This series amends the R5900 support with the following noncritical
features:
- The vendor-specific Application-Specific Extension (ASE) ASE_MMI is
renamed to ASE_TOSHIBA_MMI, because several vendors have multimedia
instruction (MMI) sets and other extensions of various kinds. ASE
vendor namespaces make it clear these are not generic architectural
features and also avoid name clashes.
- The R5900 LQ and SQ instructions are now also covered by the Toshiba
MMI ASE, as per the TX79 manual[1].
- The three-operand MADD and MADDU instructions specific to the R5900
and the Toshiba TX19, TX39 and TX79 cores are now supported and tested
by the R5900 TCG test suite.
- The three-operand MADD1 and MADDU1 pipeline 1 instructions specific
to the R5900 and the Toshiba TX79 core are now supported and tested
by the R5900 TCG test suite.
- The membership field of struct mips_opcode is now uint64_t instead
of unsigned long, that is too small in 32-bit builds.
- R5900 disassembly constants are defined.
- The R5900 instructions DIV1, DIVU1, MFLO, MTLO, MFHI, MTHI, MULT1 and
MULTU1 are now disassembled. Unfortunately, the opcodes for MADD1 and
MADDU1 clash with the opcodes for CLZ and CLO, resulting in incorrect
disassembly. MADD1 and MADDU1 are therefore left undefined.
This series has been successfully built with the 16 different build
configurations
{gcc,clang} x -m{32,64} x mips{,64}el-{linux-user,softmmu}
in addition to successfully completing the R5900 test suite
cd tests/tcg/mips/mipsr5900 && make check
