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	stop relying on mmio for behavior validation	iximeow
	first, the vcpu is configured with 1G pages, which confound linux's gva->gpa translation done as part of instruction emulation. this means that we get bogus faults in perfectly valid virtual addresses that the hardware can use, but linux cannot. second, relying on mmio means every mmio-trapped instruction is actually testing yaxpeax-x86 semantics against linux x86 emulation. while this is interesting, it is not the goal of the tests. maybe some later day! finally, write_matches_reg() had an inappropriate mask for what bits can be written given a certain register size.
2026-03-02	this might actually work omggggg	iximeow

2026-03-02	cleanup, document, etc	iximeow

2026-03-02	ok, gdt works... (mem16:32 means 32-bit offset THEN 16-bit selector???)	iximeow

2026-02-23	set up an IDT, and try to use it, but just discover the GDT is actually broken	iximeow
	also shrink the GDT to 256 entries because i really won't use 8k of them. this makes the GDT entries only 0x400 bytes but i still skip a page from gdt_addr() to idt_addr().
2026-02-23	more expansive access behavior validation, start on implicit op lists	iximeow

2026-02-23	if tripped over a kvm bug i swear	iximeow

2026-02-23	cleanup	iximeow

2026-02-23	more reworking of vm and test harness	iximeow

2026-02-23	lmao this rules	iximeow
