gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Variable Objects): Document what happens
to the children of a varobj and its update range when -var-update
returns that the varobj's type changed.
This patch introduces a new language-specific callback for varobj
objects, allowing us to move the language-specific bits of the
varobj_value_is_changeable_p routine to language-specific functions.
This is more elegant than testing for the varobj's language...
gdb/ChangeLog:
* varobj.c (default_value_is_changeable_p): New function,
extracted from varobj_value_is_changeable_p. Add declaration.
(ada_value_is_changeable_p): New function, extracted from
varobj_value_is_changeable_p. Add declaration.
(struct language_specific): New field "value_is_changeable_p".
(languages): Add entries for new field.
(varobj_create): Set language before calling install_new_value.
(varobj_value_is_changeable_p): Reimplement to call the varobj's
"value_is_changeable_p" language callback.
This patch adds varobj support for Ada variables. Most of the code
is implemented in a separate Ada-specific file called ada-varobj.c.
The only bits in varobj.c are the functions used as the hooks in
the language-specific varobj's vector.
gdb/ChangeLog:
* ada-varobj.h, ada-varobj.c: New files.
* Makefile.in (SFILES): Add ada-varobj.c.
(HFILES_NO_SRCDIR): Add ada-varobj.h.
(COMMON_OBS): Add ada-varobj.o.
This patch introduces the framework necessary to support type mutations.
The only language that currently provides a language-specific hook for
that feature is Ada, but the hook remain unimplemented for now. The
actual implementation is tied to the rest of the varobj code for Ada,
and thus will be provided then.
gdb/ChangeLog:
* varobj.c (ada_value_has_mutated): Add declaration. New function.
(struct language_specific): New field "value_has_mutated".
(languages): Set field "value_has_mutated" in each entry of array.
(varobj_value_has_mutated): New function.
(varobj_udpdate): Add handling of type mutation.
(value_of_root): Add handling of type mutation.
(ada_value_has_mutated): New function.
On ia64-linux, GDB sometimes prints the following error when trying
to switch to a different task:
(gdb) task 3
Register 0 is not available
This is a random failure that sometimes happens, sometimes does not.
The error comes from the fact that the libunwind library is requesting
the value of register 0 (zero): This eventually leads us to
ia64-linux-nat.c:ia64_linux_fetch_register.
This function relies on ia64_cannot_fetch_register to determine
whether or not we have access to the register's value. The ptrace
interface does not provide the r0 value, and so we end up telling
the regcache that this register's value is not available. And yet,
for r0, we do not need to ask ptrace for its value, since it is
always zero.
So, the fix was to add a special rule for supplying a nul value
when regnum == IA64_GR0_REGNUM.
gdb/ChangeLog:
* ia64-linux-nat.c (ia64_linux_fetch_register): Add special
handling for r0.
set_gdbarch_process_record.
Initialize `arm_swi_record' field.
* arm-tdep.c (arm_process_record): New function.

(decode_insn): New function.
(thumb_record_branch): New function.
(thumb_record_ldm_stm_swi(): New function.
(thumb_record_misc): New function.
(thumb_record_ld_st_stack): New function.
(thumb_record_ld_st_imm_offset): New function.
(thumb_record_ld_st_reg_offset(): New function.
(thumb_record_add_sub_cmp_mov): New function.
(thumb_record_shift_add_sub): New function.

* arm-tdep.h (struct gdbarch_tdep): New field 'arm_swi_record'
The common code has a sim_core_trans_addr() helper that only the m32r code
uses. Move the inline extern in the m32r code to the proper common header.

Similar to logic in the cris exp, attempt a simple compile and if it fails
(presumably due to the compiler being broken), skip all the related tests.
Fortunately, most tests (~600 out of ~800) are pure assembly, so people should
still get pretty good coverage.

* ldemul.c (before_allocation_default): Revert last change.
ldlang.c (lang_add_section): Likewise.
(strip_excluded_output_sections): Don't strip output sections with
user input sections when emitrelocations, unless all are SEC_EXCLUDE.
ld/testsuite/
* ld-powerpc/vxworks-relax.rd: Remove check on reloc section
file offset and reloc symbol indices.
Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.
