Description Luca Ceresoli 2022-06-22 12:24:45 UTC 
LLVM reproducible builds failed on opensuse154-ty-1:

https://autobuilder.yoctoproject.org/typhoon/#/builders/117/builds/1043/steps/13/logs/stdio

The reason is the llvm CMake configuration detects the pygments and pyyaml modules installed on the host, and those are present on some workers, but not all.

Here is the code detecting these modules (thanks to Richard for finding it): https://github.com/llvm/llvm-project/blob/main/llvm/cmake/config-ix.cmake#L693

The result is a difference in the computed LLVM_HAVE_OPT_VIEWER_MODULES value: http://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20220621-s2cncw_b/packages/diff-html/
