Subject: (SETUP_INCOMING_VARARGS): In if statement, only subtract one for stdarg.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=48eebadec0143fb1cd2c717470c54cffca36f229;p=gcc.git

(SETUP_INCOMING_VARARGS): In if statement, only subtract one for stdarg.

(SETUP_INCOMING_VARARGS): In if statement, only subtract one for
stdarg.  Don't subtract PRETEND_SIZE from argument pointer when
calculating stack address.
