Re: [patch] GAS supports for MIPS32 MT ASE

["Chao-ying Fu" <fu at mips dot com>]

Hello,

  Here is the latest patch with the change: -mmt/-mno-mt.
Also, "mips32-mt.d" is changed to use "-mmt".
I built and tested for mipsisa32-elf and mipsisa64-elf.  No
new regression.  Any comments?  Thanks!

Regards,
Chao-ying
