Subject: MIPS: Default to --with-llsc for the R5900 Linux target as well
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=240ae287a189d21ea15c93bba1f774ee69e673a7;p=gcc.git

MIPS: Default to --with-llsc for the R5900 Linux target as well

The Linux kernel requires and emulates LL and SC for the R5900 too.  The
special --without-llsc default for the R5900 is therefore not applicable
in that case.
