rjmccall posted:my guess, without reading any gcc code (which i'm not allowed to do, lol), is that linus has actually diagnosed the problem correctly, but it's buried under a long discussion of what's probably a red herring (also under a giant pile of assholeishness). the red zone is almost certainly a distraction here. gcc appears to be spilling a simple constant (which is definitely screwy) to a slot which should be well within the stack frame, except unfortunately it's doing that spill just before the stack frame has actually been established. there isn't normally a reason you'd need to materialize a constant in the prologue; wild guess, there's something weird (inline assembly?) at the start of the function, and some piece of code is trying to position a "hey, i need this constant now" assertion before that and isn't being careful enough to avoid the prologue. that mistake is also confusing the register allocator, hence the spill u could write pretty much anything about this & that'd work for me
