2.6 pre-release1 ready for testing

Tanya_Lattner · August 31, 2009, 5:50am

LLVMers,

2.6 pre-release1 is ready to be tested by the community.
http://llvm.org/prereleases/2.6/

You will notice that we have quite a few pre-compiled binaries (of both clang and llvm-gcc). We have identified several bugs that will be fixed in pre-release2, so please search the bug database before filing a new bug.

If you have time, I’d appreciate anyone who can help test the release.

To test llvm-gcc:

Compile llvm from source and untar the llvm-test in the projects directory (name it llvm-test or test-suite). Choose to use a pre-compiled llvm-gcc or re-compile it yourself.
Run make check, report any failures (FAIL or unexpected pass). Note that you need to reconfigure llvm with llvm-gcc in your path or with --with-llvmgccdir
Run “make TEST=nightly report” and send me the report.nightly.txt

To test clang:

Compile llvm and clang from source.
Run make check for llvm.
Run make -C tools/clang-2.6 test VERBOSE=1 (report any failures or unexpected passes)

When reporting your results, please provide details on what platform you compiled on, and how
you built LLVM (src == obj, or src != obj), clang, and/or llvm-gcc.

Please COMPLETE ALL TESTING BY end of the day on Sept. 5th!

Thanks, Tanya Lattner

Tanya,
Chris said he would talk to you about adding...

Author: lattner
New Revision: 80071

URL: http://llvm.org/viewvc/llvm-project?rev=80071&view=rev
Log:
"Current llvm-gcc-4.2 for trunk and the 2.6 release
is unable to build the i386 multilib for the
x86_64-apple-darwin target. The attached patch provides
this support."

Approved by Mike Stump, patch by Jack Howarth!

Modified:
llvm-gcc-4.2/trunk/gcc/config/i386/t-darwin64

to the llvm-gcc-4.2 2.6 branch. Can we get that done for
the 2.6 release so that llvm-gcc-4.2 built as x86_64-apple-darwin
can also generate i386 code via the i386 multilib as it should?

Tanya,
I can take up the clang part of testing.

Here are the results for clang testing.

I'm running the G5 PPC tests right now. Results will be slow for sure.

void · September 2, 2009, 8:19pm

Hi Tanya,

The sources weren't updated for this pre-release testing. So I had the
same problems on PPC.

Hi Tanya,

I have tried the 2.6 pre-release on the following host :

Windows XP pro SP2 with mingw/msys :

Here is the stack trace, I try to re-build :

clang::InitializePreprocessor(clang::Preprocessor&, clang::PreprocessorInitOptions const&)
clang::InitializePredefinedMacros(clang::TargetInfo const&, clang::LangOptions const&, std::vector<char, std::allocator >&)
clang::DefineTypeSize(char const*, unsigned int, char const*, bool, std::vector<char, std::allocator >&)
_sprintf

The “faulty” call to DefineTypeSize is the 5th. The one which used a “long long” type.
In the method DefineTypeSize, the call to sprintf is as follow :
sprintf(MacroBuf, “%s=%llu%s”, MacroName, MaxVal, ValSuffix);
and should be transformed to :
sprintf(MacroBuf, “%s=%I64u%s”, MacroName, MaxVal, ValSuffix);
as mingw toolchain don’t support “%llu” marker.

With this correction, clang seems to work on this platform.

I wanted to provide a patch but I’m not able to find something like “LLVM_ON_MINGW” macro definition. Sorry.
.
Thanks for your work !

Cheers,
Olivier.

Hi Tanya,

I have tried the 2.6 pre-release on the following host :

Windows XP pro SP2 with mingw/msys :

uname -a

- srcDir != objDir
- The build went fine. (configure and make)
- llvm make check : not possible under mingw (dejagnu...)
- clang make check fails :

Note that we don't really expect clang to work on MinGW yet, as far as I know.

In the method DefineTypeSize, the call to sprintf is as follow :
sprintf(MacroBuf, "%s=%llu%s", MacroName, MaxVal, ValSuffix);
and should be transformed to :
sprintf(MacroBuf, "%s=%I64u%s", MacroName, MaxVal, ValSuffix);
as mingw toolchain don't support "%llu" marker.

Fixed in SVN r80933.

I don't know the status of clang on MinGW, so its hard for me to say
whether its worth trying to take this for 2.6.

- Daniel

Olivier_Meurant · September 4, 2009, 7:58am

Thank for the fix !

