| ; This testcase checks to make sure that we can write PDB files. It |
| ; works by first reading a known good PDB file and dumping the contents |
| ; to YAML. Then it tries to reconstruct as much of the original PDB as |
| ; possible, although depending on what flags are specified when generating |
| ; the YAML, the PDB might be missing data required for any standard tool |
| ; to recognize it. Finally, it dumps the same set of fields from the newly |
| ; constructed PDB to YAML, and verifies that the YAML is the same as the |
| ; original YAML generated from the good PDB. Note that when doing the |
| ; final comparison it must dump the original and the new pdb without any |
| ; stream metadata, since the layout of the MSF file might be different |
| ; (for example if we don't write the entire stream) |
