similar to: EH failures in MCJIT

Hi Lang, I am on Ubuntu 14.04. I am building ToT: llvm, clang, polly, lld, compiler-rt, libcxx, libcxxabi. The build compiler is: clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04 The failures show up during "make check-all". My cmake command was: cmake -G 'Unix Makefiles' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/w/c/org -DLLVM_TARGETS_TO_BUILD:STRING=all

Here's the failing tests for rc2 on SLES11.3 (glibc 2.11, libstdc++4.7). I've done some amount of triaging what some critical elements of the failures are. Unabridged log is attached. Failing Tests (94): LLVM-Unit :: ExecutionEngine/Orc/OrcJITTests/DummyRPC.TestAsyncIntInt LLVM-Unit :: ExecutionEngine/Orc/OrcJITTests/DummyRPC.TestAsyncVoidBool LLVM-Unit ::

That's useful to know that the static compilation code path works. Furthermore, as expected from that: 52: c7 05 04 00 00 00 d5 00 00 00 movl $213, 4 00000054: IMAGE_REL_I386_DIR32 _foo It looks like the offset `4` of the second field of your struct is correct in the object file, so this does seem to be a problem in the JIT-specific linking/loading.

My code was hinky, but only in the sense that I was accidentally duplicating the definition variable in the module where the function was. With only the declaration in the second module loading the bitcode reproduces the issue. Managed an lli reproduction: $ cat jit-0.ll target datalayout = "e-m:x-p:32:32-i64:64-f80:32-n8:16:32-a:0:32-S32" target triple =

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

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".

I don't think we should attempt to mangle symbols declared in assembly source files. If you're writing assembly, you will need to handle ABI portability, including the _ prefix on win32 x86. clang will run the C preprocessor for you if you use the .S file suffix (case matters).

I recently broke a sanitizer buildbot but I am unable to reproduce the failure. The buildbot that failed is http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap/builds/2959 I looked around in the logs, looking for the config/build commands that would reproduce the failure. The problem is that the bot seems to be using a script which I don't have access to
