEX1}, @samp{SYSV_DEFINE}, @samp{XM_CFLAGS}, | |
aeb62c7b JG |
235 | @samp{XM_ADD_FILES}, @samp{XM_CLIBS}, @samp{XM_CDEPS}, |
236 | etc.; see @file{Makefile.in}. | |
237 | ||
238 | @item gdb/xm-@var{xxx}.h | |
239 | (@file{xm.h} is a link to this file, created by configure). | |
240 | Contains C macro definitions describing the host system environment, | |
241 | such as byte order, host C compiler and library, ptrace support, | |
242 | and core file structure. Crib from existing @file{xm-*.h} files | |
243 | to create a new one. | |
244 | ||
245 | @item gdb/@var{xxx}-xdep.c | |
246 | Contains any miscellaneous C code required for this machine | |
247 | as a host. On some machines it doesn't exist at all. | |
248 | @end table | |
46bc46eb | 249 | |
97f3cb72 RP |
250 | There are some ``generic'' versions of routines that can be used by |
251 | various host systems. These can be customized in various ways by macros | |
252 | defined in your @file{xm-@var{xxx}.h} file. If these routines work for | |
253 | the @var{xxx} host, you can just include the generic file's name (with | |
254 | @samp{.o}, not @samp{.c}) in @code{XDEPFILES}. | |
46bc46eb | 255 | |
97f3cb72 RP |
256 | Otherwise, if your machine needs custom support routines, you will need |
257 | to write routines that perform the same functions as the generic file. | |
258 | Put them into @code{@var{xxx}-xdep.c}, and put @code{@var{xxx}-xdep.o} | |
259 | into @code{XDEPFILES}. | |
46bc46eb | 260 | |
97f3cb72 | 261 | @subheading Generic Host Support Files |
46bc46eb | 262 | |

