From e2a05fdfd4798192493c582ec6528c975bfa9b0c Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Thu, 21 Nov 2019 12:03:54 +0000 Subject: [PATCH] [AArch64] Add -fno-vect-cost-model to sve2/whilerw_1.c Bumping the cost of vec_to_scalar made the .s loop in gcc.target/aarch64/sve2/whilerw_1.c use a runtime profitability check, like the .d version already did. Since the cost model isn't really being tested here, the most robust fix seemed to be to disable it, which I should really have done from the outset. 2019-11-21 Richard Sandiford gcc/testsuite/ * gcc.target/aarch64/sve2/whilerw_1.c: Add -fno-vect-cost-model. Require x0 in the .d test too.
