Re: [PATCH][GCC][AArch64] Vectorise __builtin_signbit on aarch64

Hi all, Vectorise __builtin_signbit (v2sf, v4sf) with unsigned shift right vector instruction. Bootstrapped and tested on aarch64-none-linux-gnu. Assembly output for: $ aarch64-elf-gcc -S -O3 signbitv2sf.c -dp Before patch: foo: ldp w2, w1, [x1]// 37 [c=0 l=4]

Re: [PATCH][GCC][AArch64] Vectorise __builtin_signbit on aarch64

Hi Richard, New patch adds a new IFN_SIGNBIT internal function that maps to signbit_optab. gcc/ChangeLog: 2019-05-05 Przemyslaw Wirkus * gcc/internal-fn.def (SIGNBIT): New. * gcc/config/aarch64/aarch64-simd.md (signbitv4sf2): New expand defined.

[PATCH][GCC][AArch64] Vectorise __builtin_signbit on aarch64

Hi all, Vectorise __builtin_signbit (v4sf) with unsigned shift right vector instruction. Bootstrapped and tested on aarch64-none-linux-gnu. Assembly output for: $ aarch64-elf-gcc -S -O3 signbitv4sf.c -dp Before patch: foo: adrpx3, in // 37 [c=4 l=4] *movdi_aarch64/12