46bc46eb | 264 | |
97f3cb72 | 265 | @item infptrace.c |
aeb62c7b JG |
266 | This is the low level interface to inferior processes for systems |
267 | using the Unix @code{ptrace} call in a vanilla way. | |
46bc46eb | 268 | |
aeb62c7b | 269 | @item coredep.c::fetch_core_registers() |
46bc46eb | 270 | Support for reading registers out of a core file. This routine calls |
aeb62c7b JG |
271 | @code{register_addr()}, see below. |
272 | Now that BFD is used to read core files, virtually all machines should | |
273 | use @code{coredep.c}, and should just provide @code{fetch_core_registers} in | |
493cf018 | 274 | @code{@var{xxx}-xdep.c} (or @code{REGISTER_U_ADDR} in @code{xm-@var{xxx}.h}). |
ca714d03 | 275 | |
aeb62c7b | 276 | @item coredep.c::register_addr() |
97f3cb72 | 277 | If your @code{xm-@var{xxx}.h} file defines the macro |
493cf018 JG |
278 | @code{REGISTER_U_ADDR(addr, blockend, regno)}, it should be defined to |
279 | set @code{addr} to the offset within the @samp{user} | |
280 | struct of GDB register number @code{regno}. @code{blockend} is the | |
281 | offset within the ``upage'' of @code{u.u_ar0}. | |
282 | If @code{REGISTER_U_ADDR} is defined, | |
d98259f8 RP |
283 | @file{coredep.c} will define the @code{register_addr()} function and use |
284 | the macro in it. If you do not define @code{REGISTER_U_ADDR}, but you | |
97f3cb72 RP |
285 | are using the standard @code{fetch_core_registers()}, you will need to |
286 | define your own version of @code{register_addr()}, put it into your | |
287 | @code{@var{xxx}-xdep.c} file, and be sure @code{@var{xxx}-xdep.o} is in | |
288 | the @code{XDEPFILES} list. If you have your own | |
289 | @code{fetch_core_registers()}, you may not need a separate | |
290 | @code{register_addr()}. Many custom @code{fetch_core_registers()} | |
291 | implementations simply locate the registers themselves.@refill | |
ca714d03 | 292 | @end table |
46bc46eb | 293 | |
97f3cb72 | 294 | Object files needed when the target system is an @var{xxx} are listed |
8cc1c08f | 295 | in the file @file{config/mt-@var{xxx}}, in the makefile macro |
97f3cb72 RP |
296 | @samp{TDEPFILES = }@dots{}. The header file that defines the target |
297 | system should be called @file{tm-@var{xxx}.h}, and should be specified | |
8cc1c08f | 298 | as the value of @samp{TM_FILE} in @file{config/mt-@var{xxx}}. You can |
97f3cb72 RP |
299 | also define @samp{TM_CFLAGS}, @samp{TM_CLIBS}, and @samp{TM_CDEPS} in |
300 | there; see @file{Makefile.in}. | |
1dbe1ef7 | 301 | |
b7becc8f RP |
302 | Now, you are now ready to try configuring GDB to compile for your system. |
303 | From the top level (above @file{bfd}, @file{gdb}, etc), do: | |
1dbe1ef7 | 304 | |
7f09f15f | 305 | @example |
97f3cb72 | 306 | ./configure @var{xxx} +target=vxworks960 |
7f09f15f | 307 | @end example |
1dbe1ef7 JG |
308 | |
309 | This will configure your system to cross-compile for VxWorks on | |
310 | the Intel 960, which is probably not what you really want, but it's | |
311 | a test case that works at this stage. (You haven't set up to be | |
97f3cb72 | 312 | able to debug programs that run @emph{on} @var{xxx} yet.) |
1dbe1ef7 JG |
313 | |
314 | If this succeeds, you can try building it all with: | |
315 | ||
7f09f15f JG |
316 | @example |
317 | make | |
318 | @end example | |
1dbe1ef7 JG |
319 | |
320 | Good luck! Comments and suggestions about this section are particularly | |
97f3cb72 RP |
321 | welcome; send them to @samp{bug-gdb@@prep.ai.mit.edu}. |
322 | ||
323 | When hosting GDB on a new operating system, to make it possible to debug | |
324 | core files, you will need to either write specific code for parsing your | |
325 | OS's core files, or customize @file{bfd/trad-core.c}. First, use | |
326 | whatever @code{#include} files your machine uses to define the struct of | |
327 | registers that is accessible (possibly in the u-area) in a core file | |
328 | (rather than @file{machine/reg.h}), and an include file that defines whatever | |
329 | header exists on a core file (e.g. the u-area or a @samp{struct core}). Then | |
330 | modify @code{trad_unix_core_file_p()} to use these values to set up the | |
331 | section information for the data segment, stack segment, any other | |
332 | segments in the core file (perhaps shared library contents or control | |
333 | information), ``registers'' segment, and if there are two discontiguous | |
334 | sets of registers (e.g. integer and float), the ``reg2'' segment. This | |
335 | section information basically delimits areas in the core file in a | |
336 | standard way, which the section-reading routines in BFD know how to seek | |
337 | around in. | |
338 | ||
b7becc8f RP |
339 | Then back in GDB, you need a matching routine called |
340 | @code{fetch_core_registers()}. If you can use the generic one, it's in | |
341 | @file{core-dep.c}; if not, it's in your @file{@var{xxx}-xdep.c} file. | |
342 | It will be passed a char pointer to the entire ``registers'' segment, | |
343 | its length, and a zero; or a char pointer to the entire ``regs2'' | |
344 | segment, its length, and a 2. The routine should suck out the supplied | |
345 | register values and install them into GDB's ``registers'' array. | |

