fused indicates fused conditional jumps, jmp indicates unconditional jumps, call indicates direct
and indirect calls, ret indicates rets, indirect indicates indirect jumps.

with NOP. If the boundary's size is not 0, it should be a power of 2 and no less than 32. Branches
will be aligned to prevent from being across or against the boundary of specified size. The
default value 0 does not align branches.
--x86-branches-within-32B-boundaries - Align selected instructions to mitigate negative
performance impact of Intel's micro code update for errata skx102.
May break assumptions about labels corresponding to particular instructions, and should be used
with caution.
