[PATCH] D125783: [llvm-debuginfo-analyzer] 08 - ELF Reader

[Carlos Alberto Enciso via Phabricator via llvm-commits]

CarlosAlbertoEnciso added a comment.

After installing `gcc-i686-linux-gnu` and using

  CC='/usr/bin/i686-linux-gnu-gcc -m32' CXX='/usr/bin/i686-linux-gnu-g++ -m32' cmake ../llvm -GNinja -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=MinSizeRel -DLLVM_TARGETS_TO_BUILD=X86 -DCLANG_ENABLE_ARCMT=OFF -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_CCACHE_BUILD=ON -DLLVM_ENABLE_PROJECTS="llvm" -DLLVM_BUILD_TESTS=OFF -DLLVM_HOST_TRIPLE=i686-pc-linux-gnu

I can reproduce the problem with

  llvm-debuginfo-analyzer --attribute=offset,level --print=scopes,sizes ../llvm/test/tools/llvm-debuginfo-analyzer/DWARF/Inputs/test-dwarf-clang.o