1dbe1ef7 | 358 | |
aeb62c7b | 359 | @table @file |
8cc1c08f JG |
360 | @item gdb/config/mt-@var{ttt} |
361 | Contains a Makefile fragment specific to this target. | |
aeb62c7b | 362 | Specifies what object files are needed for target @var{ttt}, by |
8cc1c08f | 363 | defining @samp{TDEPFILES=@dots{}}. |
aeb62c7b | 364 | Also specifies the header file which describes @var{ttt}, by defining |
8cc1c08f | 365 | @samp{TM_FILE= tm-@var{ttt}.h}. You can also define @samp{TM_CFLAGS}, |
aeb62c7b JG |
366 | and other Makefile variables here; see @file{Makefile.in}. |
367 | ||
368 | @item gdb/tm-@var{ttt}.h | |
369 | (@file{tm.h} is a link to this file, created by configure). | |
370 | Contains macro definitions about the target machine's | |
371 | registers, stack frame format and instructions. | |
372 | Crib from existing @file{tm-*.h} files when building a new one. | |
373 | ||
374 | @item gdb/@var{ttt}-tdep.c | |
375 | Contains any miscellaneous code required for this target machine. | |
376 | On some machines it doesn't exist at all. Sometimes the macros | |
377 | in @file{tm-@var{ttt}.h} become very complicated, so they are | |
378 | implemented as functions here instead, and the macro is simply | |
379 | defined to call the function. | |
380 | ||
381 | @item gdb/exec.c | |
382 | Defines functions for accessing files that are | |
97f3cb72 RP |
383 | executable on the target system. These functions open and examine an |
384 | exec file, extract data from one, write data to one, print information | |
385 | about one, etc. Now that executable files are handled with BFD, every | |
386 | target should be able to use the generic exec.c rather than its | |
387 | own custom code. | |
388 | ||
aeb62c7b JG |
389 | @item gdb/@var{arch}-pinsn.c |
390 | Prints (disassembles) the target machine's instructions. | |
391 | This file is usually shared with other target machines which use the | |
392 | same processor, which is why it is @file{@var{arch}-pinsn.c} rather | |
393 | than @file{@var{ttt}-pinsn.c}. | |
394 | ||
395 | @item gdb/@var{arch}-opcode.h | |
396 | Contains some large initialized | |
397 | data structures describing the target machine's instructions. | |
398 | This is a bit strange for a @file{.h} file, but it's OK since | |
399 | it is only included in one place. @file{@var{arch}-opcode.h} is shared | |
400 | between the debugger and the assembler, if the GNU assembler has been | |
401 | ported to the target machine. | |
402 | ||
403 | @item gdb/tm-@var{arch}.h | |
404 | This often exists to describe the basic layout of the target machine's | |
405 | processor chip (registers, stack, etc). | |
406 | If used, it is included by @file{tm-@var{xxx}.h}. It can | |
407 | be shared among many targets that use the same processor. | |
408 | ||
409 | @item gdb/@var{arch}-tdep.c | |
410 | Similarly, there are often common subroutines that are shared by all | |
411 | target machines that use this particular architecture. | |
412 | @end table | |
413 | ||
414 | When adding support for a new target machine, there are various areas | |
415 | of support that might need change, or might be OK. | |
416 | ||
1dbe1ef7 JG |
417 | If you are using an existing object file format (a.out or COFF), |
418 | there is probably little to be done. See @file{bfd/doc/bfd.texinfo} | |
419 | for more information on writing new a.out or COFF versions. | |
420 | ||
421 | If you need to add a new object file format, you are beyond the scope | |
422 | of this document right now. Look at the structure of the a.out | |
97f3cb72 | 423 | and COFF support, build a transfer vector (@code{xvec}) for your new format, |
aeb62c7b | 424 | and start populating it with routines. Add it to the list in |
1dbe1ef7 JG |
425 | @file{bfd/targets.c}. |
426 | ||
97f3cb72 RP |
427 | If you are adding a new operating system for an existing CPU chip, add a |
428 | @file{tm-@var{xos}.h} file that describes the operating system | |
429 | facilities that are unusual (extra symbol table info; the breakpoint | |
430 | instruction needed; etc). Then write a | |
431 | @file{tm-@var{xarch}-@var{xos}.h} that just @code{#include}s | |
432 | @file{tm-@var{xarch}.h} and @file{tm-@var{xos}.h}. (Now that we have | |
1dbe1ef7 | 433 | three-part configuration names, this will probably get revised to |
97f3cb72 RP |
434 | separate the @var{xos} configuration from the @var{xarch} |
435 | configuration.) | |

475 | @code{initialize_@var{lang}} routine and have it call | |
476 | @samp{add_language(@var{lang}_language_defn)} to tell the rest of GDB | |
477 | that your language exists. You'll need some other supporting variables | |
478 | and functions, which will be used via pointers from your | |
479 | @code{@var{lang}_language_defn}. See the declaration of @code{struct | |
480 | language_defn} in @file{language.h}, and the other @file{*-exp.y} files, | |

