| last change | Setup a 'proper' stackframe in translated blocks. This doesn't affect performance noticeably, but does ensure that a) The stack is aligned correctly on OS X with no extra effort, and b) We can't mess up the stack and crash that way anymore. Replace all PUSH/POP instructions (outside of prologue/epilogue) with ESP-rel moves to stack local variables. Finally merge ia32mac and ia32abi together, since they're pretty much the same now anyway (and thereby simplifying maintenance a good deal) |

1 SH4 instruction set tests.
2 Each core instruction has its own set of tests that are assembled into the
3 main test executable.
5 Note: Since each instruction's tests obviously depends on other
6 instructions, its possible for multiple bugs to cancel each other out.
7 However the tests are structured as much as possible to prevent this.
9 Each test loops repeatedly for a constant number of times (currently 1000)
10 to a) ensure that dynamic recompilation kicks in and recompiles the block,
11 and b) allow the code to be timed (to a first approximation anyway).
