| last change | SH4 shadow-mode tweaks - Fix exceptions generated by the translator to account for the excepting instruction(s) in the cycle counts. - Compare floating point regs bitwise rather than with FP comparisons (otherwise can fail due to nan != nan) - Dump the translated block when we abort with an inconsistency |

| nkeynes@808 | 6 | ! instruction is only executed once. Note that we assume the exit actually |
| nkeynes@808 | 7 | ! takes place, but the mmu tests are unlikely to pass if it doesn't. |
