Rafael Espindola 84716579d4 Fix va_arg for doubles. With this patch VAARG nodes always contain the correct alignment information, which simplifies ExpandRes_VAARG a bit. The patch introduces a new alignment information to TargetLoweringInfo. This is needed since the two natural candidates cannot be used: * The 's' in target data: If this is set to the minimal alignment of any argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for example. * The getTransientStackAlignment method. It is possible for an architecture to have argument less aligned than what we maintain the stack pointer. llvm-svn: 108072	2010-07-11 04:01:49 +00:00
