[LLVMdev] Tell LLVM JIT to omit the frame pointer?

Take look at TargetOptions.h - http://llvm.org/doxygen/TargetOptions_8h_source.html

I thought FPO is enabled by default (I explicitly disable it), but try setting:

llvm::NoFramePointerElim = false;

Subject: [LLVMdev] Tell LLVM JIT to omit the frame pointer?

Hey guys,

Is there a way to force the LLVM JIT compiler to omit the frame pointer in its generated i386/amd64 code? I've got a complex situation in which the stack can potentially be moved around so I'd prefer that the base pointer doesn't get pushed there.
