From 54075bbea7e70fea6cdb9e5e89b066118c1d314b Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Thu, 21 Nov 2013 20:18:40 +0000 Subject: Merging r195339: ------------------------------------------------------------------------ r195339 | chapuni | 2013-11-21 02:55:15 -0800 (Thu, 21 Nov 2013) | 5 lines Revert r195317 (and r195333), "Teach ISel not to optimize 'optnone' functions." It broke, at least, i686 target. It is reproducible with "llc -mtriple=i686-unknown". FYI, it didn't appear to add either "-O0" or "-fast-isel". ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195375 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/Generic/isel-optnone.ll | 32 -------------------------------- 1 file changed, 32 deletions(-) delete mode 100644 test/CodeGen/Generic/isel-optnone.ll (limited to 'test/CodeGen/Generic') diff --git a/test/CodeGen/Generic/isel-optnone.ll b/test/CodeGen/Generic/isel-optnone.ll deleted file mode 100644 index f4916dafb8..0000000000 --- a/test/CodeGen/Generic/isel-optnone.ll +++ /dev/null @@ -1,32 +0,0 @@ -; RUN: llc -debug < %s -o /dev/null 2>&1 | FileCheck %s -; REQUIRES: asserts - -; Verify that the backend correctly overrides the optimization level -; of optnone functions during instruction selection. - -define float @foo(float %x) #0 { -entry: - %add = fadd fast float %x, %x - %add1 = fadd fast float %add, %x - ret float %add1 -} - -; CHECK-NOT: Changing optimization level for Function foo -; CHECK-NOT: Restoring optimization level for Function foo - -; Function Attrs: noinline optnone -define float @fooWithOptnone(float %x) #1 { -entry: - %add = fadd fast float %x, %x - %add1 = fadd fast float %add, %x - ret float %add1 -} - -; CHECK: Changing optimization level for Function fooWithOptnone -; CHECK-NEXT: Before: -O2 ; After: -O0 - -; CHECK: Restoring optimization level for Function fooWithOptnone -; CHECK-NEXT: Before: -O0 ; After: -O2 - -attributes #0 = { "unsafe-fp-math"="true" } -attributes #1 = { noinline optnone "unsafe-fp-math"="true" } -- cgit v1.2.3
