[LLVMdev] FreeBSD tester failure
The clang-i686-freebsd-selfhost-rel buildbot is failing APIntTest.i33_Count on the first run, but the stage 2 test is passing.
It looks like it could be a miscompilation by the system gcc.
We should upgrade the system gcc on that machine, or stop testing the stage 1 llvm.
The tester is not useful as is. It is failing constantly.
Who owns this machine? Can the system be...

Yes, unfortunately on FreeBSD the first stage should be compiled using
"-O2 -fno-strict-aliasing" instead of the default optimization flags, or
this particular test...

FreeBSD user willing to try fix a unit test?
Hi all
In unittests/ADT/APIntTest.cpp I came across this test:
// XFAIL this test on FreeBSD where the system gcc-4.2.1 seems to miscompile it.
#if defined(__llvm__) || !defined(__FreeBSD__)
TEST(APIntTest, i33_Count) {
APInt i33minus2(33, static_cast<uint64_t>(-2), true);
EXPECT_EQ(0u, i33minus2.countLeadingZeros());
EXPECT_EQ(32u, i33minus2.countLeadingOnes());
EXPECT_EQ(33u, i33minus2.getActiveBits());
EXPECT_EQ(1u, i33minus2.countTrailingZeros());
EXPECT_EQ(32u, i33minus2.countPopulation()...
