Absolute 0 assumed. /var/tmp/cczbJSUe.s:1993:operands given don't match any known 386 instruction The code in it is complaining about is an inline cmpxchgl asm routine: static inline uint32_t my__cmpswap_u32(uint32_t *ptr, uint32_t old, uint32_t new) { asm volatile("lock cmpxchgl %1,%2" : "=a" (old) : "q" (new), "m" (*ptr),"0" (old) : "memory"); return old; } Our assembler doesn't accept "lock" as a valid prefix byte. This came up at a WWDC lab too; adding newline is a workaround, but it's reasonable to expect that the assembler does what everybody else's assembler can do, so please file a bug also.
