* more pre-DWARF5 refactoring: unit headers, location cursor, range cursorNeeraj Singh2021-12-025-152/+243
| | | | | | | | | | | Read the compilation unit header byte-by-byte rather than by casting the data to a structure. Add the currentBaseAddress contextual info to the compilation unit data. Move the LOCCursor into readDwarf.cpp. Implement a RangeCursor similar to the LOCCursor. Add more debug printing.
* carry contextual information with the DIECursorNeeraj Singh2021-12-024-77/+91
| | | | | | | | | | DWARF5 has more contextual information that is associated with the compilation unit. As a preparation for using such information, carry it with the DIECursor and eliminate places where we're passing in the parent compilation unit. Also add the RDAddr helper to read a target-address according to the specification in the compilation unit.
* Refactor PE image section handling. Add debug logging.Neeraj Singh2021-12-029-171/+291
| | | | | | | | | | | Encapsulate dwarf-related PE sections into the PESection class. Remove some unused sections. Add helpers for common section operations. Move the context set via DIECursor::setContext to be static members of the class and add a debug context there. Add a standard method of enabling debug logging across the dwarf and PDB code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Git for Windows uses cv2pdb to convert the debugging information produced by GCC to `.pdb` format, for use with Visual C's tools. A recent GCC upgrade broke this because the debugging information was produced in DWARF5 format, and the Git for Windows maintainer had to scramble to implement (minimal) support for that format. Let's verify in the GitHub workflow that cv2pdb can handle GCC's output format, and let's use the very same GCC version that Git for Windows uses to verify that.

| * Allow the mspdb DLL to be found via vswhere.exeJohannes Schindelin2021-11-031-0/+67
|/ | | | | | | | | | | | | | The incredibly useful `vswhere.exe` tool can be used to abstract away all the nitty-gritty details of figuring out where Visual Studio is installed. This patch adds support for making use of that tool. Since spawning a process is pretty expensive compared to looking at the registry, we only fall back on this tool (if it exists) if the other methods to find the DLL have failed.

|/ | | | | | | | | | | | | When writing a new `.exe`/`.pdb` pair, the `.exe` might not contain any symbols. Therefore, the stale info needs to be zeroed out. This lets `dumpbin` and `objdump` accept the generated `.exe` files without problems. This fixes https://github.com/rainers/cv2pdb/issues/35 and https://github.com/git-for-windows/git/issues/2200.
