Wow, three bug reports for the same problem in one day! We should
probably make fixing this a real priority :-).
The following code cleanups will hopefully be applied to GDB 5.1.

Solaris 8 x86 CURSES_H problem
http://sources.redhat.com/ml/gdb/2000-07/msg00038.html
Compiler warnings.
-Eliminate all warnings for at least one host/target for the flags:
--Wimplicit -Wreturn-type -Wcomment -Wtrigraphs -Wformat -Wparentheses
--Wpointer-arith -Wuninitialized
+Eliminate warnings for all targets on at least one host for one of the
+-W flags. Flags up for debate include: -Wswitch -Wcomment -trigraphs
+-Wtrigraphs -Wunused-function -Wunused-label -Wunused-variable
+-Wunused-value -Wchar-subscripts -Wtraditional -Wshadow -Wcast-qual
+-Wcast-align -Wwrite-strings -Wconversion -Wstrict-prototypes

+
+Deprecate, if not delete, the following:
+
+ register[]
+ register_valid[]
+ register_buffer()
+ REGISTER_BYTE()
+ Replaced by, on the target side
+ supply_register()
+ and on core-gdb side:
+ {read,write}_register_gen()
+ Remote.c will need to use something
+ other than REGISTER_BYTE() and
+ REGISTER_RAW_SIZE() when unpacking
+ [gG] packets.
+
+ STORE_PSEUDO_REGISTER
+ FETCH_PSEUDO_REGISTER
+ Now handed by the methods
+ gdbarch_{read,write}_register()
+ which sits between core GDB and
+ the register cache.
+
+ REGISTER_CONVERTIBLE
+ REGISTER_CONVERT_TO_RAW
+ REGISTER_CONVERT_TO_VIRTUAL
+ I think these three are redundant.
+ gdbarch_register_{read,write} can
+ do any conversion it likes.
+
+ REGISTER_VIRTUAL_SIZE
+ MAX_REGISTER_VIRTUAL_SIZE
+ REGISTER_VIRTUAL_TYPE
+ I think these can be replaced by
+ the pair:
+ FRAME_REGISTER_TYPE(frame, regnum)
+ REGISTER_TYPE(regnum)
+
+ DO_REGISTERS_INFO
+ Replace with
+ FRAME_REGISTER_INFO (frame, ...)
+
+ REGISTER_SIM_REGNO()
+ If nothing else rename this so that
+ how it relates to rawreg and the
+ regnum is clear.
+
+ REGISTER_BYTES
+ The size of the cache can be computed
+ on the fly.
+
+ IS_TRAPPED_INTERNALVAR
+ The pseudo registers should eventually make
+ this redundant.

-Revised UDP support (was: Re: [Fwd: [patch] UDP transport support])
-http://sourceware.cygnus.com/ml/gdb-patches/2000-04/msg00000.html
-
-(Broken) support for GDB's remote protocol across UDP is to be
-included in the follow-on release.
+Investigate changing --target=a29k-amd-udi to a29k-*-coff* and
+rationalize *.mt files. The got-ya is in remote-eb.c - it has its own
+custom tty manipulation - it should be using the serial object.
-It should be noted that UDP can only work when the [Gg] packet fits in
-a single UDP packet.
+--
-There is also much debate over the merit of this.
+Rename read_register{,_pid}() to read_unsigned_register{,_pid}().
--
Replace the file gdb/CONTRIBUTE with a file that is generated from the
gdb/doc/*.texinfo directory.
+--
+
+Rewrite/break up sparcl-tdep.c so that it uses ser*.c as the mechanism
+for accessing either the serial or UDP port.

