forked from Imagelibrary/binutils-gdb
Add support for the Imagination interAptiv MR2 MIPS32r3 processor with
the MIPS16e2 ASE as per documentation, including in particular:
1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
MIPS16e2 instructions[1], for assembly and disassembly,
2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
regular MIPS instructions[2], for assembly and disassembly,
3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
extension.
4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for
use e.g. with the `-m' command-line option for `objdump'.
Parts of this change by Matthew Fortune and Andrew Bennett.
