Re: fold_truthop patch causes sparcv9 testsuite regressions

Just out of curiosity, does this fix any other GCC test suite failures
using "-m64" on sparc*-sun-solaris*? I'd have thought that the recent
20000511-1.c failure caused by my optimization is only the tip of the
iceberg.
No, it doesn't. How much code computes the modulo of constant zero on
purpose? :-) That is the condition necessary for this to trigger.
If one likes, one could add a "int foo(int x) { return x % 0; }" to
gcc.dg to make sure this bug doesn't come back. Be mindful to ignore
the warnings properly :-)
