[4.9] Add several improvements for AArch64
Backported from GCC 5. 2015-04-30 Kyrylo Tkachov <kyrylo.tkachov@arm.com> Properly handle mvn-register and add EON+shift pattern and cost appropriately * config/aarch64/aarch64.md (*eor_one_cmpl_<SHIFT:optab><mode>3_alt): New pattern. (*eor_one_cmpl_<SHIFT:optab>sidi3_alt_ze): Likewise. * config/aarch64/aarch64.c (aarch64_rtx_costs): Handle MVN-shift appropriately. Handle alternative EON form. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222637 138bc75d-0d04-0410-961f-82ee72b054a4 2015-04-30 Kyrylo Tkachov <kyrylo.tkachov@arm.com> Properly cost FABD pattern * config/aarch64/aarch64.c (aarch64_rtx_costs): Handle pattern for fabd in ABS case. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222638 138bc75d-0d04-0410-961f-82ee72b054a4 2015-05-01 Kyrylo Tkachov <kyrylo.tkachov@arm.com> Remember to cost operand 0 in FP compare-with-0.0 case * config/aarch64/aarch64.c (aarch64_rtx_costs, COMPARE case): Add cost of op0 in the compare-with-fpzero case. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222673 138bc75d-0d04-0410-961f-82ee72b054a4 2015-05-01 Wilco Dijkstra <wdijkstr@arm.com> Fix aarch64_rtx_costs of PLUS/MINUS * gcc/config/aarch64/aarch64.c (aarch64_rtx_costs): Calculate cost of op0 and op1 in PLUS and MINUS cases. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@222676 138bc75d-0d04-0410-961f-82ee72b054a4 2015-07-27 Wilco Dijkstra <wdijkstr@arm.com> Improve spill code - swap order in shl pattern * config/aarch64/aarch64.md (aarch64_ashl_sisd_or_int_<mode>3): Place integer variant first. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@226247 138bc75d-0d04-0410-961f-82ee72b054a4 2015-07-27 Wilco Dijkstra <wdijkstr@arm.com> Improve spill code - swap order in shr patterns * gcc/config/aarch64/aarch64.md (aarch64_lshr_sisd_or_int_<mode>3): Place integer variant first. (aarch64_ashr_sisd_or_int_<mode>3): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@226253 138bc75d-0d04-0410-961f-82ee72b054a4 2015-08-04 Pawel Kupidura <pawel.kupidura@arm.com> * config/aarch64/aarch64.c: Change inner loop statement cost to be consistent with other targets.
