...ng the automagic
interpretation. Implementing the automatic assembler variant for prefix
and immediate padding adds substantial complexity and I would very much
like not to bother with if I don't have to.
Current implementation details
We have support in the integrated assembler only for autopadding
suppression. This allows a LLVM based compiler to effectively apply
padding selectively. In particular, we've instrumented lowering from MI
to MC (X86MCInstLowering.cpp) to selectively disable padding around
constructs which are thought to be problematic. We do not have an
agreed upon s...
