 |
|
When building LLVM with the -test flag, it fails 1 unit test:
| Code: |
********************
Failed Tests (1):
LLVM-Unit :: Support/./SupportTests/AlignOfTest/BasicAlignedArray
|
scrolling up in the build log gets me this (when building sys-devel/llvm-17.0.6) :
| Code: |
******************** TEST 'LLVM-Unit :: Support/./SupportTests/0/21' FAILED ********************
Script(shard):

when building 18.1.8-r1, the same test errors, but with the following instead:
| Code: |
******************** TEST 'LLVM-Unit :: Support/./SupportTests/0/21' FAILED ********************
Exception during script execution:

running /var/tmp/portage/sys-devel/llvm-18.1.8-r1/work/llvm_build-abi_x86_32.x86/unittests/Support/SupportTests gives the following:

this is a hardened LLVM-based system
any help figuring this out is appreciated. if you need more details, i'm happy to provide. |
