Subject: MIPS: Use 64-bit a ABI by default for `mipsisa64*-*-linux*' targets
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=025e84f93566c8ced594ef48ddee1dec7e5b4cdd;p=binutils-gdb.git

MIPS: Use 64-bit a ABI by default for `mipsisa64*-*-linux*' targets

Following the arrangement in GCC select a 64-bit ABI by default, either
n32 or n64, rather than o32 for `mipsisa64*-*-linux*' targets, just as
with the corresponding `mips64*-*-linux*' targets.
