5 days
docs, cleanup
inst-behavior
iximeow
5 days
adjust test framework to support complex ops, some other cleanup
iximeow
also fix swapped BehaviorDigest order. that's scary..
6 days
behavior feature, also shrink 40kb from behavior additions
iximeow
6 days
so much more docs
iximeow
9 days
add behavior fuzzing, fix some stuff it noticed
iximeow
12 days
the rest of x86-64 behaviors. so far.
iximeow
2026-05-08
vex support done, starting on evex..
iximeow
2026-05-03
much closer to comprehensively covering vex instructions..
iximeow
2026-04-23
start verifying vex-encoded instruction behavior
iximeow
2026-04-19
a few more straggler instructions
iximeow
2026-04-19
the rest of sse?
iximeow
2026-04-19
substantially more sse coverage
iximeow
2026-04-12
cmovcc: encode operand 2 correctly
iximeow
2026-04-12
check and support more 0fXX opcodes
iximeow
2026-04-12
test table management instructions ({l,s}{g,i,l}dt)
iximeow
these instructions, it turns out, have fixed operand size based on CPU execution mode and regardless of prefixes. good to know!
2026-04-12
many conditional instructions, jump, call, and start testing 0f opcodes
iximeow
2026-03-28
more behavior, the rest of two-byte instructions?
iximeow
2026-03-27
div ops, mul ops, some other
iximeow
2026-03-19
more instructions, figured out mul/imul
iximeow
2026-03-09
back at it with more instruction behaviors and carveouts
iximeow
2026-03-09
api and more inst behavior
iximeow
2026-03-09
write/read writes operand 0
iximeow
2026-03-09
exception vector fmt
iximeow
2026-03-02
this might actually work omggggg
iximeow
2026-02-23
more expansive access behavior validation, start on implicit op lists
iximeow
2026-02-23
visit flags changes, tests caught a bug!
