Good spot. Looks like you could do the same thing with -mabi=64, but it isn't as logical as the mips16/micromips thing and probably wouldn't win much. > I also make the new mnan=2008 flag exclusive of msoft-float since it > is only useful for hard-float. Well, it's useful for both, because -msoft-float uses the same NaN format as -mhard-float. But not having the multilib is fine. > 2013-08-07 Steve Ellcey <sell...@mips.com> > > * config/mips/mti-linux.h (SYSROOT_SUFFIX_SPEC): Add nan2008. > * config/mips/t-mti-elf (MULTILIB_OPTIONS): Make mips16 and > micromips incompatible.
