Hi,
it turns out that the implementation of the PPC SYSV ABI in gcc still contains
a bug, float parameters passed on the stack are currently not promoted to
double. as specified in the ABI.
It seems using PROMOTE_MODE is not quite right here? I only want the promotion
if the args are passed on the stack.
Any ideas on how to tackle that?
Franz.
