From efc8f0d8d16144627d0fad4c43496f8e6e869161 Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 27 Oct 2015 11:54:51 +0000 Subject: [PATCH] Remove constant handling from fold_builtin_{,f}abs fold_builtin_fabs and fold_builtin_abs had code to handle constant arguments, but this simply duplicated what the following fold_build1_loc would do for ABS_EXPR. Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi. gcc/ * builtins.c (fold_builtin_fabs): Remove constant handling. (fold_builtin_abs): Likewise.
