Fri, 07 Mar 2014 19:35:13 -0800 Michael Pavone Combine andi ccr/sr and ori ccr/sr.
Fri, 07 Mar 2014 17:51:40 -0800 Michael Pavone Use update_flags instead of individual set_flag calls in a few places
Fri, 07 Mar 2014 17:42:29 -0800 Michael Pavone Refactored translate_m68k so that it contains no host-cpu specific code and moved it to m68k_core.c
Wed, 05 Mar 2014 19:26:53 -0800 Michael Pavone Combine implementations of lea and pea. Update bit instructions to use the op_ family of functions to simplify their implementation a bit.

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
Sun, 02 Mar 2014 16:34:29 -0800 Michael Pavone 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 14:45:36 -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.

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 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, 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.
Sun, 16 Feb 2014 19:21:39 -0800 Michael Pavone Generate native_addr and native_addr_and_sync at runtime so they can use the generated save/load_context functions

Sat, 15 Feb 2014 21:25:36 -0800 Michael Pavone Generate m68k_start_context at runtime so it can use the generated load_context and save_context
Fri, 14 Feb 2014 19:56:18 -0800 Michael Pavone Generate save_context and load_context functions at runtime
