Passing arguments did not work when use_mi_command was set.

2014-05-13 Simon Marchi <simon.marchi@ericsson.com>
* lib/mi-support.exp (mi_run_cmd_full): Set arguments by calling
"-exec-arguments" or "set args" before running the inferior.
The message displayed by gdb is different when the inferior exits with
zero and non-zero values, this fix takes that into account.
gdb/testsuite/ChangeLog:
2014-05-13 Simon Marchi <simon.marchi@ericsson.com>
* lib/mi-support.exp (mi_expect_stop): Expect message for
inferiors that exit with non-zero exit code.
When linking statically, it's possible to hit this warning with IFUNC
or very large executables, due to .glink being unused.
* powerpc.cc (do_plt_fde_location): Handle zero length .glink.
Compare FDE contents with DW_CFA_nop rather than 0.
I happened to notice that print_macro_definition is indented
improperly. All the lines were a few extra spaces to the right.
This patch fixes the indentation.
Tested by rebuilding, committed.
2014-05-14 Tom Tromey <tromey@redhat.com>
* macrocmd.c (print_macro_definition): Reindent.
This patch fixes mi-file.exp fails on remote host. First, we can't
assume ${srcdir}/${subdir}/${srcfile} directory exists on remote host,
so this patch changes it to match ${srcfile} only on remote host.
Second, regexp pattern ".*/${srcfile}" isn't friendly to Windows path.
The file name is "basics.c" in my test env and can't match the pattern
due to "/" in it. Remove "/" from the pattern.

* gdb.mi/mi-file.exp (test_file_list_exec_source_file): Don't
match absolute path on remote host.
(test_file_list_exec_source_files): Remove "/" from the
pattern.
After I run test like this,
$ make check RUNTESTFLAGS='--host_board=local-remote-host dw2-basic.exp'
gdb.dwarf2/file1.txt in source tree was removed. In some gdb.dwarf2/*.exp,
file1.txt is copied to host and then removed at the end. However, in
local-remote-host-notty.exp, ${board}_download doesn't copy the file but
return the absolute path of the src file. 'remote_file host delete' at
the end will remove the file in source tree.
This patch is to overwrite ${board}_file, and specially make "delete"
option do nothing. This approach is used in gdbserver-base.exp and
remote-stdio-gdbserver.exp too.

should_resume is set to 1 at the beginning and never changed.

* infrun.c (resume): Remove should_resume (unused). Move up
declaration of resume_ptid.
to access a global as it expects a GOTPCREL relocation. This is really not
necessary as the linker could use a copy relocation to get around it. This
patch enables copy relocations with pie.
Context:
This is useful because currently the GCC compiler with option -fpie makes
every extern global access go through the GOT. That is because the compiler
cannot tell if a global will end up being defined in the executable or not
and is conservative. This ends up hurting performance when the binary is linked
as mostly static where most of the globals do end up being defined in the
executable. By allowing copy relocs with fPIE, the compiler need not generate
a GOTPCREL(GOT access) for any global access. It can safely assume that all
globals will be defined in the executable and generate a PC-relative access
instead. Gold can then create a copy reloc for only the undefined globals.
gold/
* symtab.h (may_need_copy_reloc): Remove check for position independent

This patch removes an unused macro from language.h. It also removes
the declaration of a function which is not defined.
I'm checking this in as obvious.
Tested by rebuilding.

* language.h (unop_type_check): Remove.
(binop_type_check): Don't declare.
With -pie and x86, the linker complains if it sees a PC-relative relocation
to access a global as it expects a GOTPCREL relocation. This is really not
necessary as the linker could use a copy relocation to get around it. This

* config/tc-mips.c (mips_set_options): Rename gp32 to gp throughout.

In mi_interpreter_init, multiple MI consoles/channels are created and a quoting
character is given. In mi_console_raw_packet, we check if the value is not 0
to decide if we should quote the string, but we don't use the value. It is
hardcoded to ". We might never use another quoting character than an actual
quote, but I suggest we change it, for correctness. There is not visible
behavior change.
I changed the latest fputs_unfiltered changed to fputc_unfiltered just to stay
consistent.

I think "set debugvarobj" has the wrong name.
It ought to be "set debug varobj", like gdb's other debug settings.
This patch makes the change.
I chose not to install deprecated aliases, since this is only a debug
setting; but if someone feels strongly about it I will add them.
Built and regtested on x86-64 Fedora 20.
2014-04-29 Tom Tromey <tromey@redhat.com>
* varobj.c (_initialize_varobj): Rename to "set debug varobj" and
"show debug varobj".

* msp430-sim.c (sim_open): Do not allocate memory over the
hardware multiply registers.
(get_op): Add support for reads from the hardware multiply
registers.
(put_op): Add support for writes to the hardware multiply
registers.
(msp430_step_once): Add support for the RETI instruction used by
the CPUX architecture.
This adds support for the load-link/store-conditional

The support is added in such way, that the cpu description not
only describes the mnemonics, but also the functionality.
A couple of fixes to typos in nearby/related code are also snuck
into this.
