Hi everyone,
During my optimisation travels, I frequently stumble across lone NOP
instructions in the compiled assembly language. Normally I leave these
alone, but occasionally I stumble across things like this:
...
movq $0,24(%rbx)
.Lj1859:
nop
.Lj1858:
movq %rbp,%rcx
...
And there are jumps elsewhere that go to one label or the other. Is
there any reason why a jump should lead to the NOP, or can they all be
redirected to after the NOP instruction?
