* Allow spaces in middle of assembler arguments and report errors.Pavel Pisa2019-07-03
| | | | Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Change instruction parsing to allow multiple words pseudo-operations.Pavel Pisa2019-07-02

* Minimal prototype of integrated assembler.Pavel Pisa2019-07-01
| | | | | | | The labels are parsed and stored into symbol table but expressions dependent on symbols values are not evaluated. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Memory change counter moved to MemoryAccess and external changes ↵Pavel Pisa2019-06-30
| | | | | | | | | | | notification added. This change together with use of PhysAddrSpace as the memory content source for memory and program view allows to access and monitor contents of peripheral registers and frame-buffer memory from graphic user interface.

* Fix nested calls of setCurrentIndex which caused breakage.Pavel Pisa2019-03-14
| | | | | | | | | | | | | | | | | ProgramTableView::focus_address() calls QAbstractItemView::setCurrentIndex(). verticalScrollBar() value is updated as result of current row change. This emits signal valueChanged which is connected to ProgramTableView::adjust_scroll_pos(). It checks if the limit of range covered by actual model and row to address offset is reached. If the top or bottom 1/8 of range is reached then model needs to be adjusted to cover continuation area. Model shift requires update of the current row to stay on the same address even that row 0 address offset is changed. This model shifting is required because range of scroll is only signed integer and QTableView is even more limited in row count to work reliably. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Complete revamp of disassembler and assembler arguments processing.Pavel Pisa2019-03-05
| | | | | | | | | | | | | | | | | | | | | Instructions description in instruction.cpp has been pragmatically augmented by tool based on Python MIPS simulator, hazards analyzer https://github.com/ppisa/apo-simarch That code has been originally distilled from from GNU binutils sources. Implementation is now inline with my original proposal Previous solution gets untenable with more complex instructions and its complexity would grow extremely. MIPS instruction set with coprocessor instructions which use sel field, rd used as index, rt as destination and other peculiarities in newer versions cannot be processed based on basic CPU control signals.

* Make memory and program listing editable.Pavel Pisa2019-02-12
| | | | | | Instruction parsing is rough and does not support branch offset computation. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Basic "hardware" breakpoints support implemented.Pavel Pisa2019-02-11
| | | | | | | | | | It works like real inserted breakpoint on hardware. Breakpoint has to be removed to allow code continue because else instruction is refetch and breakpoint triggers again. The single step function should resolve temporal masking of the breakpoint. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* Extend program view to support selected stage followup.Pavel Pisa2019-02-11

* Converted program listing to be QTableView based.Pavel Pisa2019-02-11