I am not able to run a “make check” → dejagnu problem, but as far as I can tell clang is able to correctly generate IR files from c source. (at least on my little tests)

Olivier.

Hi Tanya, building llvm-2.6 on x86-64 linux with gcc-4.4 I see
the following warnings (also present on mainline):

llvm-2.6/runtime/libprofile/CommonProfiling.c: In function
‘write_profiling_data’:
llvm-2.6/runtime/libprofile/CommonProfiling.c:103: warning: ignoring

return value of ‘write’, declared with attribute warn_unused_result
llvm-2.6/runtime/libprofile/CommonProfiling.c:116: warning: ignoring
return value of ‘write’, declared with attribute warn_unused_result

Results (llvm-gcc built from source):

"make check" -> 1 unexpected success
(FrontendC/2009-08-11-AsmBlocksComplexJumpTarget.c)

I think Dale fixed this on mainline.

To test llvm-gcc:
1) Compile llvm from source and untar the llvm-test in the projects directory (name it llvm-test or test-suite). Choose to use a pre-compiled llvm-gcc or re-compile it yourself.
2) Run make check, report any failures (FAIL or unexpected pass). Note that you need to reconfigure llvm with llvm-gcc in your path or with --with-llvmgccdir
3) Run "make TEST=nightly report" and send me the report.nightly.txt

I've attached report.nightly.txt.

To test clang:
1) Compile llvm and clang from source.
2) Run make check for llvm.
3) Run make -C tools/clang-2.6 test VERBOSE=1 (report any failures or unexpected passes)

No failures or unexpected passes. Many warnings about aliasing problems
during the build (see PR4061).

When reporting your results, please provide details on what platform you compiled on,

x86-64 ubuntu (karmic) linux

and how

you built LLVM (src == obj, or src != obj),clang, and/or llvm-gcc.

src != obj for all,
llvm-gcc configured with: --enable-languages=c,c++,fortran

Please COMPLETE ALL TESTING BY end of the day on Sept. 5th!

Thanks for taking care of the release!

Best wishes,

Duncan.

Just a reminder that this should be wrapping up by end of day tomorrow.

There are several 2.6 bugs, so we might be pushing the release out a week to get those all fixed. I’ll update once I know more.

LLVMers,

2.6 pre-release1 is ready to be tested by the community.
http://llvm.org/prereleases/2.6/

Hi Tanya,

Here are the results for x86_64 Linux (Debian unstable):

You will notice that we have quite a few pre-compiled binaries (of
both clang and llvm-gcc). We have identified several bugs that will be
fixed in pre-release2, so please search the bug database before filing
a new bug.

If you have time, I'd appreciate anyone who can help test the release.

2) Run make check, report any failures (FAIL or unexpected pass). Note
that you need to reconfigure llvm with llvm-gcc in your path or with

3) Run "make TEST=nightly report" and send me the report.nightly.txt

Built from source, objdir != srcdir
../llvm-gcc4.2-2.6.source/configure --program-prefix=llvm-
--enable-llvm=/home/edwin/llvm2.6/obj/ --enable-languages=c,c++,fortran

XPASS:
/home/edwin/llvm2.6/llvm-2.6/test/FrontendC/2009-08-11-AsmBlocksComplexJumpTarget.c

To test clang:
1) Compile llvm and clang from source.
2) Run make check for llvm.
3) Run make -C tools/clang-2.6 test VERBOSE=1 (report any failures or
unexpected passes)

Tests OK.

Some further testing I did (not all PRs here are regressions):

ClamAV (latest git): clang OK, llvm-gcc OK

Linux 2.6.31-rc8 (patched) build fails for both:
ARCH=x86: clang: PR4689, llvm-gcc/clang: PR4628
ARCH=um: clang: PR4096, PR4689, llvm-gcc: PR4898
(note that at some point LLVM was able to compile these, not sure if it
was 2.5, or after 2.5)

Perl 5.10:
      clang: build OK, 1 test fails PR4897
      llvm-gcc: OK
valgrind 3.4.1:
       clang: build fails PR2461, PR4899;
       llvm-gcc build OK, test build fails PR4434
ACE_wrappers: llvm-gcc OK
blender 2.49b:
         llvm-gcc build OK, render matches gcc where render is
deterministic, and mean-square-error is about the same where not
         clang build OK (building only C sources), renders some blend
files differently, particularly around shaded regions: PR4900

Best regards,
