--- Comment #5 from Tamar Christina <tnfchris at gcc dot gnu.org> --- Author: tnfchris Date: Wed Jun 27 08:08:48 2018 New Revision: 262178 URL: https://gcc.gnu.org/viewcvs?rev=262178&root=gcc&view=rev Log: Add SIMD to REG pattern for movhf without armv8.2-a support for AArch64 This fixes a regression where we don't have an instruction for pre Armv8.2-a to do a move of an fp16 value from a GP reg to a SIMD reg. This patch adds that pattern to movhf_aarch64 using a dup and only selectes it using a very low priority. This fixes an ICE at -O0. gcc/ 2018-06-20 Tamar Christina <tamar.christ...@arm.com> PR target/85769 * config/aarch64/aarch64.md (*movhf_aarch64): Add dup v0.4h pattern. gcc/testsuite/ 2018-06-20 Tamar Christina <tamar.christ...@arm.com> PR target/85769 * gcc.target/aarch64/f16_mov_immediate_3.c: New.
