* sh-tdep.c (sh_gdbarch_init): Add show_regs settings for
bfd_mach_sh3_nommu, bfd_mach_sh2a_nofpu_or_sh3_nommu,
bfd_mach_sh2a_or_sh3e, bfd_mach_sh2a_or_sh4, bfd_mach_sh4_nommu_nofpu,
and bfd_mach_sh2a_nofpu_or_sh4_nommu_nofpu.
Move bfd_mach_sh2a_or_sh4 to use the same configuration as
bfd_mach_sh4.
* solib-darwin.c: Add an empty line after comment for functions.
(struct gdb_dyld_all_image_infos): Improve comment.
(DYLD_VERSION): Removed and replaced by ...
(DYLD_VERSION_MAX, DYLD_VERSION_MIN): ... New macros.
(darwin_dyld_version_ok): New function.
(darwin_load_image_infos): Call darwin_dyld_version_ok.
(darwin_current_sos): Ditto.
(darwin_solib_create_inferior_hook): Ditto.
* machoread.c: Add an empty line after comment for functions.
(oso_el_compare_name): New function.
(macho_add_oso_symfile): New function.
(macho_oso_symfile): Use macho_add_oso_symfile. Sort the oso
and optimize accesses to libraries.
(core_close): Clear it.
(add_to_thread_list): Fake a pid if one is not found on a Solaris
core. Add the inferior here. Always add the thread, don't use
thread_change_ptid.
(core_open): Don't add the main thread or the inferior here unless
we find that the core had no .reg/NN sections.
(get_core_register_section): Handle Solaris cores with fake pids.
(SYSCALL_SIGTRAP): New.
(status_to_str): Adjust.
(get_pending_status): Pending events in lp->waitstatus don't map
to any signal. Simplify.
(linux_handle_syscall_trap): New.
(linux_handle_extended_wait): When handling PTRACE_EVENT_CLONE
events, use linux_ops->to_resume instead of direct ptrace with
PTRACE_CONT. Remove all TRAP_IS_SYSCALL handling.
(wait_lwp): Handle syscall traps with linux_handle_syscall_trap,
and clear the sysgood bit.
(status_callback): Make it clearer and add comments.
(cancel_breakpoints_callback): Ignore if LP has waitstatus set.
(linux_nat_filter_event): Handle syscall traps with
linux_handle_syscall_trap, and clear the sysgood bit. Move the
check for storing siginfo to after handling extended statuses and
syscall traps. Store status in the lwp object.
(linux_wait_1): Don't swap the pending status out of the lwp
object until after deciding we found an lwp with an interesting
event. Requeue a new pending signal if we find one while getting
rid or a pending SIGSTOP we sent ourselves. Don't clear the
sysgood bit here.
* infrun.c (deal_with_syscall_event): Rename to ...
(handle_syscall_event): ... this. Always context switch and set
stop_pc, even if not catching the syscall. If not catching the
syscall, always resume with keep_going.
(handle_inferior_event): Adjust.
* gdbarch.c, gdbarch.h: Regenerate.
* arch-utils.c (default_displaced_step_hw_singlestep): New function.
* arch-utils.h (default_displaced_step_hw_singlestep): Add prototype.
* ppc-linux-tdep.c (ppc_displaced_step_hw_singlestep): New function.
(rs6000_gdbarch_init): Install it.
* infrun.c (displaced_step_fixup): Use new callback to determine
whether to "step" or "continue" displaced copy.
(resume): Likewise. Do not call maybe_software_singlestep
for displaced stepping.
(maybe_software_singlestep): Do not handle displaced stepping.
platforms that use function descriptors. Prefer to use function
pointer types instead of function types.
* linespec.c (decode_objc): Support function descriptors. Fully
initialize SAL result.
* objc-lang.c (find_methods): Support function descriptors.
Do not require function symbol to point to text section.
* ppc-sysv-tdep.c (ppc64_sysv_abi_push_dummy_call): When calling
via a function pointer, use the descriptor it points to.
* ia64-tdep.c (ia64_memory_insert_breakpoint): Extend the comment.
New variable shadow_slotnum, use it appropriately instead of slotnum.
Move shadow_len initialization before SLOTNUM adjustment, cover now the
whole remaining bundle. Error now on breakpoints requested for the
slot 2 of L-X bundles. Better sanity check the requested slot 1 of L-X
bundles.
(ia64_memory_remove_breakpoint): New variable shadow_slotnum, use it
appropriately instead of slotnum. Warn now on breakpoints requested
for the slot 2 of L-X bundles. Better sanity check the requested slot
1 of L-X bundles. Update the assertio check of PLACED_SIZE.
(ia64_breakpoint_from_pc): New variable shadow_slotnum, use it
appropriately instead of slotnum. Move *lenptr initialization before
SLOTNUM adjustment, cover now the whole remaining bundle. Error now
on breakpoints requested for the slot 2 of L-X bundles. Better sanity
check the requested slot 1 of L-X bundles. Simplify the returned
expression.
