clang-3.8 fails to compile inline asm having ldarx with 4 args. Quoting [1]: ''' Recent versions of the PowerPC architecture added a hint bit to the larx instructions to differentiate between an atomic operation and a lock operation: > 0 Other programs might attempt to modify the word in storage addressed by EA > even if the subsequent Store Conditional succeeds. > > 1 Other programs will not attempt to modify the word in storage addressed by > EA until the program that has acquired the lock performs a subsequent > store releasing the lock. ''' I also found some more info about this in [2]. Anyway, we could either construct some preprocessor logic to omit this argument for clang, or just drop it. This patch does the latter.
