| // PURPOSE: This module provides a low-level debug logging facility |
| // that works through all the twists and turns of program startup. Is |
| // is completely independent of everything, including all memory |
| // facilities, and emits the debug log on file descriptor 2 (stderr). |
| // This module is the first to be initialised at system startup. |
| // |
| // Because VG_(debugLog) does printf-style formatting, and because |
| // this module depends on NO OTHERS, this module contains Valgrind's |
| // vfprintf implementation too. |
