* 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.

* Disable text elide for memory and program views.Pavel Pisa2019-06-05
| | | | | | | | | | Set of Monospace font does not ensure that different hexadecimal numbers do not vary in in the text size on MAC OS. QFontDatabase::systemFont(QFontDatabase::FixedFont) works on MAC OS but selected font looks ugly. Disable elide ensures that most of the text is seen.

* Change single cycle core with delay slot to use separate fetch stage.Pavel Pisa2019-03-26
| | | | | | | | | | | | When instructions are visualized then it is even more misleading to keep old instruction in decode phase delay buffer. The single cycle core with delay slot is upgraded to the variant with fetch and execute phases. This way the structure is logical and delay slot has purpose.

* Switch to static libraries by default and ensure application rebuild when a ↵Pavel Pisa2019-03-15
| | | | | | | | | | | | | | | | library changes. I have not found a way how to pass additional CONFIG options to Debian package build (dpkg-buildpackage) when qmake is invoked from debian/rules with debian helper based (dh) build. The way how qmake solves dependencies between program and libraries comes from stone age. It is necessary to include complete path to the library in PRE_TARGETDEPS definition including lib prefix and .a suffix. This is non portable and cannot be easily used when static and dynamic libraries build alternatives are considered. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz>
* More precise program and memory tableviews column width calculation.Pavel Pisa2019-03-15

* 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>

| | | | | | | | | | | option. When operating system emulation root directory (fs_root) are selected then open() syscall opens real host system files in this limited subtree. When fs_root is not set then console is mapped to all read, write, open and close calls. 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.
