Description Mark Lam 2017-04-20 16:03:46 PDT
Experience shows that we never use the 2nd arg. So, let's remove it to reduce the footprint at each probe site. Also fix the MacroAssembler::print() function so that it is a no-op when !ENABLE(MASM_PROBE). This will allow us to have print() statements in JIT code without a lot of #if ENABLE(MASM_PROBE)s later.

I've done builds for ARMv7, ARM64, x86, and x86_64 with this patch, and ran a smoke test of printing something using the MASM print. I also did a build with !ENABLE(MASM_PROBE) to confirm that MASM print becomes a no-op in that case.
