From 6c0b8df123c24ef3c14305698eb2910bcf5979ce Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 9 Apr 2019 07:50:51 +0000 Subject: [PATCH] SVE fallout from PR90006 2019-04-08 Richard Sandiford gcc/ * tree-vect-data-refs.c (vect_get_smallest_scalar_type): Always use gimple_expr_type for load and store calls. Skip over the condition argument in a conditional internal function. Protect use of TREE_INT_CST_LOW.
