* PR10543: do module cache cleaning before copying new file into the cacheFrank Ch. Eigler2009-08-211-2/+4
| | | | | | ... otherwise the new stuff can get cleaned before use. * cache.cxx (add_to_cache): Do clean_cache() first, not last.

| | | | | | | | | | | | Don't generate an error message for unsigned modules. Make sure module signature exists before attempting to copy to the cache. Allow timer p[robes for unprivileged users.

* Clean up the autoconf cachingJosh Stone2009-02-071-45/+117
| | | | | | | | | | | | | | | | | This makes the stapconf caching process quite a bit more transparent. The options are now cached in a header file as #defines, and this header file is a normal build dependency instead of calling so many make $(shell ...) commands. * buildrun.cxx (compile_pass): Pull in autoconf options in a header of #defines rather than -DXXX, and make that header a build dependency. * buildrun.cxx (output_autoconf): New function to consolidate the computation of each autoconf test. * cache.cxx (add_to_cache, get_from_cache, clean_cache): Start treating the stapconf header as a first-class cached item. * cache.h: Move definitions of things only needed in cache.cxx * hash.cxx (find_stapconf_hash): Generate stapconf_name as a .h now. * main.cxx (main): Default the stapconf_name based on getpid().
