gcc uses trap 33 for profiling, but the simulator didn't support it.
This patch fixes the gcc.dg/nest.c failures for sh-elf.
Fri Oct 11 16:22:28 2002 J"orn Rennecke <joern.rennecke@superh.com>
* interp.c (trap): Return int. Take extra parameter for address
of the trap instruction. Changed all callers.
Add case 33 for profiling.
* gencode.c (trapa): Handle trap 33 using the trap function.
Add read of vector for generic traps.
