* | | Merge branch 'update_visitor'Josh Stone2009-02-105-603/+595
|\ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings a new update_visitor that makes it easier to traverse the parse tree and modify parts of it as necessary. I wrote this as part of my in-progress work to allow @cast() expansion, but I was able to apply it to the dwarf/etc. target variable expanders and to the optimization stages. I think the resulting code is more predictable and easier to follow... Conflicts: ChangeLog (bumped my commit dates to push dates...)
| * | | Simplify void_statement_reducerJosh Stone2009-02-102-94/+68
| | | | | | | | | | | | | | | | * elaborate.cxx (void_statement_reducer): Convert to an update_visitor.
| * | | Simplify dead_stmtexpr_removerJosh Stone2009-02-104-59/+45
| | | | | | | | | | | | | | | | | | | | | | | | * staptree.h (update_visitor::require): Add a clearok parameter for optimizing traversers to signal that they're ready for NULL back. * elaborate.cxx (dead_stmtexpr_remover): Convert to an update_visitor.
| * | | Simplify dead_assignment_removerJosh Stone2009-02-102-108/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By converting to an update_visitor, we now get full statement coverage in this optimizer for free. * elaborate.cxx (dead_assignment_remover): Convert into an update_visitor and remove its now-redundant traversal methods.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * tapsets.cxx (var_expanding_copy_visitor): This struct becomes var_expanding_visitor and inherits from update_visitor instead of deep_copy_visitor. Each of the probe-type variants of this are also no longer copiers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * staptree.h (update_visitor): A new visitor to make it easier to rewrite parts of a probe or function without making a full copy. * staptree.cxx (update_visitor::*): Each child is recursed with a require() call, and then the parent returns itself with provide(). * staptree.h (deep_copy_visitor): Inherit from update_visitor to get the recursive descent while updating nodes. * staptree.cxx (deep_copy_visitor::*): Use the implicit copy constructors to copy all fields, then defer to update_visitor for the recursion. Referents are still cleared from the copies of symbols and function calls.
| * | | Simplify require() and provide()Josh Stone2009-02-104-186/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * staptree.h (require, provide): Simplify stack operations with less pointer magic, and move to be deep_copy_visitor members. * staptree.h (deep_copy_visitor::deep_copy): Templatize * staptree.cxx, tapsets.cxx: Refactor require/provide callers

* | | | Clean up the autoconf cachingJosh Stone2009-02-077-97/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
