comparison m68k_to_x86.h @ 558:dc9f178085a0

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
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.