New Features and Fixes
--
-Get the TUI working on all platforms.
+Fix TUI
+
+ o readline/*.h bitrot
+
+ The TUI isn't up-to-date with
+ respect to the readline currently
+ bundled with GDB. Importing a
+ new readline is on the 5.1 wish
+ list so this can only get worse.
+
+ Grep for things like term_cursor_move.
+
+ (To be honest, I don't see anyone
+ importing a new readline before 5.1 is
+ out)
+
+ o tui.c:va_catch_errors() bitrot
+
+ This nasty piece of work used knowledge
+ of the internals of GDBs error functions :-(
+ Ever since those internals were cleaned
+ up this code has been broken. :-(
+
+ o tuiWin.c:c_makeVisibleWithNewHeight() broken
+ tuiLayout.c:_extractDisplayStartAddr() broken
+
+ Both these function call find_line_pc()
+ incorrectly (wrong args, wrong return value).
+
+ I suspect this bug has always been there!
+ It had been hidden because those files
+ didn't include the necessary header files
+ from gdb proper :-(
+
+ o tuiRegs() host dependant
+
+ Not suprisingly, this isn't a very portable
+ section of code. However, I'm sure people
+ could live with no regs in the short to
+ medium term.
+
+ o defs.h: #include "tui.h" et.al.
+
+ I'm not sure where this came from.
+ It was a really bad idea.
+
+ To get things to compile I did a nasty
+ hack (Just declare what was needed and
+ replace any expressions like xx->y.z()
+ in GDB proper with function calls). I
+ could commit it slightly cleaned up if
+ you like.
+
+ Medium Term. the #ifdef TUI and TuiDo()
+ should be changed to hooks (like GDBTK).
+ The gdb-events.[hc] is there for that
+ purpose (1)
+
+ o tui.c:_tuiReset() host dependant
+
+ tui.c contains a lump of termio[s]
+ I suspect an equivalent block of
+ code can be lifted from readline.
+ An equivalent readline function may
+ even be available.
+
+ o curses.h vs ncurses.h.
+
+ Simple portability problem.
+
+ o subsetCompare()
+
+ This function is a mystery - where is it?
+
+ o tui-file.[hc] cleanup
+
+ This can be significantly simplified.
+
+ o The code should be pacified. (-Werror -W...)
+
+ There are plenty of #includes,
+ duplicate #includes, missing function decls
+ and the like.
+
+ Some of the problems I found were through
+ fixing a few of the warnings.
+
+ o The code should be GNUtified.
+
+ It would be very nice to have this code
+ look like the rest of GDB. That way people
+ would be more accepting of it as a true
+ gdb component.
+
+ Until it is GNUtified it is going to stick
+ out like a sore thumb to the programmer.
+
+ o The code should be clearly copyrighted
+
+ (FSF, with due credit to HP)

Remote protocol doco feedback.
Too much feedback to mention needs to be merged in (901660). Search
--
+Fix the ``!'' packet.
+
+JT reported that the existing targets do, in fact return ``OK'' so it
+is possible to merge remote and extended-remote targets.
+
+--
+
+Drop ``<address>'' from the [SsCc] packets.
+
+I don't think that GDB generates them so having it in the protocol is
+silly.
+
+--
+
+Fix doco on the ``q'' packet.
+
+It has evolved into a generic RPC. The notes should reflect this and,
+perhaps, the ``Q'' packet can be deprecated.
+
+The doco should mention that ``OK'' is a valid packet response.
+
+The doco should explain why ``OK'' needs to be a valid packet
+response.

Add the cycle step command.
http://sourceware.cygnus.com/ml/gdb/2000-q1/msg00237.html
Underlying problem is that the register file is target endian. If the
target endianess changes gdb doesn't know.
+Suggest encoding registers as NN!VALUE.
+
--
-Rename read_register{,_pid}() to read_unsigned_register{,_pid}().
+GDB should allow incomming packets to be larger than outgoing ones. A
+fully loaded T packet (containing all registers) can be very large -
+definitly larger than a corresponding Gg packet.
--
After that it needs to be multi-arched and made independent of any
host signal numbering.
+Once this is done, the signal enum can probably be moved to
+include/gdb so that it is available to embedded stubs.
+

Update ALPHA so that it uses ``struct frame_extra_info'' instead of
projects / deliverable / binutils-gdb.git / blobdiff
