[lldb-dev] PDB symbol reader status?
Hi, What is the current status of LLDB's PDB file parser on Windows? It was announced back in 2015 that PDB support is coming soon, so I was wondering where it's at currently. ___ lldb-dev mailing list lldb-dev@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
Re: [lldb-dev] PDB symbol reader status?
Basic PDB support is in LLDB if you're running on Windows. LLDB has a SymbolFilePDB plugin that relies on a PDB abstraction in LLVM. There is currently just one implementation of that abstraction, and it relies on DIA, which is a Microsoft-provided DLL on Windows for looking up information in a PDB. I'm currently working on a native PDB reader that implements the same interface without reliance on DIA, so that should eventually provide the same functionality even if you're not running on Windows. Browsing through the PDB plugin in LLDB, I see a lot of "//TODO: Implement this" methods, so you won't (yet) have rich type information. But you can set breakpoints by name, get a stack backtrace, print variable values, etc. On Wed, Jul 26, 2017 at 11:19 AM, Vadim Chugunov via lldb-dev < lldb-dev@lists.llvm.org> wrote: > Hi, > What is the current status of LLDB's PDB file parser on Windows?

Re: [lldb-dev] PDB symbol reader status?
I'm trying to use LLDB built from svn trunk: for MSVC emitted binaries it cannot set any breakpoints, and for clang-cl outputs it crashes when setting a breakpoiint by file/line. Are these scenarios supposed to work? WinDbg works fine in both cases, so the debug info is probably ok. (I'm using VS 2017 Build Tools, if that matters).

For clang-cl you need to use -fuse-ld=lld. For msvc only a small amount of pdb support was added to lldb, namely the ability to resolve file and line info.

Why -fuse-ld=lld? What does lld do differently than MS linker? On Wed, Jul 26, 2017 at 1:10 PM, Zachary Turner wrote: > For clang-cl you need to use -fuse-ld=lld.
