Maciej W. Rozycki 11a3799dbe MIPS: Fix unaligned PC interpretation in `compute_return_epc' ... Fix a regression introduced with commit fb6883e580 ("MIPS: microMIPS: Support handling of delay slots.") and defer to `__compute_return_epc' if the ISA bit is set in EPC with non-MIPS16, non-microMIPS hardware, which will then arrange for a SIGBUS due to an unaligned instruction reference. Returning EPC here is never correct as the API defines this function's result to be either a negative error code on failure or one of 0 and BRANCH_LIKELY_TAKEN on success.
