* cpu/sh: Fixed order of operands in disassembly of MAC.L (fixes MT09114). Vas Crabb2025-02-161-1/+1

* cpu/sh: Improved SH7021 SoC emulation. (#11610) [Ryan Holtz, Phil Bennett] Phil Bennett2023-10-161-15/+26
| | | | | * Added (rudimentary) SH7021 DMA, timers and GPIO, and logging for the rest. * Fixed SH2 NMIs occurring in a delay slot when using the interpreter. * Generally cleaned up code and renamed functions/macros/variables more conventionally.
* coretmpl.h: Add utility function for sign-extending values of arbitrary width AJR2022-11-011-8/+6
| | | | | * cpu/ccpu: Simplify code for right-shifting 12-bit values arithmetically * konami/3dom2_te.cpp: Fix probable copy-and-paste error
* Debugger feature improvements AJR2022-03-271-4/+4
| | | | | | | | - Add 'gbt' and 'gbf' debugger commands to step until a true or false conditional branch has been detected. - Update over 100 of the disassemblers in MAME to output a new STEP_COND flag for all conditional branches. Besides being used for execution of the new 'gbt' and 'gbf' commands, this flag also now helps the debugger 'out' command to properly handle conditional return instructions. - Remove STEP_OVER from many instructions that aren't actually subroutine calls (e.g. DJNZ on Z80). A 'gni' debugger command (go next instruction) has been added to accommodate some of the misuse. - Add instruction flag support to several more disassemblers that lacked them entirely (e.g. st62xx) - Don't pass over delay slots for debugging in ASAP core
* Make debugger 'out' command step over return delay slots on SH architectures AJR2021-09-221-4/+4

* dvdisasm: Overhaul [O. Galibert] Olivier Galibert2017-11-261-85/+87
| | | | | | | | Disassemblers are now independant classes. Not only the code is cleaner, but unidasm has access to all the cpu cores again. The interface to the disassembly method has changed from byte buffers to objects that give a result to read methods. This also adds support for lfsr and/or paged PCs.
