Brendan Punsky c6edd6d5cd rexcode/mips: R5900 MMI MADD/MSUB, RDPGPR/WRPGPR; drop BPOSGE64 -> 100%
PS2 R5900 MMI: MSUB1/MSUBU1 (second-MAC, SPECIAL2 func +0x20 exactly like
the implemented MADD1/MADDU1) and the three-operand MADD_EE/MADDU_EE/
MSUB_EE/MSUBU_EE (write Rd as well as HI/LO; the Rd!=0 form selected by a
less-specific mask after the two-operand MADD/MSUB and PLZCW match).
RDPGPR/WRPGPR (COP0 shadow-GPR move, hand-encoded from the MIPS32r2 manual
since llvm-mc gates them). Drop BPOSGE64: not a real ISA instruction
(DSPControl.pos is 6-bit, only BPOSGE32 exists; llvm rejects it).

Every encodable mips Mnemonic now has an encode form (gap = 0). All
self-consistent and decode-clean; 281 tests green.

The Data-Oriented Language for Sane Software Development.


The Odin Programming Language

Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.
