/* Create a prototype *BSD/i386 target. The client can override it
with local methods. */
extern struct target_ops *i386bsd_target (void);
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.
