Test-suite log files
I got this test failure on freebsd-9.2 platform with a clang as system
compiler:
$ clang --version
FreeBSD clang version 3.3 (tags/RELEASE_33/final 183502) 20130610
Target: x86_64-unknown-freebsd9.2
Thread model: posix
1. Compile latest clang version (for me it was r193247).
2. Check it with test-suite. I did it with next command:
gmake VERBOSE=1 TEST=nightly report 1>test-suite-freebsd-9.2.log
2>test-suite-freebsd-9.2.err
`mandel` test fails with next message (quoted from .log file):
******************** TEST (jit) 'mandel' FAILED! ********************
Execution Context Diff:
/usr/home/buildslave/manualbuild/test-suite-clang-compiled-build.obj/tools/fpcmp:
Compared: -2.147484e+09 and -9.999000e+03
abs. diff = 2.147474e+09 rel.diff = 2.147688e+05
Out of tolerance: rel/abs: 1.000000e-03/0.000000e+00
******************** TEST (jit) 'mandel' ****************************
I consider it as clang bug, that only fired during bootstrapping with r183502
version. As base for this opinion I use fact, that it this test passed on
freebsd-8 machines with gcc system compiler.
Any questions are welcome.</pre>
