From f245ae5a4a78d5a02b3b9e2dae819077a56d81e7 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Thu, 25 Jul 2013 00:34:29 +0000 Subject: Replace the "NoFramePointerElimNonLeaf" target option with a function attribute. There's no need to specify a flag to omit frame pointer elimination on non-leaf nodes...(Honestly, I can't parse that option out.) Use the function attribute stuff instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187093 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/fp-elim.ll | 74 ++++++++++++++++++++++++++++----------------- 1 file changed, 46 insertions(+), 28 deletions(-) (limited to 'test/CodeGen/X86/fp-elim.ll') diff --git a/test/CodeGen/X86/fp-elim.ll b/test/CodeGen/X86/fp-elim.ll index d43ee36143..583388cc71 100644 --- a/test/CodeGen/X86/fp-elim.ll +++ b/test/CodeGen/X86/fp-elim.ll @@ -1,42 +1,60 @@ ; RUN: llc < %s -march=x86 -asm-verbose=false | FileCheck %s -check-prefix=FP-ELIM ; RUN: llc < %s -march=x86 -asm-verbose=false -disable-fp-elim | FileCheck %s -check-prefix=NO-ELIM -; RUN: llc < %s -march=x86 -asm-verbose=false -disable-non-leaf-fp-elim | FileCheck %s -check-prefix=NON-LEAF ; Implement -momit-leaf-frame-pointer ; rdar://7886181 -define i32 @t1() nounwind readnone { +define i32 @t1() "no-frame-pointer-elim-non-leaf"="false" nounwind readnone { entry: -; FP-ELIM-LABEL: t1: -; FP-ELIM-NEXT: movl -; FP-ELIM-NEXT: ret - -; NO-ELIM-LABEL: t1: -; NO-ELIM-NEXT: pushl %ebp -; NO-ELIM: popl %ebp -; NO-ELIM-NEXT: ret - -; NON-LEAF-LABEL: t1: -; NON-LEAF-NEXT: movl -; NON-LEAF-NEXT: ret +; FP-ELIM-LABEL: t1: +; FP-ELIM-NEXT: movl +; FP-ELIM-NEXT: ret + +; NO-ELIM-LABEL: t1: +; NO-ELIM-NEXT: pushl %ebp +; NO-ELIM: popl %ebp +; NO-ELIM-NEXT: ret ret i32 10 } -define void @t2() nounwind { +define void @t2() "no-frame-pointer-elim-non-leaf"="false" nounwind { entry: -; FP-ELIM-LABEL: t2: -; FP-ELIM-NOT: pushl %ebp -; FP-ELIM: ret - -; NO-ELIM-LABEL: t2: -; NO-ELIM-NEXT: pushl %ebp -; NO-ELIM: popl %ebp -; NO-ELIM-NEXT: ret - -; NON-LEAF-LABEL: t2: -; NON-LEAF-NEXT: pushl %ebp -; NON-LEAF: popl %ebp -; NON-LEAF-NEXT: ret +; FP-ELIM-LABEL: t2: +; FP-ELIM-NOT: pushl %ebp +; FP-ELIM: ret + +; NO-ELIM-LABEL: t2: +; NO-ELIM-NEXT: pushl %ebp +; NO-ELIM: popl %ebp +; NO-ELIM-NEXT: ret + tail call void @foo(i32 0) nounwind + ret void +} + +define i32 @t3() "no-frame-pointer-elim-non-leaf"="true" nounwind readnone { +entry: +; FP-ELIM-LABEL: t3: +; FP-ELIM-NEXT: movl +; FP-ELIM-NEXT: ret + +; NO-ELIM-LABEL: t3: +; NO-ELIM-NEXT: pushl %ebp +; NO-ELIM: popl %ebp +; NO-ELIM-NEXT: ret + ret i32 10 +} + +define void @t4() "no-frame-pointer-elim-non-leaf"="true" nounwind { +entry: +; FP-ELIM-LABEL: t4: +; FP-ELIM-NEXT: pushl %ebp +; FP-ELIM: popl %ebp +; FP-ELIM-NEXT: ret + +; NO-ELIM-LABEL: t4: +; NO-ELIM-NEXT: pushl %ebp +; NO-ELIM: popl %ebp +; NO-ELIM-NEXT: ret tail call void @foo(i32 0) nounwind ret void } -- cgit v1.2.3
