| 64 | /* JRS 2009-Apr-13: Mostly this PDB reader is straightforward. But |
| 65 | the biasing is incomprehensible, and I don't claim to understand it |
| 66 | at all. There are four places where biasing is required: |
| 67 | |
| 68 | - when reading symbol addresses (DEBUG_SnarfCodeView) |
| 69 | - when reading old-style line number tables (DEBUG_SnarfLinetab) |
| 70 | - when reading new-style line number tables (codeview_dump_linetab2) |
| 71 | - when reading FPO (stack-unwind) tables (pdb_dump) |
| 72 | |
| 73 | To complicate matters further, Wine supplies us, via the |
| 74 | VG_USERREQ__LOAD_PDB_DEBUGINFO client request that initiates PDB |
sewardj | 23183c0 | 2010-01-30 13:40:27 +0000 | [diff] [blame] | 75 | reading, a value 'unknown_purpose__reloc' which, if you read |
| 76 | 'virtual.c' in the Wine sources, looks a lot like a text bias |
| 77 | value. Yet the code below ignores it. |
sewardj | c8259b8 | 2009-04-22 22:42:10 +0000 | [diff] [blame] | 78 | |
| 79 | To make future experimentation with biasing easier, here are four |
| 80 | macros which give the bias to use in each of the four cases. Be |
| 81 | warned, they can and do refer to local vars in the relevant |
| 82 | functions. */ |
