Assembler Testcases
|
||||||
|
===================
|
||||||
|
|
||||||
|
These testcases are inspired by the ones now removed from test/assembler.
|
||||||
|
The main purpose is to have each possible opcode generated at least once,
|
||||||
|
either by an assembly instruction or a ".byte"-placeholder. Typically
|
||||||
|
generated by disassembling a binary dump that contains data in the form
|
||||||
|
of the pattern that each opcode is stated once in order followed by easy
|
||||||
|
to recognise:
|
||||||
|
|
||||||
|
00 00 EA 00
|
||||||
|
01 00 EA 00
|
||||||
|
02 00 EA 00
|
||||||
|
[...]
|
||||||
|
fe 00 EA 00
|
||||||
|
ff 00 EA 00
|
||||||
|
|
||||||
|
The disassembly is then put in a better readable form by replacing the
|
||||||
|
leftover dummy opcode parameters with something more recognizable.
|
||||||
|
|
||||||
|
The testcases for 6502, 6502x, 65sc02, 65c02, 4510, and huc6280 have been
|
||||||
|
put together by Sven Oliver ("SvOlli") Moll, as well as a template for the
|
||||||
|
m740 instructions set.
|
||||||
|
|
||||||
|
Still to do is to find a way to implement a testcase for the 65816
|
||||||
|
processor, since it's capable of executing instructions with an 8-bit and
|
||||||
|
a 16-bit operator alike, only distinguished by one processor flag.
