From 203af58aea3ae341d38e5c2c5b390b0c31d25557 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Fri, 5 Dec 2008 21:47:27 +0000 Subject: Make LoopStrengthReduce smarter about hoisting things out of loops when they can be subsumed into addressing modes. Change X86 addressing mode check to realize that some PIC references need an extra register. (I believe this is correct for Linux, if not, I'm sure someone will tell me.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60608 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/loop-strength-reduce.ll | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'test/CodeGen/X86/loop-strength-reduce.ll') diff --git a/test/CodeGen/X86/loop-strength-reduce.ll b/test/CodeGen/X86/loop-strength-reduce.ll index 8bacbd9..8737101 100644 --- a/test/CodeGen/X86/loop-strength-reduce.ll +++ b/test/CodeGen/X86/loop-strength-reduce.ll @@ -1,7 +1,8 @@ -; RUN: llvm-as < %s | llc -march=x86 | \ -; RUN: grep {A(} | count 1 +; RUN: llvm-as < %s | llc -march=x86 -relocation-model=static | \ +; RUN: grep {A+} | count 2 ; -; Make sure the common loop invariant _A(reg) is hoisted up to preheader. +; Make sure the common loop invariant A is not hoisted up to preheader, +; since it can be subsumed into the addressing mode in all uses. @A = internal global [16 x [16 x i32]] zeroinitializer, align 32 ; <[16 x [16 x i32]]*> [#uses=2] -- cgit v1.1
