Tests segfault on armv7l architecture
sergiopasra opened this issue · comments
Hi, I have packaged llvmpy for Fedora Linux. Fedora now has armv7l as one of its primary architectures, that means that all packages are build on it by default.
I have noticed that the tests in llvm.test() in version 0.12.0 fail with segmentation fault in this particular architecture.
the problem seems to be in test_cpu_support2
$ arch
armv7l
$ nosetests -v /opt/lib/python2.7/site-packages
(...)
test_bitcode (llvm.test_llvmpy.TestAsm) ... ok
test_atomic_cmpxchg (llvm.test_llvmpy.TestAtomic) ... ok

test_atomic_rmw (llvm.test_llvmpy.TestAtomic) ... ok

Stack dump:
0. Running pass 'ARM Machine Code Emitter' on function '@mysin'
Segmentation fault
I have set up a virtual machine to make this test, I do not own armv7l hardware my self. I have followed to instructions here https://fedoraproject.org/wiki/Architectures/ARM/F19/Installation#For_Versatile_Express_Emulation_with_QEMU to setup the VM.
Some of the tests are architecture specific. We really haven't been testing on non x86 arch yet. I will be reviewing the tests.

I'm seeing the same issue on aarch64 (arm64) so it would be useful to have architecture specific tests so that both the non x86 tests aren't run but also to have tests for non x86 too
