[ gas/ChangeLog ] * config/tc-mips.c (macro_build): Test for currently active mips16 option. (mips16_ip): Reject invalid opcodes. [ opcodes/ChangeLog ] * mips16-opc.c (I1, I32, I64): New shortcut defines. (mips16_opcodes): Change membership of instructions to their lowest baseline ISA. [ gas/testsuite/ChangeLog ] * gas/mips/mips.exp: Run new tests. * gas/mips/mips16e.s, gas/mips/mips16e.d, gas/mips/mips16e-64.s, gas/mips/mips16e-64.d, gas/mips/mips16e-64.l: New tests.
