|
|
* Based on https://github.com/MicroCoreLabs/Projects/blob/master/MCL68/MC68000_Test_Code/MC68000_test_all_opcodes.X68
|
| 4 |
|
|
*
|
| 5 |
|
|
* Converted into a CD-i system ROM image by CD-i Fan:
|
| 6 |
|
|
* - comment lines must start in first column
|
| 7 |
|
|
* - replaced org instructions by suitable rept
|
| 8 |
|
|
* - copy vectors to low memory at startup
|
| 9 |
|
|
* - replaced jsr/jmp by bsr/bra for position independence
|
| 10 |
|
|
* - replaced move.l by moveq whenever possible
|
| 11 |
|
|
* - converted branches to short form whenever possible (e.g. beq => beq.s)
|
| 12 |
|
|
* - added immediate suffix to opcodes where required (e.g. and => andi)
|
| 13 |
|
|
* The last three modifications are required to make the test work;
|
| 14 |
|
|
* apparently the original assembler was somewhat smarter then
|
| 15 |
|
|
* the Microware OS-9 assembler and did this automatically.
|
| 16 |
|
|
*
|
| 17 |
|
|
* In some cases the opcodes of the test are used as test data!

* Description:

|
|
* ============
|
| 28 |
|
|
*
|
| 29 |
|
|
* Program to test all of the Motorola 68000's opcodes.
|
| 30 |
|
|
*
|
| 31 |
|
|
* If failures are detected, the code will immediately loop on itself.
|
| 32 |
|
|
* All addressing modes, data sizes, and opcode combinations are tested.
|
| 33 |
|
|
*
|
| 34 |
|
|
* This code was developed using the Easy68K simulator where all tests passed!
