LGTM. I think it is totally reasonable to just disable LSan directly in tablegen at least for now. I would leave some comments on the disabling to clarify: 1) What it does, the reader may not have heard about LSan. 2) Some of the high-level information from this thread as pointers for anyone who wants to go and fix this some day. -Chandler On Wed, Dec 25, 2013 at 2:26 PM, Kostya Serebryany

I get leaks from a system library: ==16272==ERROR: LeakSanitizer: detected memory leaks Direct leak of 148 byte(s) in 2 object(s) allocated from: #0 0x4a3172 in __interceptor_malloc .../build/../projects/compiler-rt/lib/asan/asan_malloc_linux.cc:40:3 #1 0x7f575d8df1fe in wcsdup (/lib64/libedit.so.0+0x1c1fe) I don't think I can fix this... ;] -Chandler -------------- next part

Are multi-output patterns in TableGen supposed to work, or is that a known limitation in the current implementation? If I have TableGen code like the following... 1242 def SDTTestNode : SDTypeProfile<2, 1, [SDTCisSameAs<0, 1>]>; 1243 def TestNode : SDNode<"NVPTXISD::TestNode", SDTTestNode>; 1244 1245 def MyTestNode : NVPTXInst<(outs Int32Regs:$dst0,

Thanks for the info. Is this on someone's list of things to do?

Dear testers, 3.7.0-rc1 was just tagged; please start your testing engines :-) Upload binaries to the sftp and report your results to this thread. I'm sorry for the delay between branching and tagging. The changes to the release script took a little longer than I hoped. Thanks for helping with the release, and do let me know of any issues, questions, etc. The tracking bug for release

Hi, I implemented a pattern matching of the dot product for arm64 and it seemed to work well for the basic case, i.e., class mulB<SDPatternOperator ldop> : PatFrag<(ops node:$Rn, node:$Rm, node:$offset), (mul (ldop (add node:$Rn, node:$offset)), (ldop (add node:$Rm, node:$offset)))>; class mulBz<SDPatternOperator ldop> : PatFrag<(ops node:$Rn,

Dear testers, 3.7.0-rc2 was just tagged. Please test, build binaries, upload to the sftp, and report results to this thread. A lot of fixes have been applied since rc1, both to the build script and the code in general, so hopefully it will be less bumpy this time. >From this point, I will no longer accept merge requests to finish existing features; it's now bug-fixes only. Thanks again

It has been something we've talked about for years, but I'm not aware of anyone working on it right now.

Hi, I'm currently trying to find and fix memory leaks (compiling with ``-fsanitize=address``) in the KLEE tool [1] an having found some leaks and I'm having trouble suppressing them. I'm trying to suppress them using the ``-fsanitize-blacklist=blacklist.txt`` option as documented at [2]. I'm using Clang 3.7 ( Arch Linux package 3.7.0-6). The sort of reported leaks I see are ```

Hi, Currently the first stage ("run sanitizer tests in gcc build") of the sanitizer-ppc64-linux1 buildbot is only failing because of: + cd clang_build + make -j16 check-lsan make: *** No rule to make target `check-lsan'. Stop. + echo @@@STEP_FAILURE@@@ @@@STEP_FAILURE@@@ + cd clang_build + make -j16 check-msan make: *** No rule to make target `check-msan'. Stop. + echo

How about tweaking the compiler-rt cmakefiles so that if lsan is not supported, the target check-lsan still exists but does nothing? I've attached a patch that does this. (I don't know much about cmake so there might be a better way of doing it.) Alternatively, can I change the zorg build script so that "run sanitizer tests in gcc build" doesn't try to run check-lsan etc

Hi all, TL;DR 1) We should change the way we parse common runtime flags in sanitizers. 2) We should make ASan aware of the tools it can be combined with (LSan and UBSan). 3) We may have to restrict the tools UBSan can be combined with (currently to ASan) (see [1]) Currently we have two kinds of sanitizer runtime flags: tool-specific flags and "common flags", defined in sanitizer_common

Dear testers, Release Candidate 3 has just been tagged [1]. Please build, test, and upload to the sftp. If there are no regressions from previous release candidates, this will be the last release candidate before the final release. Release notes can still go into the branch. Thanks again for all your work! Hans [1] http://lists.llvm.org/pipermail/llvm-branch-commits/2016-February/009866.html