483 | @item Add any evaluation routines, if necessary |
484 | ||
485 | If you need new opcodes (that represent the operations of the language), | |
486 | add them to the enumerated type in @file{expression.h}. Add support | |
487 | code for these operations in @code{eval.c:evaluate_subexp()}. Add cases | |
488 | for new opcodes in two functions from @file{parse.c}: | |
489 | @code{prefixify_subexp()} and @code{length_of_subexp()}. These compute | |
490 | the number of @code{exp_element}s that a given operation takes up. | |
491 | ||
492 | @item Update some existing code | |
493 | ||
494 | Add an enumerated identifier for your language to the enumerated type | |
495 | @code{enum language} in @file{defs.h}. | |
496 | ||
497 | Update the routines in @file{language.c} so your language is included. These | |
498 | routines include type predicates and such, which (in some cases) are | |
499 | language dependent. If your language does not appear in the switch | |
500 | statement, an error is reported. | |
501 | ||
502 | Also included in @file{language.c} is the code that updates the variable | |
503 | @code{current_language}, and the routines that translate the | |
504 | @code{language_@var{lang}} enumerated identifier into a printable | |
505 | string. | |
506 | ||
507 | Update the function @code{_initialize_language} to include your language. This | |
508 | function picks the default language upon startup, so is dependent upon | |
509 | which languages that GDB is built for. | |
510 | ||
b7becc8f RP |
511 | Update @code{allocate_symtab} in @file{symfile.c} and/or symbol-reading |
512 | code so that the language of each symtab (source file) is set properly. | |
513 | This is used to determine the language to use at each stack frame level. | |
514 | Currently, the language is set based upon the extension of the source | |
515 | file. If the language can be better inferred from the symbol | |
516 | information, please set the language of the symtab in the symbol-reading | |
517 | code. | |
97f3cb72 RP |
518 | |
519 | Add helper code to @code{expprint.c:print_subexp()} to handle any new | |

524 | ||
525 | Add a call to @code{@var{lang}_parse()} and @code{@var{lang}_error} in | |
526 | @code{parse.c:parse_exp_1()}. | |
527 | ||
528 | @item Use macros to trim code | |
529 | ||
530 | The user has the option of building GDB for some or all of the | |
531 | languages. If the user decides to build GDB for the language | |
532 | @var{lang}, then every file dependent on @file{language.h} will have the | |
533 | macro @code{_LANG_@var{lang}} defined in it. Use @code{#ifdef}s to | |
534 | leave out large routines that the user won't need if he or she is not | |
535 | using your language. | |
536 | ||
537 | Note that you do not need to do this in your YACC parser, since if GDB | |
538 | is not build for @var{lang}, then @file{@var{lang}-exp.tab.o} (the | |
539 | compiled form of your parser) is not linked into GDB at all. | |

