struct ThinLTOCodeGenerator::CachingOptions

Declaration

struct ThinLTOCodeGenerator::CachingOptions { /* full declaration omitted */ };

Description

These entry points control the ThinLTO cache. The cache is intended to support incremental build, and thus needs to be persistent accross build. The client enabled the cache by supplying a path to an existing directory. The code generator will use this to store objects files that may be reused during a subsequent build. To avoid filling the disk space, a few knobs are provided: - The pruning interval limit the frequency at which the garbage collector will try to scan the cache directory to prune it from expired entries. Setting to -1 disable the pruning (default). Setting to 0 will force pruning to occur. - The pruning expiration time indicates to the garbage collector how old an entry needs to be to be removed. - Finally, the garbage collector can be instructed to prune the cache till the occupied space goes below a threshold. @ {
