This appears to be sufficient for the Electron to _read_ SCSI.
...
So that's step one.

Better sorts by function, corrects TEST description.
2021-01-15 21:07:02 -05:00
47d20699d8
Completes list, ensures POP acts as documented.
2021-01-15 20:48:31 -05:00

2021-01-13 21:51:18 -05:00
8c0e06e645
Adds a test for 0x83 and fixes sign extension.
...
ODA doesn't seem to accept 0x82, but testing 0x83 adds some confidence.
2021-01-13 20:42:21 -05:00
a24ae727a7
Takes a run at 0x82 and 0x83, completing the set.
2021-01-13 20:29:44 -05:00

Completes the first test stream.
...
... and improves decoding consistency in conjunction.
2021-01-12 21:49:22 -05:00
762ecab3aa
Adds operand/displacement capture.
...
This gets unit test as far as a disagreement over how to handle bad 0xc4 suffixes.
2021-01-10 22:55:25 -05:00
9ba5b7c1d4
Adds a few more asserts.
...
It's still just operands and displacements failing, which is nice.
2021-01-08 23:21:01 -05:00
5f807b6e47
Ensures that the operand is the only thing failing in decoding of the first instruction.
2021-01-08 23:02:06 -05:00

2021-01-08 22:38:56 -05:00
86577b772b
Rethinks size; packs all captured information into an x86 Instruction.
...
Albeit that operand and displacement are't yet captured. Or extractable.
2021-01-08 22:22:07 -05:00
306df7554e
Starts trying to find a good packing for X86 instructions.
...
To consider: do I really need `size` on every instruction?

Attempts to complete operand recognition.

Fills in 8f, c2, c3, ca and cb.
...
Also switches to RETN and RETF for near/far RET as this seems idiomatic.
2021-01-06 21:18:24 -05:00
17cbba85fc
Formalises what's missing in terms of opcodes and fills in some blanks.
2021-01-05 21:47:12 -05:00
9d7d45338f
Ostensibly gets the instruction stream correct for test case 1.
...
Subject to operand and displacement currently being absent, and likely inconsistencies in field population, most of which are omitted from the Instruction anyway.
2021-01-05 21:34:35 -05:00

Nudges up to a need to decode operation from the ModRegRM byte.
