Remember glibc's awful, slower-than-generic-C pthread asm? It only happens to work if (C) callee doesn't clobber eax https://sourceware.org/ml/libc-alpha/2016-03/msg00160.html …

@bofh453 There's no way this code could possibly benefit from being written in asm to begin with, though. It's not like memcpy or strlen...Thanks. Twitter will use this to make your timeline better. UndoUndo

@RichFelker yeah, that makes a lot of sense. I assume it's in asm because direct futex syscall, but why not just inline that? -
@RichFelker first rule of asm coding is you only code in asm when needed, can't believe they'd violate that rule, wow. -
@bofh453 The first rule of being glibc's former maintainer is that you code asm whenever it enhances your job security.
