Hello,
while looking at gregset handling for other reasons, I noticed that we
still have a block guarded by #ifdef FILL_FPXREGSET in gregset.h.
This is now dead code as the i386 target was changed to use the new
gdbarch_core_regset_sections mechanism instead; linux-nat.c no longer
uses any of the definitions depending on FILL_FPXREGSET.
This patch cleans this up by removing the block in gregset.h and the
definition of FILL_FPXREGSET in config/i386/nm-linux.h; the latter
now makes the complete file superfluous.
Tested on i386-linux, committed to mainline.
Bye,
Ulrich
ChangeLog:
* gregset.h (GDB_FPXREGSET_T): Remove.
(gdb_fpxregset_t): Likewise.
(supply_fpxregset): Remove prototype.
(fill_fpxregset): Likewise.
* i386-linux-nat.c (supply_fpxregset): Remove.
(fill_fpxregset): Likewise.
(fetch_fpxregs): Inline supply_fpxregset call.
(store_fpxregs): Inline fill_fpxregset call.
* config/i386/linux.mh: Set NAT_FILE to config/nm-linux.h.
* config/i386/nm-linux.h: Remove file.

Now that this file is gone, it no longer needs to be listed in
HFILES_NO_SRCDIR in the Makefile. Sorry for overlooking this.
Tested on i386-linux, committed to mainline.
