r242384 - in /trunk/gcc: ChangeLog config/aarch...


Author: wilco
Date: Mon Nov 14 12:04:11 2016
New Revision: 242384

URL: https://gcc.gnu.org/viewcvs?rev=242384&root=gcc&view=rev
Log:
Currently the SBFM, UBFM and BFM instructions all use the attribute "bfm".
SBFM and UBFM include all shifts on AArch64, which are simpler than bitfield
insert.  Add a new bfx attribute for these instructions so that they can be
modelled more accurately in the future.  There is no difference in code 
generation.

	* config/aarch64/aarch64.md (aarch64_ashl_sisd_or_int_<mode>3)
	Use bfx attribute.
	(aarch64_lshr_sisd_or_int_<mode>3): Likewise.
	(aarch64_ashr_sisd_or_int_<mode>3): Likewise.
	(<optab>si3_insn_uxtw): Likewise.
	(<optab><mode>3_insn): Likewise.
	(<ANY_EXTEND:optab><GPI:mode>_ashl<SHORT:mode>): Likewise.
	(zero_extend<GPI:mode>_lshr<SHORT:mode>): Likewise.
	(extend<GPI:mode>_ashr<SHORT:mode>): Likewise.
	(<optab><mode>): Likewise.
	(insv<mode>): Likewise.
	(andim_ashift<mode>_bfiz): Likewise.
	* config/aarch64/thunderx.md (thunderx_shift): Add bfx.
	* config/arm/cortex-a53.md (cortex_a53_alu_shift): Likewise.
	* config/arm/cortex-a57.md (cortex_a57_alu): Add bfx.
	* config/arm/exynos-m1.md (exynos_m1_alu): Add bfx.
	(exynos_m1_alu_p): Likewise.
	* config/arm/types.md: Add bfx.
	* config/arm/xgene1.md (xgene1_bfm): Add bfx.
