From 4bdb8c3dca3b518a6ca8dbaf60068f7e897ccc0e Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 2 Oct 2019 13:11:45 +0000 Subject: [PATCH] Fix MIPS call-clobbered-*.c tests Jeff pointed out that gcc.target/mips/call-clobbered-4.c started failing after the function-abi series. This is because IRA used to treat partly call-clobbered registers as hard conflicts and so wouldn't consider them for -fcaller-saves. Now that we treat call clobbers the same way regardless of where they come from, we can use $f21 as a caller-save register. This in turn means that -Os is no longer a special case in call-clobbered-3.c. (The new code is the same size as the old code.) 2019-10-02 Richard Sandiford gcc/testsuite/ * gcc.target/mips/call-clobbered-3.c: Remove skip for -Os. * gcc.target/mips/call-clobbered-4.c: Delete.
