Subject: (va_start): For stdarg, delete separate define for 64 bit ABI.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ba418aa40a65738e175e6e49ad5925a414b9fa8e;p=gcc.git

(va_start): For stdarg, delete separate define for 64 bit ABI.

(va_start): For stdarg, delete separate define for 64 bit ABI.  For
varargs, don't subtract 64, and only add -8 when all argument
registers are used.
