More 68K core refactoring to both reduce the amount of code and better split the host-cpu specific parts from the generic parts
|
| Mon, 03 Mar 2014 22:16:41 -0800 |
Michael Pavone |
Enable link time optimization
|
| Mon, 03 Mar 2014 21:08:43 -0800 |
Michael Pavone |
Make some small changes in trans so that it is more likely to produce the same output as mustrans when given misbehaving programs. Add lea to testcases.txt. Improve the output of comparetest.py so that known issues can easily be separated from new ones.
|
| Sun, 02 Mar 2014 17:53:32 -0800 |
Michael Pavone |
Refactor translat_m68k_src and translate_m68k_dst into a single function

Initial stab at separating the generic parts of the 68K core from the host-cpu specific parts.
|
| Sun, 02 Mar 2014 15:25:52 -0800 |
Michael Pavone |
Rename x86_68k_options and m68k_to_x86.h to m68k_options and m68k_core.h respectively
|
| Sun, 02 Mar 2014 14:46:55 -0800 |
Michael Pavone |
Small Makefile change that was missed in the last commit
|
| Sun, 02 Mar 2014 14:45:36 -0800 |
Michael Pavone |
Refactor gen_x86 to use an interface more like gen_arm and to remove the need for the caller to decide whether an 8-bit or 32-bit displacement is needed in the rdisp functions. Update m68k_to_x86 to use the new version of the gen_x86 functions and do some minor refactoring there in the process
|
| Sun, 02 Mar 2014 14:41:43 -0800 |
Michael Pavone |
Add backtrace (bt) command to 68K debugger
|

| Mon, 24 Feb 2014 09:55:24 -0800 |
Michael Pavone |
Moved some generic stuff from backend.h gen_arm.h and gen_arm.c into gen.h and gen.c. Added a couple fields to cpu_options so that gen_mem_fun can be made guest CPU generic
|
| Mon, 23 Jun 2014 13:12:04 -0400 |
Mike Pavone |
Ensure proper stack alignment when the Z80 calls into C code. This fixes a crash in optimized builds on OSX
|
| Mon, 23 Jun 2014 11:46:56 -0400 |
Mike Pavone |
Save and restore guest address in the write function for a code memory chunk in the "slow" path for inconvenient host addresses. This fixes an intermittent crash on OSX in the code that checks whether the memory written may contain code
|
| Mon, 23 Jun 2014 11:05:55 -0400 |
Mike Pavone |
Fix x86_rrindex_sizedir. Pass the correct scale to mov_rindexr in gen_mem_fun. BlastEm now sort of works on OS X. Runs reliably from lldb, but only intermittently from the shell
|
| Tue, 17 Jun 2014 01:50:29 -0400 |
Mike Pavone |
blastem builds and almost works on OS X now
|
| Mon, 24 Feb 2014 01:30:16 -0800 |
Mike Pavone |
Use a typedef code_ptr in place of uint8_t * in 68K core to better support host instruction sets with different instruction word sizes. Make x86_68k_options contain a cpu_options so that gen_mem_fun can eventually be shared with the Z80 core.
|
| Mon, 24 Feb 2014 00:50:15 -0800 |
Mike Pavone |
Rename x86_backend.h and x86_backend.c to backend.h and backend.c respectively

Generate get_sr, set_sr and set_ccr at runtime so they can respect the flag_regs setting
|
| Mon, 17 Feb 2014 19:58:37 -0800 |
Michael Pavone |
Make references to flags in the M68K core respect the flag_regs options array so that flags can be moved out of registers for the 32-bit port. set/get ccr/sr still need to be updated to support this, but everything else should be done.
|
| Sun, 16 Feb 2014 19:54:27 -0800 |
Michael Pavone |
Generate handle_cycle_limit at runtime so it can use the generated save/load_context functions. Since the hand written versions of save/load are no longer used they have been removed.

Initial attempt at emulating extended bank area access delays when 68K bus is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.
