| * | Display red background for instruction causing exception and skip HW ↵ | Pavel Pisa | 2019-02-11 |
| | | | | | | | | | | | breakpoint for first cycle after resume. Instruction for stage is updated when given stage is flushed as well.

| * | Basic "hardware" breakpoints support implemented. | Pavel Pisa | 2019-02-11 |
| | | | | | | | | | | | 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> | ||
