Subject: [ARM][7/7] Convert FP mnemonics to UAL | f{ld,st}m -> v{ld,st}m
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b27832edcf1a344c9e2ba94c68b0ceef2d141f7b;p=gcc.git

[ARM][7/7] Convert FP mnemonics to UAL | f{ld,st}m -> v{ld,st}m

	* config/arm/arm.md (vfp_pop_multiple_with_writeback): Use vldm
	mnemonic instead of fldmfdd.
	* config/arm/arm.c (vfp_output_fstmd): Rename to...
	(vfp_output_vstmd): ... This.  Convert output to UAL syntax.
	Output vpush when address register is SP.
	* config/arm/arm-protos.h (vfp_output_fstmd): Rename to...
	(vfp_output_vstmd): ... This.
	* config/arm/vfp.md (push_multi_vfp): Update call to
	vfp_output_vstmd.
