From 134982daa9bcd87f79c357e3a2686804b9baddd9 Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Wed, 20 Oct 2010 22:03:58 +0000 Subject: More accurate estimate / tracking of register pressure. - Initial register pressure in the loop should be all the live defs into the loop. Not just those from loop preheader which is often empty. - When an instruction is hoisted, update register pressure from loop preheader to the original BB. - Treat only use of a virtual register as kill since the code is still SSA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116956 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/2009-02-26-MachineLICMBug.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test/CodeGen/X86/2009-02-26-MachineLICMBug.ll') diff --git a/test/CodeGen/X86/2009-02-26-MachineLICMBug.ll b/test/CodeGen/X86/2009-02-26-MachineLICMBug.ll index 4a97ac35af..0b5b7bdd94 100644 --- a/test/CodeGen/X86/2009-02-26-MachineLICMBug.ll +++ b/test/CodeGen/X86/2009-02-26-MachineLICMBug.ll @@ -1,4 +1,4 @@ -; RUN: llc < %s -march=x86-64 -mattr=+sse3,+sse41 -stats |& grep {7 machine-licm} +; RUN: llc < %s -march=x86-64 -mattr=+sse3,+sse41 -stats |& grep {8 machine-licm} ; RUN: llc < %s -march=x86-64 -mattr=+sse3,+sse41 | FileCheck %s ; rdar://6627786 ; rdar://7792037 -- cgit v1.2.3
