Hello, We noticed that the original bugzilla, which intended to add new LLVM toolchain support[1], also wanted to bring ELF format support with DWARF debugging information. For some reason this did not make its way into EDK II, and we are currently wondering, how can one debug binaries built with LLVM 9.0.
For macOS and XCODE5 toolchain we use GDB scripts based on Andrei Warkentin’s work, which allow us to integrate with QEMU and VMware[2]. It is likely that they should work with little to no work on Linux with CLANG38/GCC5 with GDB once again. However, CLANGPDB apparently is using PDB debugging information, which I believe is not handled with GDB. Could you please provide the details on the matter and let us know about the recommended route? — Is dropping CLANGELF just a temporary measure and it should be resubmitted again? — Should LLDB, which seems to be aware of PDB, be used instead of GDB, when building with CLANGPDB? If so, did anybody try that? Thanks!
