* Suggest rpms to install using debuginfo-install.William Cohen2009-05-271-0/+2
| | | | | | | | | The patch makes use of the RPM libraries to determine which rpm supplied the executable and from that information suggest a command to install the appropriate debuginfo rpm. This is enabled using the "--with-rpm" option for configure. Can be explicitly disabled with "--without-rpm".

* Cache the tracepoint query resultsJosh Stone2009-03-201-0/+1
| | | | | | | To use tracepoints, we build a "tracequery" module that compiles debuginfo for all available tracepoints in the user's kernel. That's a bit of a cumbersome step to do during pass-2 though. This change adds tracequery caching so we only need to compile it once.
* PR6930: stap: supports on-file flight recorder optionsMasami Hiramatsu2009-03-201-0/+1
| | | | | | | Add on-file flight recorder options (the combination of -F and -o, and -S option) to stap command, and change manpages and NEWS. - Both of -F and -o is specified, stap passes -D option to staprun. - stap just passes -S option to staprun.

* Enable session-wide code filteringJosh Stone2009-02-181-0/+5
| | | | | | | | | | This will be used to hook to dwarf_builder to all functions and probes so it can attempt @cast expansion. * session.h (systemtap_session): Add a vector of update_visitors that will act as filters for all probes and functions. * elaborate.cxx (semantic_pass_symbols): Run probes and functions through each registered code filter.
* Clean up the autoconf cachingJosh Stone2009-02-071-0/+1
| | | | | | | | | | | | | | | | | 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().
* Save kernel autoconf options in a cache fileJosh Stone2009-02-061-0/+1
| | | | | | | | | | We're getting enough autoconf tests now that it's a significant chunk of the build time. Adding this cache shaves several seconds off for me. * hash.cxx (find_hash): Compute a separate script-independent hash for caching autoconf values, saved in session.stapconf_path. * buildrun.cxx (compile_pass): Tweak the Makefile to read/save the autoconf values in the cache directory
