i386.c (ix86_function_arg_regno_p): Add MMX_REGNO_P for TARGET_MMX.
2005-06-16 Uros Bizjak <uros@kss-loka.si>
* config/i386/i386.c (ix86_function_arg_regno_p): Add MMX_REGNO_P
for TARGET_MMX. Use MMX_REGPARM_MAX and SSE_REGPARM_MAX for MMX
and SSE registers to determine if regno is valid.
(ix86_function_value_regno_p): Depend FIRST_FLOAT_REG on
TARGET_FLOAT_RETURNS_IN_80387 also for TARGET_64BIT. Clean up.
