[PATCH] D74791: Add a --shuffle-sections=seed option to lld

[Rafael Avila de Espindola via Phabricator via llvm-commits]

respindola added a comment.

The issue reproduces with:

cmake -GNinja '-DLLVM_ENABLE_PROJECTS=clang;lld' '-DLLVM_ENABLE_RUNTIMES=libcxx;libcxxabi;libunwind' -DCMAKE_BUILD_TYPE=Release -DCLANG_BOOTSTRAP_TARGETS=check-lld -DCLANG_ENABLE_BOOTSTRAP=ON -DCLANG_DEFAULT_CXX_STDLIB=libc++ -DLIBCXX_ENABLE_SHARED=OFF -DLIBCXX_ENABLE_STATIC_ABI_LIBRARY=ON ../llvm/
ninja  stage2-check-lld

I think the problems is with std::shuffle, not the pseudo random number generation. We could copy the libc++ version to llvm's support library to get the same results in any architecture. Does that sounds like a reasonable idea?
