[LLVMdev] X86TarIgetLowering::LowerToBT
> icc generates testq for 0-30 and btq for 31-63. > That seems like a small bug in the bit 31 case. You can’t use testq for bit 31, because the immediate gets sign-extended. You *can* use the 32b form, of course.

[LLVMdev] X86TarIgetLowering::LowerToBT
I’ll be happy to run it for you. Do you want Intel64, x86 or both? The Intel compiler doesn’t have a –Oz option. It has –Os and –O[123]. Also, FWIW, one of the Intel compiler experts on BT will comment on this thread, and on our rules for BT usage later this afternoon. Kevin B.
