* cpu/cr16b, cpu/es5510, cpu/ks0164, cpu/mb86235, cpu/sharc, upd7220: Use ↵ AJR2022-11-011-9/+6
| | | | | | util::sext and other bit utility functions * cpu/sharc: Be a bit more paranoid about extreme values of bit6 and len6 (non-DRC)
* Debugger feature improvements AJR2022-03-271-2/+13
| | | | | | | | - 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
* Reshuffle some stuff: Vas Crabb2018-03-281-1/+4
| | | | | | * Move around the debugger hooks to get a small but measurable performance increase * Remove emucore from external tools * Improve performance of DSP16 interpreter a little by generating six variants of execution loop
* dvdisasm: Overhaul [O. Galibert] Olivier Galibert2017-11-261-372/+392
| | | | | | | | 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.
* Removing 'sharc_dasm_one(char *buffer, ...' Nathan Woods2016-11-201-13/+1

* Changed disassembler infrastructure to not use char buffers internally Nathan Woods2016-11-201-0/+2

* Introduce u8/u16/u32/u64/s8/s16/s32/s64 Vas Crabb2016-11-191-9/+9
| | | | | | | | | | | | * New abbreviated types are in osd and util namespaces, and also in global namespace for things that #include "emu.h" * Get rid of import of cstdint types to global namespace (C99 does this anyway) * Remove the cstdint types from everything in emu * Get rid of U64/S64 macros * Fix a bug in dps16 caused by incorrect use of macro * Fix debugcon not checking for "do " prefix case-insensitively * Fix a lot of messed up tabulation * More constexpr * Fix up many __names
* Changed the sharc disassembler to use 'std::ostream &' internally Nathan Woods2016-11-171-3/+13

* NOTICE (TYPE NAME CONSOLIDATION) Miodrag Milanovic2016-10-221-46/+46
| | | | | Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8 also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
