Description
The fix for 6990212 included making the raiseException path do a normal dispatch instead of always using the compiler entry.  The assembly for 64 bit had a few minor breakages.  The code should be passed as an int instead of a ptr and on x86 the saved sp register is wrong.

EVALUATION 7075623: 6990212 broke raiseException in 64 bit Reviewed-by: kvn, twisti The fix for 6990212 included making the raiseException path do a normal dispatch instead of always using the compiler entry. The assembly for 64 bit had a few issues. On x86 the saved sp register is wrong which causes rarg0_code to be killed. On sparc the code should be passed as an int instead of a ptr which causes problems because of endianness. I also modified the x86 code to do the same. Tested with original regression test on sparc/x86 32/64 -Xcomp/-Xmixed. I also reran the failing JDK regression tests.