594 | @chapter Partial Symbol Tables | |
595 | ||
596 | GDB has three types of symbol tables. | |
597 | ||
598 | @itemize @bullet | |
599 | @item full symbol tables (symtabs). These contain the main | |
600 | information about symbols and addresses. | |
601 | @item partial symbol tables (psymtabs). These contain enough | |
602 | information to know when to read the corresponding | |
603 | part of the full symbol table. | |
604 | @item minimal symbol tables (msymtabs). These contain information | |
605 | gleaned from non-debugging symbols. | |
606 | @end itemize | |
607 | ||
608 | This section describes partial symbol tables. | |
609 | ||
610 | A psymtab is constructed by doing a very quick pass over an executable | |
611 | file's debugging information. Small amounts of information are | |
612 | extracted -- enough to identify which parts of the symbol table will | |
613 | need to be re-read and fully digested later, when the user needs the | |
614 | information. The speed of this pass causes GDB to start up very | |
615 | quickly. Later, as the detailed rereading occurs, it occurs in small | |
616 | pieces, at various times, and the delay therefrom is mostly invisible to | |
617 | the user. (@xref{Symbol Reading}.) | |
618 | ||
619 | The symbols that show up in a file's psymtab should be, roughly, those | |
620 | visible to the debugger's user when the program is not running code from | |
621 | that file. These include external symbols and types, static | |
622 | symbols and types, and enum values declared at file scope. | |
623 | ||
624 | The psymtab also contains the range of instruction addresses that the | |
625 | full symbol table would represent. | |
626 | ||
627 | The idea is that there are only two ways for the user (or much of | |
628 | the code in the debugger) to reference a symbol: | |
629 | ||
630 | @itemize @bullet | |
631 | ||
632 | @item by its address | |
633 | (e.g. execution stops at some address which is inside a function | |
634 | in this file). The address will be noticed to be in the | |
635 | range of this psymtab, and the full symtab will be read in. | |
636 | @code{find_pc_function}, @code{find_pc_line}, and other @code{find_pc_@dots{}} | |
637 | functions handle this. | |
638 | ||
639 | @item by its name | |
640 | (e.g. the user asks to print a variable, or set a breakpoint on a | |
641 | function). Global names and file-scope names will be found in the | |
642 | psymtab, which will cause the symtab to be pulled in. Local names will | |
643 | have to be qualified by a global name, or a file-scope name, in which | |
644 | case we will have already read in the symtab as we evaluated the | |
645 | qualifier. Or, a local symbol can be referenced when | |
646 | we are "in" a local scope, in which case the first case applies. | |
647 | @code{lookup_symbol} does most of the work here. | |
648 | ||
649 | @end itemize | |
650 | ||
651 | The only reason that psymtabs exist is to cause a symtab to be read in | |
652 | at the right moment. Any symbol that can be elided from a psymtab, | |
653 | while still causing that to happen, should not appear in it. Since | |
654 | psymtabs don't have the idea of scope, you can't put local symbols in | |
655 | them anyway. Psymtabs don't have the idea of the type of a symbol, | |
656 | either, so types need not appear, unless they will be referenced by | |
657 | name. | |
658 | ||
659 | It is a bug for GDB to behave one way when only a psymtab has been read, | |
660 | and another way if the corresponding symtab has been read in. Such | |
661 | bugs are typically caused by a psymtab that does not contain all the | |
662 | visible symbols, or which has the wrong instruction address ranges. | |
663 | ||
664 | The psymtab for a particular section of a symbol-file (objfile) | |
665 | could be thrown away after the symtab has been read in. The symtab | |
666 | should always be searched before the psymtab, so the psymtab will | |
667 | never be used (in a bug-free environment). Currently, | |
668 | psymtabs are allocated on an obstack, and all the psymbols themselves | |
669 | are allocated in a pair of large arrays on an obstack, so there is | |
670 | little to be gained by trying to free them unless you want to do a lot | |
671 | more work. | |

97f3cb72 | 674 | @chapter Binary File Descriptor Library Support for GDB |
7f09f15f JG |
675 | |
676 | BFD provides support for GDB in several ways: | |
677 | ||
678 | @table @emph | |
679 | @item identifying executable and core files | |
680 | BFD will identify a variety of file types, including a.out, coff, and | |
681 | several variants thereof, as well as several kinds of core files. | |
682 | ||
683 | @item access to sections of files | |
684 | BFD parses the file headers to determine the names, virtual addresses, | |
685 | sizes, and file locations of all the various named sections in files | |
686 | (such as the text section or the data section). GDB simply calls | |
687 | BFD to read or write section X at byte offset Y for length Z. | |
688 | ||
689 | @item specialized core file support | |
690 | BFD provides routines to determine the failing command name stored | |
691 | in a core file, the signal with which the program failed, and whether | |
692 | a core file matches (i.e. could be a core dump of) a particular executable | |
693 | file. | |
694 | ||
695 | @item locating the symbol information | |
696 | GDB uses an internal interface of BFD to determine where to find the | |
697 | symbol information in an executable file or symbol-file. GDB itself | |
698 | handles the reading of symbols, since BFD does not ``understand'' debug | |
699 | symbols, but GDB uses BFD's cached information to find the symbols, | |
700 | string table, etc. | |
701 | @end table | |
702 | ||

