Hi Evgeniy, I just created a new buildbot that compiles and tests compiler-rt together with LLVM/Clang using the CMake build: http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/0 There are a few ASan failures and I'd like to check with you which of them are real failures that we need to fix and which are just unsupported / noise. These tests are running on an ARMv7 machine, but I'm also building the AArch64 back-end, thus the many AArch64 errors. If possible, I'd like to run AArch64 tests, since we're not having AArch64 bots for compiler-rt any time soon. cheers, --renato
Hi, I'm not sure what's up with BuiltinLongJmpTest. I think Greg was the last to do anything about arm-linux support in asan. As for the aarch64 failures, do you want to build the aarch64 bit stuff, but not run the tests? In cmake we try to detect target platforms supported by the compiler, but we don't check that binaries actuall run. But why is there so little failures, if the hardware does not support 64-bit (or does it)?

I'd like to test everything I can, but execution AArch64 tests will obviously fail on ARM. Are there any tests that don't need execution? Like the lit tests we have for LLVM? If not, I'd still like to build AArch64 code, since that stresses LLVM on AArch64.> In cmake we try to detect target > platforms supported by the compiler, but we don't check that binaries > actuall run.I was wondering if this could be fixed in the test selection process (CMake?) to not only choose tests of the built back-ends, but the ones that could actually run. I imagine if you just run "cmake $SRC", LLVM build all back-ends by default, wouldn't that try to *run* all tests from all platforms?> But why is there so little failures, if the hardware does > not support 64-bit (or does it)?It doesn't. Not sure why so little failures... cheers, --renato
