* NEWS: Mention microMIPS XPA support.
opcodes/
* micromips-opc.c (XPA, XPAVZ): New macros.
(micromips_opcodes): Add "mfhc0", "mfhgc0", "mthc0" and
"mthgc0".
gas/
* config/tc-mips.c (mips_ases): Add microMIPS XPA support.
* testsuite/gas/mips/micromips@xpa.d: New test.
* testsuite/gas/mips/mips.exp: Run the new test. Enable
`xpa-virt-err' test for `micromips'.
