MIPS/opcodes: Disassemble the RFE instruction
Fix a commit b015e599c772 ("[MIPS] Add new virtualization instructions"),
<https://sourceware.org/ml/binutils/2013-05/msg00118.html>, regression
and bring the disassembly of the RFE instruction back for the relevant
ISA levels.
It is because the "rfe" opcode table entry was incorrectly moved behind
the catch-all generic "c0" entry for CP0 instructions, causing output
like:
00: 42000010 c0 0x10
to be produced rather than:
00: 42000010 rfe
even for ISA levels that do include the RFE instruction.
Move the "rfe" entry ahead of "c0" then, correcting the problem. Add a
suitable test case.
opcodes/
* mips-opc.c (mips_builtin_opcodes): Move the "rfe" entry ahead
of "c0".
gas/
* testsuite/gas/mips/rfe.d: New test.
* testsuite/gas/mips/rfe.s: New test source.
* testsuite/gas/mips/mips.exp: Run the new test.
