New features and improvements * Added support for CCACHE_COMPILERCHECK=string:<value>. This is a faster alternative to CCACHE_COMPILERCHECK=<command> if the command’s output can be precalculated by the build system. * Add support for caching code coverage results (compiling for gcov). Bug fixes * Fixed bug which could result in false cache hits when source code contains '"' followed by " /*" or " //" (with variations). * Made hash of cached result created with and without CCACHE_CPP2 different. This makes it possible to rebuild with CCACHE_CPP2 set without having to clear the cache to get new results. * Don’t try to reset a non-existing stats file. This avoids “No such file or directory” messages in the ccache log when the cache directory doesn’t exist. * Fixed a bug where ccache deleted clang diagnostics after compiler failures. * Avoid performing an unnecessary copy of the object file on a cache miss. * Bail out on too hard compiler option -fmodules. * Bail out on too hard compiler option -fplugin=libcc1plugin (interaction with GDB). * Fixed build error when compiling ccache with recent clang versions. * Removed signal-unsafe code from signal handler. * Corrected logic for when to output cached stderr. * Wipe the whole cached result on failure retrieving a cached file. * Fixed build error when compiling ccache with recent clang versions. |
