* 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>
* Correct shift operation and make ALU_OP_MOVZ and ALU_OP_MOVN encoding ↵Pavel Pisa2019-02-05

* Unified instructions table and access type move to machinedefs.h .Pavel Pisa2019-02-04
| | | | | | | This allows to specify requirement for RS and RD on instruction basis even for T_R / ALU instructions. 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

* 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>
* Implement LUIKarel Kočí2018-04-08

* Cleanup some todos in codeKarel Kočí2018-01-15
|
* 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
|
* Tiny cleanupKarel Kočí2017-12-12
|
* Implement branch and jump instructionsKarel Kočí2017-12-12
|
* 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
|
* Add possibility to compare memory and registers stateKarel Kočí2017-11-21
| | | | | | For core testing we want to compare whole memory and registers. Registers are pretty simple but in case of memory it is some what more complicated and required its own tests to be sure that it works.
* 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
