Hello, I am working on integrating AddressSanitizer (aka asan, http://clang.llvm.org/docs/AddressSanitizer.html) run-time library with the llvm compiler-rt. Asan needs to symbolize PCs, i.e. given a value of a PC it needs to produce the file name and the line number (if debug info is present). Currently, this is achieved by printing the PCs as /path/to/object/file+offset and filtering the output with a script which uses addr2line/atos. Ideally, symbolization should happen inside the process and should not require post processing.
I would expect that lldb already has such functionality, right? Somewhere in include/lldb/Symbol/Symtab.h? Does it work on both Linux and Mac? Do you think that it is possible/desirable to have this kind of code sharing between lldb and asan? Will that work with the current build system (where lldb and compiler-rt/lib/asan are separate subprojects)? Thanks, --kcc
