* Implement EXT instruction used in GLIBC startup.Pavel Pisa2019-02-15
| | | | | | It requires one more field to pass to ALU. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>

* Add license to the source files.Pavel Pisa2019-02-04

* Implement BREAK instruction to stop continuous execution.Pavel Pisa2019-02-03
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Implement instructions MULT, MULTU, DIV, DIVU.Pavel Pisa2019-02-03
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Include support for JALR support.Pavel Pisa2019-01-31
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Initial support for JAL.Pavel Pisa2019-01-31
| | | | | | | The JR, BEQ, BNE are most probably incorrect still. There is missing forwarding for pipelined execution. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Correct signed arithmetic overflow exception.Pavel Pisa2019-01-31
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Implement LUIKarel Kočí2018-04-08
|
* Cleanup some todos in codeKarel Kočí2018-01-15
|
* Fix SRA and SRAV instructionsKarel Kočí2018-01-15
| | | | | | This implementation is correct one but there is no guarantee that it will work with all compilers so we should always check on given platform that tests pass (and potentially fix it).
* Fix fall trough warning of gcc 7+Karel Kočí2018-01-05
|
* Initial implementation of reverse instruction conversionKarel Kočí2018-01-03
| | | | | | This is rude implementation. We always print all fields. In future we should add flags to set what fields should be hidden on per instruction bases.
* Put qtmips_machine to machine namespaceKarel Kočí2017-12-17
|
* Revert "Suppress some warning"Karel Kočí2017-12-17
| | | | This reverts commit 5bf637a429bbcf09092b8d189010c50d61c3562f.
* Implement branch and jump instructionsKarel Kočí2017-12-12
|
* Suppress some warningKarel Kočí2017-12-12
| | | | | You can call it a fix but in reality it has same effect but I accept that this is better.
* Add crude implementation of MOV* instructionsKarel Kočí2017-11-25
| | | | I don't like how it's implemented but I have no other idea atm.
* Implement instructions for moving from and to HI and LO registersKarel Kočí2017-11-25
|
* Fix SLTU instructionKarel Kočí2017-11-25
|
* Implement tests for few more arithmetic instructionsKarel Kočí2017-11-21
|
* Another huge pile of work for about two monthsKarel Kočí2017-11-19
| | | | | | Well I should commit every change instead of this madness. I am not documenting changes as all this is just improvements and implementation progression.
* Just something I had staggedKarel Kočí2017-11-19
