Subject: [AArch64] Add vector int to float conversions.
X-Git-Tag: upstream/12.2.0~69966
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1709ff9b5c53b13140819feae5e381fac22f6416;p=platform%2Fupstream%2Fgcc.git

[AArch64] Add vector int to float conversions.

gcc/
	* config/aarch64/aarch64-builtins.c
	(aarch64_fold_builtin): Fold float conversions.
	* config/aarch64/aarch64-simd-builtins.def
	(floatv2si, floatv4si, floatv2di): New.
	(floatunsv2si, floatunsv4si, floatunsv2di): Likewise.
	* config/aarch64/aarch64-simd.md
	(<optab><fcvt_target><VDQF:mode>2): New, expands to float and floatuns.
	* config/aarch64/iterators.md (FLOATUORS): New.
	(optab): Add float, floatuns.
	(su_optab): Likewise.
