MIPS16/opcodes: Respect ISA and ASE in disassembly
Limit MIPS16 instruction disassembly according to the ISA level and ASE
set selected, as with the regular MIPS and microMIPS instruction sets.
Retain the property of `objdump -m mips:16' disassembling all MIPS16
instructions however, regardless of any ISA level recorded in the binary
examined.
To validate the disassembler use the GAS test suite for its convenience
of running tests across multiple ISAs, even though placing the tests in
the binutils test suite would be more appropriate. Adjust the single
binutils test which depends on 64-bit instruction disassembly to have
the ISA level required actually recorded in the binary examined.
opcodes/
* mips-dis.c (mips_arch_choices): Use ISA_MIPS64 rather than
ISA_MIPS3 as the `isa' selection in the `bfd_mach_mips16' entry.
(print_insn_mips16): Check opcode entries for validity against
the ISA level and ASE set selected.
binutils/
* testsuite/binutils-all/mips/mips16-undecoded.s: Use `.module'
rather than `.set' to set the ISA level.
