Fix for Z80 retranslation post alignment rework
|
| Wed, 25 Nov 2015 08:40:45 -0800 |
Michael Pavone |
Partially working change to do proper stack alignment rather than doing a lame alignment check when calling a C compile dfunction. 68K core seems okay, but Z80 is busted.

Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).

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
