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
Mon, 23 Jun 2014 11:05:55 -0400, by Mike Pavone
blastem builds and almost works on OS X now
Tue, 17 Jun 2014 01:50:29 -0400, by 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 01:30:16 -0800, by Mike Pavone
Rename x86_backend.h and x86_backend.c to backend.h and backend.c respectively

Mon, 24 Feb 2014 00:40:32 -0800, by Michael Pavone
Start work on refactoring some of the backend code to allow more sharing between M68K and Z80 cores and possibly also between x86 and the ARM backend when it exists

Generate get_sr, set_sr and set_ccr at runtime so they can respect the flag_regs setting
Tue, 18 Feb 2014 20:32:10 -0800, by 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.
Mon, 17 Feb 2014 19:58:37 -0800, by Michael Pavone

Sun, 16 Feb 2014 16:50:10 -0800, by Michael Pavone
Get rid of the native stack option the 68K core. Trying to make it work with code that messes with the stack is not worth the trouble.

Tue, 11 Feb 2014 12:45:15 -0800, by Michael Pavone
Added step and step-over debugger commands. step-over is like next except it doesn't follow conditional branches to lower addresses. This makes it useful for advancing to the end of a loop. Also fixed a bug in next introduced by the refactor.

Thu, 06 Feb 2014 10:03:59 -0800, by Michael Pavone
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.
Mon, 03 Feb 2014 09:18:10 -0800, by Michael Pavone
Add 3 wait states to Z80 access to bank area since that seems to be roughly the average in normal usage

Implement funny behavior for DMA fill to CRAM and VSRAM. Return VSRAM address 0 for reads to VSRAM at >= 40
Tue, 17 Sep 2013 00:42:49 -0700, by Mike Pavone
Fix DMA fill so that it does not cause observable changes to the FIFO. Get DMA copy mostly correct from an observable ffect perspective. DMA copy probably does not reflect internal implementation still given that evidence seems to suggest no FIFO usage at all.
