You need llvm-symbolizer in PATH.

I'm getting this link failure when running ninja check on Linux. I'm configuring with shared libraries enabled, so I'm not sure why asan is looking for .a archives. $ cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_BUILD_TESTS=ON -DCLANG_INCLUDE_DOCS=ON -DBUILD_SHARED_LIBS=ON ../llvm $ ninja check-all FAILED: cd [..]bld/projects/compiler-rt/lib/asan/tests &&

Alexey, I got mail from one of the tsan buildbots, claiming a breakage in tsan tests. But I cannot see anything on the logs it has for the build. http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/17916/steps/run%2064-bit%20tsan%20unit%20tests/logs/stdio Any ideas? Thanks. Diego. ---------- Forwarded message ---------- From: <llvm.buildmaster at lab.llvm.org> Date: Wed,

Happened to me again: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/18273/steps/annotate/logs/stdio In fact, this whole bot has a 20% failure rate with the same failure mode, from looking at the history: http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/?numbuilds=50 They all end with this: [100%] Running ThreadSanitizer tests -- Testing: 258 tests, 16 threads --

Does this give correct results for special floats (0, infs)? We tried to improve (for single floats) x86 rcp in llvmpipe with newton-raphson, but unfortunately not being able to give correct results for these two cases (without even more additional code) meant it got all disabled in the end (you can still see that code in the driver) since the problems are at least as bad as those due to bad

Fixed by LLVM r262063, thanks for reporting this!

This is parallel to the pre-SM50 change which does this. Adjusts the shuffles / quadops to make the values correct relative to lane 0, and then splat the results to all lanes for the final move into the target register.

Unfortuantely we don't know if a particular load is a real 2d image (as would be a cube face or 2d array element), or a layer of a 3d image. Since we pass in the TIC reference, the instruction's type has to match what's in the TIC (experimentally). In order to properly support bindless images, this also can't be done by looking at the current bindings and generating appropriate

Retrieving the high 32 bits of a signed multiply is rather annoying. It appears that the simplest way to do this is to compute the absolute value of the arguments, and perform a u32 x u32 -> u64 operation. If the arguments' signs differ, then negate the result. Since there is no u64 support in the cvt instruction, we have the perform the 2's complement negation "by hand".

After re-cmaking and rebuilding everything from scratch, I'm seeing failures in MCJIT. It this something known or expected? I build LLVM/clang with pre-packaged clang-3.7.0, with "-stdlib=libc++". Example failure: /w/bld/org/./bin/lli -remote-mcjit -mcjit-remote-process=/w/bld/org/./bin/lli-child-target /w/src/llvm.org/test/ExecutionEngine/MCJIT/remote/eh.ll -- Exit Code:
