ELF: Add ThinLTO caching support. This patch adds an option named --thinlto-cache-dir, which specifies the path to a directory in which to cache native object files for ThinLTO incremental builds. Differential Revision: https://reviews.llvm.org/D30509 llvm-svn: 296702

ELF: Add cache pruning support. This patch causes us to use pruneCache() to prune the ThinLTO cache after completing LTO. A new flag --thinlto-cache-policy allows users to configure the policy. Differential Revision: https://reviews.llvm.org/D31021 llvm-svn: 298036

Support, LTO: When pruning a directory, ignore files matching a prefix. This is a safeguard against data loss if the user specifies a directory that is not a cache directory. Teach the existing cache pruning clients to create files with appropriate names. Differential Revision: https://reviews.llvm.org/D31109 llvm-svn: 298271

[ELF] Fix broken LTO cache test NFC Commit r318397 fixed the cache pruning interval which broke this test as it was assuming that the cache pruning was always being performed. Explicitly set prune interval to 0s to ensure this. llvm-svn: 318426

Add a ThinLTO cache policy for controlling the maximum cache size in bytes. This is useful when an upper limit on the cache size needs to be controlled independently of the amount of the amount of free space. One use case is a machine with a large number of cache directories (e.g. a buildbot slave hosting a large number of independent build jobs). By imposing an upper size limit on each cache directory, users can more easily estimate the server's capacity. Differential Revision: https://reviews.llvm.org/D34547 llvm-svn: 306126

CachePruning: Allow limiting the number of files in the cache directory. The default limit is 1000000 but it can be configured with a cache policy. The motivation is that some filesystems (notably ext4) have a limit on the number of files that can be contained in a directory (separate from the inode limit).
