Hi all,
I have turned on post- register allocation scheduling for x86 (Anton
is investigating a problem on Linux, but it's *so far* working well on
Darin). It's a very expensive codegen pass that can easily increase
the codegen time by 10% or more. For this reason, I've added a new
code generation optimization level CodeGenOpt::Less. If you are using
the LLVM x86 JIT, you *should* initialize the with this optimization
level to avoid running the pass (see
LLVMTargetMachine::addPassesToEmitMachineCode).
