Hi Faraz,
> Add support for the Global INValidate Application Specific Extension
> for Release 6 of the MIPS Architecture.
I have fixed a small number of issues, most notably reordered the
handling of the `-M ginv' in `parse_mips_ase_option' to match the order
used elsewhere, and also a ChangeLog entry for the NEWS update in gas/ was
missing (I also fixed the ChangeLog entry similarly for the CRC ASE
support previously committed). No issues in regression testing. Here's
the final version I have committed.
Thank you for your contribution.
Maciej
