--- Comment #5 from Wilco <wilco at gcc dot gnu.org> --- Author: wilco Date: Mon Jul 8 17:02:35 2019 New Revision: 273238 URL: https://gcc.gnu.org/viewcvs?rev=273238&root=gcc&view=rev Log: Turn of ipa-ra in builtins test (PR91059) The gcc.c-torture/execute/builtins/lib directory contains a reimplementation of many C library string functions, which causes non-trivial register allocation bugs with LTO and static linked libraries. To fix this long-standing test issue, turn off ipa-ra which avoids the register corruption across calls. All builtin torture tests now pass on aarch64-none-elf. Committed as obvious. testsuite/ PR testsuite/91059 PR testsuite/78529 * gcc.c-torture/execute/builtins/builtins.exp: Add -fno-ipa-ra.
