From 700bfada6375546f82000bdd1b4cdbe87beebea5 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Thu, 27 May 2010 23:57:25 +0000 Subject: Add a -regalloc=default option that chooses a register allocator based on the -O optimization level. This only really affects llc for now because both the llvm-gcc and clang front ends override the default register allocator. I intend to remove that code later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104904 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/Passes.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'include/llvm/CodeGen') diff --git a/include/llvm/CodeGen/Passes.h b/include/llvm/CodeGen/Passes.h index 96fb8b907b..a8f4fbabe8 100644 --- a/include/llvm/CodeGen/Passes.h +++ b/include/llvm/CodeGen/Passes.h @@ -85,9 +85,10 @@ namespace llvm { /// FunctionPass *createDeadMachineInstructionElimPass(); - /// Creates a register allocator as the user specified on the command line. + /// Creates a register allocator as the user specified on the command line, or + /// picks one that matches OptLevel. /// - FunctionPass *createRegisterAllocator(); + FunctionPass *createRegisterAllocator(CodeGenOpt::Level OptLevel); /// LocalRegisterAllocation Pass - This pass register allocates the input code /// a basic block at a time, yielding code better than the simple register -- cgit v1.2.3-70-g09d2
