Adds (rebased onto the .ew refactor, opcode 0101011): - mcmpeq.ew / mcmpne.ew (elementwise == / != compares) - mrec.ew / msqrt.ew / mrsqrt.ew / mtanh.ew (SFU estimates, new "Special Functions" group) - mmov.m.a (M register -> accumulator move; mirror of mmov.a.m) and the corresponding AmeOperation enum members (CMPEQ1D..TANH1D). funct7 36-42 (previously free). The redundant mul/FMA instructions from the earlier draft were dropped in favor of upstream mmul.ew/mmulacc.ew/etc. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Adds 7 instructions to the Attached Matrix Extension (Zvame), rebased onto the recent
.ewrefactor (opcode0101011):Compare and Predication
mcmpeq.ew— elementwise equality (IEEE 754-2008 OEQ; NaN → false)mcmpne.ew— elementwise inequality (IEEE 754-2008 UNE; logical complement ofmcmpeq.ew)Special Functions (new group)
mrec.ew— reciprocal estimatemsqrt.ew— square-root estimatemrsqrt.ew— reciprocal-square-root estimatemtanh.ew— hyperbolic-tangent estimateState Management
mmov.m.a— move M register group → accumulator (mirror ofmmov.a.m)Encodings use opcode
0101011, funct7 36–42 (previously free); verified no encoding conflicts across the extension. Adds the correspondingAmeOperationenum members (CMPEQ1D..TANH1D).Notes:
ame_opcompute branches for the new ops are not yet implemented (consistent with existing draft ops likeEXP21D);operation()bodies follow themadd.ew/mexp2.ew/mmov.a.mpatterns.🤖 Generated with Claude Code
