Subject: [nvptx] Use define_insn parametrization
X-Git-Tag: upstream/12.2.0~23872
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8b72af17038e9b2451f4ded5d7a96e31825c412c;p=platform%2Fupstream%2Fgcc.git

[nvptx] Use define_insn parametrization

Parametrize some define_insn to simplify code in define_expands generating
those insns.

Build and reg-tested on x86_64 with nvptx accelerator.

2019-06-18  Tom de Vries  <tdevries@suse.de>

	* config/nvptx/nvptx-protos.h (gen_set_softstack_insn): Remove.
	* config/nvptx/nvptx.c (gen_set_softstack_insn): Remove.
	* config/nvptx/nvptx.md (define_insn "set_softstack_<mode>"): Rename to ...
	(define_insn "@set_softstack_<mode>"): ... this.
	(define_insn "omp_simt_enter_<mode>"): Rename to ...
	(define_insn "@omp_simt_enter_<mode>"): ... this.
	(define_insn "omp_simt_exit_<mode>"): Rename to ...
	(define_insn "@omp_simt_exit_<mode>"): ... this.
