[X86] Adding a new instruction JUMPB
Hi llvm-dev,
In the review of the LLVM-side changes to support XRay (which is now
upstream as http://reviews.llvm.org/rL275367) we hit one particular case
where we had to hack around the fact that we have no way to force the
emission of a short relative jump. It's even come up that jump relaxation
can come in and (at least with clang -O0) relax jumps to use the longer
version of the jump
