There were several problems preventing this from working. The first is that when the PDB had an absolute path to the main source file, we would construct an invalid path by prepending the compilation directory to it anyway. So we needed to check if the path is already absolute first. Second, LLDB assumes that the zero'th item in the support file list is the main compilation unit. We were respecting this requirement, but LLDB *also* requires that file to appear somewhere in the list starting from index 1 as well. So the main compilation file should appear in the support file list twice. And when parsing a line table, it expects the LineEntry records to be constructed using the 1-based index. With these two fixes we can now set breakpoints by file and line using the native PDB reader. llvm-svn: 350240
