From: Richard Sandiford Date: Thu, 15 Aug 2019 08:08:49 +0000 (+0000) Subject: [AArch64] Use SVE [SU]ABD in conditional arithmetic X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9730c5ccd522cd955bcb6e65295023621cade8b6;p=gcc.git [AArch64] Use SVE [SU]ABD in conditional arithmetic This patch extends the [SU]ABD support so that it handles conditional arithmetic. We're relying on combine for this, since there's no associated IFN_COND_* (yet?). 2019-08-15 Richard Sandiford Kugan Vivekanandarajah gcc/ * config/aarch64/aarch64-sve.md (*aarch64_cond_abd_2) (*aarch64_cond_abd_any): New patterns. gcc/testsuite/ * gcc.target/aarch64/sve/cond_abd_1.c: New test. * gcc.target/aarch64/sve/cond_abd_1_run.c: Likewise. * gcc.target/aarch64/sve/cond_abd_2.c: Likewise. * gcc.target/aarch64/sve/cond_abd_2_run.c: Likewise. * gcc.target/aarch64/sve/cond_abd_3.c: Likewise. * gcc.target/aarch64/sve/cond_abd_3_run.c: Likewise. * gcc.target/aarch64/sve/cond_abd_4.c: Likewise. * gcc.target/aarch64/sve/cond_abd_4_run.c: Likewise. * gcc.target/aarch64/sve/cond_abd_5.c: Likewise. * gcc.target/aarch64/sve/cond_abd_5_run.c: Likewise.