eb752e4e JG |
708 | @chapter Symbol Reading |
709 | ||
710 | GDB reads symbols from "symbol files". The usual symbol file is the | |
711 | file containing the program which gdb is debugging. GDB can be directed | |
712 | to use a different file for symbols (with the ``symbol-file'' | |
713 | command), and it can also read more symbols via the ``add-file'' and ``load'' | |
714 | commands, or while reading symbols from shared libraries. | |
715 | ||
716 | Symbol files are initially opened by @file{symfile.c} using the BFD | |
717 | library. BFD identifies the type of the file by examining its header. | |
718 | @code{symfile_init} then uses this identification to locate a | |
719 | set of symbol-reading functions. | |
720 | ||
721 | Symbol reading modules identify themselves to GDB by calling | |
722 | @code{add_symtab_fns} during their module initialization. The argument | |
723 | to @code{add_symtab_fns} is a @code{struct sym_fns} which contains | |
724 | the name (or name prefix) of the symbol format, the length of the prefix, | |
725 | and pointers to four functions. These functions are called at various | |
726 | times to process symbol-files whose identification matches the specified | |
727 | prefix. | |
728 | ||
729 | The functions supplied by each module are: | |
730 | ||
731 | @table @code | |
97f3cb72 | 732 | @item @var{xxx}_symfile_init(struct sym_fns *sf) |
eb752e4e JG |
733 | |
734 | Called from @code{symbol_file_add} when we are about to read a new | |
735 | symbol file. This function should clean up any internal state | |
736 | (possibly resulting from half-read previous files, for example) | |
737 | and prepare to read a new symbol file. Note that the symbol file | |
738 | which we are reading might be a new "main" symbol file, or might | |
739 | be a secondary symbol file whose symbols are being added to the | |
740 | existing symbol table. | |
741 | ||
97f3cb72 | 742 | The argument to @code{@var{xxx}_symfile_init} is a newly allocated |
eb752e4e JG |
743 | @code{struct sym_fns} whose @code{bfd} field contains the BFD |
744 | for the new symbol file being read. Its @code{private} field | |
745 | has been zeroed, and can be modified as desired. Typically, | |
746 | a struct of private information will be @code{malloc}'d, and | |
747 | a pointer to it will be placed in the @code{private} field. | |
748 | ||
97f3cb72 | 749 | There is no result from @code{@var{xxx}_symfile_init}, but it can call |
eb752e4e JG |
750 | @code{error} if it detects an unavoidable problem. |
751 | ||
97f3cb72 | 752 | @item @var{xxx}_new_init() |
eb752e4e JG |
753 | |
754 | Called from @code{symbol_file_add} when discarding existing symbols. | |
755 | This function need only handle | |

767 | ||
d98259f8 | 768 | @code{sf} points to the struct sym_fns originally passed to |
97f3cb72 | 769 | @code{@var{xxx}_sym_init} for possible initialization. @code{addr} is the |
d98259f8 RP |
770 | offset between the file's specified start address and its true address |
771 | in memory. @code{mainline} is 1 if this is the main symbol table being | |

