7 years ago[ARC] Allow CPU to be enforced via disassemble_info options
Anton Kolesov [Thu, 16 Mar 2017 12:21:31 +0000 (15:21 +0300)] 
[ARC] Allow CPU to be enforced via disassemble_info options

Currently print_insn_arc relies on BFD mach and ELF private headers to
distinguish between various ARC architectures.  Sometimes those values are not
correct or available, mainly in the case of debugging targets without and ELF
file available.  Changing a BFD mach is not a problem for the debugger, because
this is a generic BFD field, and GDB, for example, already sets it according to
information provided in XML target description or specified via GDB 'set arch'
command.  However, things are more complicated for ELF private headers, since
it requires existing of an actual ELF file.  To workaround this problem this
patch allows CPU model to be specified via disassemble info options.  If CPU is
specified in options, then it will take a higher precedence than whatever might
be specified in ELF file.

This is mostly needed for ARC EM and ARC HS, because they have the same
"architecture" (mach) ARCv2 and differ in their private ELF headers.  Other ARC
architectures can be distinguished between each other purely via "mach" field.

Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid
ARC CPU name as supported by GAS.  Note that this creates a seeming redundancy
with objdump -m/--architecture option, however -mEM and -mHS still result in
"ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual
effect on disassembler.

will help ensure that gas and disassembker use same option values for CPUs.

else.  This for example multiple C files to include arc-cpu.def, but define

7 years ago[ARC] Implement compatible function for ARC BFD architectures
Anton Kolesov [Fri, 17 Mar 2017 15:37:42 +0000 (18:37 +0300)] 
[ARC] Implement compatible function for ARC BFD architectures

The general rule for bfd_arch_info_type->compatible (A, B) is that if A and B
are compatible, then this function should return architecture that is more
"feature-rich", that is, can run both A and B.  ARCv2, EM and HS all has same
mach number, so bfd_default_compatible assumes they are the same, and returns
an A.  That causes issues with GDB, because GDB assumes that if machines are
compatible, then "compatible ()" always returns same machine regardless of
argument order.  As a result GDB gets confused because, for example,
compatible(ARCv2, EM) returns ARCv2, but compatible(EM, ARCv2) returns EM,
hence GDB is not sure if they are compatible and prints a warning.

Tom Tromey [Sun, 14 May 2017 17:12:14 +0000 (11:12 -0600)] 
Use watchpoint's language when re-parsing expression

PR rust/21484 notes that watch -location does not work with Rust:

    (gdb) watch -location a
    syntax error in expression, near `) 0x00007fffffffe0f4'.

update_watchpoint tries to tell gdb that the new expression it creates
has C syntax:

      /* The above expression is in C.  */
      b->language = language_c;

However, update_watchpoint doesn't actually use this language when
re-parsing the expression.

Originally I was going to fix this by saving and restoring the
language in update_watchpoint, but this regressed
gdb.dlang/watch-loc.exp, because the constructed expression actually
has D syntax (specifically the name is not parseable by C).

Next I looked at directly constructing an expression, and not relying
on the parser at all; but it seemed to me that upon a re-set, we'd
want to reparse the type, and there is no existing API to do this
correctly.

So, in the end I made a hook to let each language choose what
expression to use.  I made all the languages other than Rust use the C
expression, because that is the status quo ante.  However, this is
probably not truly correct.  After this patch, at least, it is easy to
correct by someone who knows the language(s) in question.

Regtested by the buildbot.

pr20882 testcase

-gdwarf-sections doesn't work on targets that lack support to emit
address size relative relocs.  The testcase as it was avoided
-gdwarf-sections doing anything by providing a non-empty .debug_line.
It's better to not use -gdwarf-sections.  Also, the testcase failed
to match the output for 16-bit address targets like avr.

Mark debug sections referenced by kept debug sections

If a debug section is referenced by a kept debug section, it should
also be kept.

Some targets, like mips, keep input files when there are some special
sections, like .gnu.attributes, even if input file is unused otherwise.
In this case, all debug sections are kept.  The new test will fail on
such targets.  We can either fix those targets or XFAIL the test.

7 years agoAdd alias command to cmd_list_element
Yao Qi [Wed, 17 May 2017 13:22:04 +0000 (14:22 +0100)] 
Add alias command to cmd_list_element

When we add alias command, we call add_alias_cmd and pass the alias name
and command name.  This implicitly requires the command and its prefix
commands are already added to cmdlist.  This may not be true, for example,

  add_com_alias ("tty", "set inferior-tty", class_alias, 0);

"inferior-tty" command is added to setlist, but setlist may not be added
to cmdlist (It depends on the order of related _initialize_XXX functions
called) so that we can't find "set inferior-tty" from cmdlist.

This patch fixes this problem by passing cmd_list_element of "inferior-tty"
to add_alias_cmd, so that cmd_list_element of "inferior-tty" doesn't have
to be reachable from cmdlist at that moment.
