Subject: i386: Extend MOVNTDQ support to cover various packed integer types
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=41d7bf31278cc166d9a3b4073da09afbaef78fc4;p=thirdparty%2Fgcc.git

i386: Extend MOVNTDQ support to cover various packed integer types

As the associated mode iterator VI8 shows, MOVNTDQ is only used for
*QI and *DI packed integer modes, this patch extends it to cover *HI
and *SI packed integer modes.

gcc/ChangeLog:

	* config/i386/sse.md (define_mode_attr sse2): Add V4SI/V8SI/V16SI/
	V8HI/V16HI/V32HI.
	(<sse2>_movnt<mode>): Change mode iterator from VI8 to VI_AVX_AVX512F.
	(define_mode_iterator STORENT_MODE): Add V4SI/V8SI/V16SI/V8HI/V16HI/
	V32HI/V16QI/V32QI/V64QI.
