Joern Rennecke	fd8f4948fe	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.	24 years ago
