[commit] Cleanup: Remove dead FILL_FPXREGSET code

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

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.
