The attached patch fixes the failures on m68k-suse-linux, visium-elf,
and arm-eabi.
There were a few problems.
One problem is that on lp64 targets (where sizeof(size_t) !=
sizeof(int)), the warning is slightly different-- and rightly so. I
have updated the test to handle both warnings on the respective targets.
The other problem is that the following snippet is incorrectly warning
on 32-bit targets:
if (n > 0 && n < 2000)
p = __builtin_alloca (n);
Looking at the gimple it seems like another case of VRP failing to give
any range information whatsoever. I have xfailed it as another case
where Andrew's upcoming work should theoretically fix this. The test is
fine on 64-bit targets.
Can y'all double check it on your respective targets as I only have a
crude cross build?
OK for the trunk whenever you're ready.
