-fstack-check works?

["William A. Gatliff" <bgat at billgatliff dot com>]

Guys:


Does -fstack-check work for targets like arm-elf?

A quick compilation of "hello, world" didn't turn up anything
obviously different in the main() implementation with -fstack-check
turned on or off, although the two images were different according to
a diff on the disassembled images.

If -fstack-check does work, what happens when the check fails?  Er,
what does gcc's checking code do when the check fails, assuming the
system is still running... :^)


Thanks!
