URL: https://github.com/llvm/llvm-project/commit/35cec805bfa91fd9b83c29c45f3a5877e484bd85 DIFF: https://github.com/llvm/llvm-project/commit/35cec805bfa91fd9b83c29c45f3a5877e484bd85.diff LOG: [lldb][test] Workaround older systems that lack gettid (#104831) Older glibc versions do not provide `gettid`. Provide our own `gettid` in these cases. Fixes a build failure caused by #104109.
