There are additional problems with these tests and I don't have
time to finish looking at them today, but here's some info.

Using a recent 4.0 CVS:
gcc version 4.0.0 20050412 (prerelease)
Compiling the following as 64bit:
unsigned int foo(unsigned int x)
{
return ((x 16) 0x) | ((x 0x) 16);
}
Results in:
.L.foo:
slwi 0,3,16
srwi 3,3,16
or 3,3,0

Fails for cris-elf and mmix-knuth-mmixware as well. Timespan that narrows down
the suspects a little: worked on LAST_UPDATED Tue Apr 12 20:48:11 UTC 2005,
started failing Wed Apr 13 05:00:11 UTC 2005.

Actually, we can and should fix this. What I gave was only a workaround.

;; Function foo (foo)
;; enabled by -tree-original

return (int) __builtin_lceilf (x);
}
These functions (lceil and lfloor) share the same

I susupect the bug to be in expand_builtin_int_roundingfn(). It looks that
tmp = gen_reg_rtx(floatmode);
is needed before
tmp = expand_builtin_mathfn (exp, NULL_RTX, NULL_RTX);
It is somehow annoying fact
