SSP support for gcc on mips?

SSP support for gcc on mips?

Hi

I'm working with gcc-4.3.4  uclibc-0.9.30.1-r1 on a mips system. 
(32-bit big endian abi=o32).

I'd like to get ssp, but -fstack-protector leads to

foo.c:1: warning: -fstack-protector not supported for this target

I traced it back and there simply isn't any ssp support in gcc for
mips.  Ironically uclibc does have __stack_chk_fail.

Can anyone shed light on this?  What's the status of ssp on mips?

-fstack-protector should work for MIPS targets in the upcoming gcc 4.5
release.  In current releases it does not work.  Sorry.
