Consolidate x86 debug register code for BSD native targets. Move the debug register support code from amd64bsd-nat.c and i386bsd-nat.c into a shared x86bsd-nat.c. Instead of setting up x86_dr_low in amd64fbsd-nat.c and i386fbsd-nat.c, add a x86bsd_target function that creates a new target that inherits from inf_ptrace and sets up x86 debug registers if supported. In addition to initializing x86_dr_low, the x86bsd target installs a custom mourn_inferior target operation to clean up the x86 debug register state. Previously this was only done on amd64. Now it will be done for both i386 and amd64. The i386bsd_target and amd64bsd_target functions create targets that inherit from x86bsd rather than inf_ptrace. gdb/ChangeLog: * Makefile.in [HFILES_NO_SRCDIR]: Replace 'amd64bsd-nat.h' with 'x86bsd-nat.h'. * amd64bsd-nat.c: Include 'x86bsd-nat.h' instead of 'amd64bsd-nat.h'.

Normalize names of some source files Most tdep/nat files are named: <cpu>-<os>-tdep.c <cpu>-<os>-nat.c A few files do not respect this scheme. This patch renames them so that they are consistent with the rest of the files. It builds fine with --enable-targets=all, but that doesn't test the nat files. I can only hope that my grep skill is good enough. gdb/ChangeLog: * Makefile.in (ALL_64_TARGET_OBS, ALL_TARGET_OBS, HFILES_NO_SRCDIR, ALLDEPFILES): Rename files. * alphabsd-nat.c: Rename to ... *

/* Low level x86 XSAVE info. */
extern size_t x86bsd_xsave_len;
Add support for the x86 XSAVE extended state on FreeBSD/x86. Recognize NT_X86_XSTATE notes in FreeBSD process cores. Recent FreeBSD versions include a note containing the XSAVE state for each thread in the process when XSAVE is in use. The note stores a copy of the current XSAVE mask in a reserved section of the machine-defined XSAVE state at the same offset as Linux's NT_X86_XSTATE note. For native processes, use the PT_GETXSTATE_INFO ptrace request to determine if XSAVE is enabled, and if so the active XSAVE state mask (that is, the value of %xcr0 for the target process) as well as the size of XSAVE state area. Use the PT_GETXSTATE and PT_SETXSTATE requests to fetch and store the XSAVE state, respectively, in the BSD x86 native targets. In addition, the FreeBSD amd64 and i386 native targets now include "read_description" target methods to determine the correct x86 target description for the current XSAVE mask. On FreeBSD amd64 this also properly returns an i386 target description for 32-bit binaries which allows the 64-bit GDB to run 32-bit binaries. Note that the ptrace changes are in the BSD native targets, not the FreeBSD-specific native targets since that is where the other ptrace register accesses occur. Of the other BSDs, NetBSD and DragonFly use XSAVE in the kernel but do not currently export the extended state via ptrace(2). OpenBSD does not currently support XSAVE. bfd/ChangeLog: * elf.c (elfcore_grok_note): Recognize NT_X86_XSTATE on FreeBSD.

/* Create a prototype *BSD/x86 target. The client can override it
with local methods. */
Consolidate x86 debug register code for BSD native targets. Move the debug register support code from amd64bsd-nat.c and i386bsd-nat.c into a shared x86bsd-nat.c. Instead of setting up x86_dr_low in amd64fbsd-nat.c and i386fbsd-nat.c, add a x86bsd_target function that creates a new target that inherits from inf_ptrace and sets up x86 debug registers if supported. In addition to initializing x86_dr_low, the x86bsd target installs a custom mourn_inferior target operation to clean up the x86 debug register state. Previously this was only done on amd64. Now it will be done for both i386 and amd64. The i386bsd_target and amd64bsd_target functions create targets that inherit from x86bsd rather than inf_ptrace. gdb/ChangeLog: * Makefile.in [HFILES_NO_SRCDIR]: Replace 'amd64bsd-nat.h' with 'x86bsd-nat.h'. * amd64bsd-nat.c: Include 'x86bsd-nat.h' instead of 'amd64bsd-nat.h'.

Normalize names of some source files Most tdep/nat files are named: <cpu>-<os>-tdep.c <cpu>-<os>-nat.c A few files do not respect this scheme. This patch renames them so that they are consistent with the rest of the files. It builds fine with --enable-targets=all, but that doesn't test the nat files. I can only hope that my grep skill is good enough. gdb/ChangeLog: * Makefile.in (ALL_64_TARGET_OBS, ALL_TARGET_OBS, HFILES_NO_SRCDIR, ALLDEPFILES): Rename files. * alphabsd-nat.c: Rename to ... *
