Overview
Comment: | Change OS/2 version of sqlite3Os2FullPathname() for cross-compiler compatibility: - allocate zBuff on demand (restricted stack space on old compilers) - 2 bytes in zDrive in include '\0' - pass drive number to DosQueryCurrentDir() instead of 0 to make EMX work - zFull does not need to be preallocated (CVS 4149) |

21:18 | Remove an unnecessary temporary variable for clarity of presentation in a loop that GCC 4.2.0 is miscompiling. Ticket #2469. GCC 4.2.0 miscompiles this loop regardless of whether or not the temporary variable is used, but by removing the variable, we hope to make it easier to explain the problem to GCC maintainers. The error only appears if -ftree-vrp is used (which is turned on by -O2). (CVS 4150) (check-in: 35ae398bd3 user: drh tags: trunk) | |
