LLVM 3.0rc3 Testing Beginning

Project Infrastructure LLVM Dev List Archives
1

Good day, LLVMers!

We are starting on our third (and hopefully last) round of testing for LLVM 3.0. Please visit:

  http://llvm.org/pre-releases/3.0/rc3/

for the sources. There are also binaries for Darwin up there, with more to come during the week. Please build this release candidate, test it out on your projects, and let us know if you find any regressions from the 2.9 release.

Please keep in mind that we are not taking any more fixes except for those issues which are critical for the release.

Share and enjoy!

Especially if you're running Linux, please give Clang in RC3 a spin, even if you previously tested RC2. We've updated the header-search logic to try to make Clang more robust against different system include directory layouts, and need help with more widespread testing.

Which files are needed to build clang? Is it clang-3.0rc2 and llvm-3.0rc3 or do I need the whole test suite?

I've done a "make -j2 all check-all", llvm + clang, Release build, on
Ubuntu Linux 11.04 x86_64. I got one test failure:

Failing Tests (1):
    Clang-Unit :: AST/Release/ASTTests/APValue.Diagnostics

I've pasted the output of the test below.

Jay.

Both clang-3.0rc3 and llvm-3.0rc3. The test-suite sources are only needed if you're going to run the full test suite.

You probably don't need the whole test-suite. There's a symlink to it, but I think it'll be ignored.

Jay,

Did you see these failures for rc2?

Chandler,

Could these be related to your changes?

-bw

8

Extremely unlikely. I’ll investigate though.

I never tried rc2. I could give it a go tomorrow, if it's still
available for download.

Jay.

It's there. Thanks! :slight_smile:

On Linux Debian testing, gcc-4.6.1:

Built fine, with warnings listed below

make check-all passed

I couldn't figure out how to run the test-suite. Are there up-to-date
instructions somewhere? llvm-gcc doesn't exist anymore...

I get the following warnings building llvm+clang (default configure,

Easiest is to check out the test-suite branch into projects and then after you configure and build from the top level, go into build/projects/test-suite and do a ‘make TEST=simple report’.

Yes.

Easiest is to check out the test-suite branch into projects and then after you configure and build from the top level, go into build/projects/

This fails miserably for me:

Doesn't appear to be finding your built compiler. Can you send me a private email with the output of config.log when you reconfigure and your source checkout lines?

Thanks!

I’m not sure if this makes a difference but I ran this

make -j 2 -k LLVMCC_OPTION=clang ENABLE_BUILT_CLANG=1 ENABLE_PARALLEL_REPORT=1 TEST=simple report > …/…/report.txt 2>&1

inside

rc3/Phase3/Release/llvmCore-3.0-rc2.obj/projects/llvm-test

That test passes for me on Fedora 15 x86_64 (gcc-4.6.1-9.fc15.x86_64).

The one change I had to do is remove the compiler flags pointing Clang
to the system C/C++ headers, otherwise the related test fails:

FAIL: Clang :: Driver/linux-ld.c (1949 of 3941)

Hello:

Newbie here. I just tested the LLVM 2.9 today and found the in-line assembly of clang/llvm do not handle 128-bit integer very well (as gcc-does).
Both Apple and Linux version seem affected. I will try 3.0rc3 tomorrow to see if fixed.

Thanks.