795 | @chapter Cleanups | |
7f09f15f | 796 | |
97f3cb72 RP |
797 | Cleanups are a structured way to deal with things that need to be done |
798 | later. When your code does something (like @code{malloc} some memory, or open | |
799 | a file) that needs to be undone later (e.g. free the memory or close | |
800 | the file), it can make a cleanup. The cleanup will be done at some | |
801 | future point: when the command is finished, when an error occurs, or | |
802 | when your code decides it's time to do cleanups. | |
7f09f15f | 803 | |
97f3cb72 RP |
804 | You can also discard cleanups, that is, throw them away without doing |
805 | what they say. This is only done if you ask that it be done. | |
7f09f15f | 806 | |
97f3cb72 | 807 | Syntax: |
7f09f15f | 808 | |
97f3cb72 RP |
809 | @table @code |
810 | @item @var{old_chain} = make_cleanup (@var{function}, @var{arg}); | |
811 | Make a cleanup which will cause @var{function} to be called with @var{arg} | |
812 | (a @code{char *}) later. The result, @var{old_chain}, is a handle that can be | |
813 | passed to @code{do_cleanups} or @code{discard_cleanups} later. Unless you are | |
814 | going to call @code{do_cleanups} or @code{discard_cleanups} yourself, | |
815 | you can ignore the result from @code{make_cleanup}. | |
7f09f15f | 816 | |
7f09f15f | 817 | |
97f3cb72 RP |
818 | @item do_cleanups (@var{old_chain}); |
819 | Perform all cleanups done since @code{make_cleanup} returned @var{old_chain}. | |
820 | E.g.: | |
821 | @example | |
822 | make_cleanup (a, 0); | |
823 | old = make_cleanup (b, 0); | |
824 | do_cleanups (old); | |
825 | @end example | |
826 | @noindent | |
827 | will call @code{b()} but will not call @code{a()}. The cleanup that calls @code{a()} will remain | |
828 | in the cleanup chain, and will be done later unless otherwise discarded.@refill | |
7f09f15f | 829 | |
97f3cb72 RP |
830 | @item discard_cleanups (@var{old_chain}); |
831 | Same as @code{do_cleanups} except that it just removes the cleanups from the | |
832 | chain and does not call the specified functions. | |
7f09f15f | 833 | |
97f3cb72 | 834 | @end table |
7f09f15f | 835 | |
97f3cb72 RP |
836 | Some functions, e.g. @code{fputs_filtered()} or @code{error()}, specify that they |
837 | ``should not be called when cleanups are not in place''. This means | |
838 | that any actions you need to reverse in the case of an error or | |
839 | interruption must be on the cleanup chain before you call these functions, | |
840 | since they might never return to your code (they @samp{longjmp} instead). | |

97f3cb72 | 844 | @chapter Wrapping Output Lines |
7f09f15f | 845 | |
97f3cb72 RP |
846 | Output that goes through @code{printf_filtered} or @code{fputs_filtered} or |
847 | @code{fputs_demangled} needs only to have calls to @code{wrap_here} added | |
848 | in places that would be good breaking points. The utility routines | |
849 | will take care of actually wrapping if the line width is exceeded. | |
7f09f15f | 850 | |
97f3cb72 RP |
851 | The argument to @code{wrap_here} is an indentation string which is printed |
852 | @emph{only} if the line breaks there. This argument is saved away and used | |
853 | later. It must remain valid until the next call to @code{wrap_here} or | |
854 | until a newline has been printed through the @code{*_filtered} functions. | |
855 | Don't pass in a local variable and then return! | |
7f09f15f | 856 | |
97f3cb72 RP |
857 | It is usually best to call @code{wrap_here()} after printing a comma or space. |
858 | If you call it before printing a space, make sure that your indentation | |
859 | properly accounts for the leading space that will print if the line wraps | |
860 | there. | |
7f09f15f | 861 | |
97f3cb72 RP |
862 | Any function or set of functions that produce filtered output must finish |
863 | by printing a newline, to flush the wrap buffer, before switching to | |
864 | unfiltered (``@code{printf}'') output. Symbol reading routines that print | |
865 | warnings are a good example. | |

871 | A frame is a construct that GDB uses to keep track of calling and called | |

873 | ||
8cc1c08f JG |
874 | @table @code |
875 | @item FRAME_FP | |
876 | in the machine description has no meaning to the machine-independent | |
edbf28ce JG |
877 | part of GDB, except that it is used when setting up a new frame from |
878 | scratch, as follows: | |
879 | ||
880 | @example | |
881 | create_new_frame (read_register (FP_REGNUM), read_pc ())); | |
882 | @end example | |
883 | ||
8cc1c08f JG |
884 | Other than that, all the meaning imparted to @code{FP_REGNUM} is imparted by |
885 | the machine-dependent code. So, @code{FP_REGNUM} can have any value that | |
886 | is convenient for the code that creates new frames. (@code{create_new_frame} | |
887 | calls @code{INIT_EXTRA_FRAME_INFO} if it is defined; that is where you should | |
888 | use the @code{FP_REGNUM} value, if your frames are nonstandard.) | |
889 | ||
890 | @item FRAME_CHAIN | |
891 | Given a GDB frame, determine the address of the calling function's | |
892 | frame. This will be used to create a new GDB frame struct, and then | |
893 | @code{INIT_EXTRA_FRAME_INFO} and @code{INIT_FRAME_PC} will be called for | |
894 | the new frame. | |

1481 | The default value means that u.u_ar0 @emph{points to} the location of the | |
