Hello
I'm trying to run gcc from spec2k under SPARC_SE and ran into a few
unimplemented syscalls. Attached is a patch that enables getrlimit and
getrusage and sets setrlimit to be ignored.
The code is modeled on the Alpha code and seems to work. gcc.spec2k still
doesn't work though. On expr it makes it about 1/3 the way through and
then fails out due to an illegal memory access.
