uint64_t clang::HeaderSearchOptions::BuildSessionTimestamp |
The time in seconds when the build session started.
This time is used by other optimizations in header search and module loading.

unsigned clang::HeaderSearchOptions::DisableModuleHash |
Whether we should disable the use of the hash string within the module cache.
Note: Only used for testing!

unsigned clang::HeaderSearchOptions::ImplicitModuleMaps |
Implicit module maps.
This option is enabld by default when modules is enabled.

std::string clang::HeaderSearchOptions::ModuleCachePath |
The directory used for the module cache.

unsigned clang::HeaderSearchOptions::ModuleCachePruneAfter |
The time (in seconds) after which an unused module file will be considered unused and will, therefore, be pruned.
When the module cache is pruned, any module file that has not been accessed in this many seconds will be removed. The default value is large, e.g., a month, to avoid forcing infrequently-used modules to be regenerated often.

Referenced by ParseHeaderSearchArgs(), and pruneModuleCache().
unsigned clang::HeaderSearchOptions::ModuleCachePruneInterval |
The interval (in seconds) between pruning operations.
This operation is expensive, because it requires Clang to walk through the directory structure of the module cache, stat()'ing and removing files.
The default value is large, e.g., the operation runs once a week.

unsigned clang::HeaderSearchOptions::ModuleMapFileHomeIsCwd |
Set the 'home directory' of a module map file to the current working directory (or the home directory of the module map file that contained the 'extern module' directive importing this module map file if any) rather than the directory containing the module map file.
The home directory is where we look for files named in the module map file.
