| * Enable dwarf expansion of @castsJosh Stone2009-02-184-35/+406
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will iterate over the module and its CUs looking for the type definition, and then work with loc2c to dereference the pointer. * loc2c.c (c_translate_argument): Create a dummy location to start the address computation from a function parameter. * translate.cxx (base_query, dwarf_query): Move some members from base_query to dwarf_query, so the former can be more generic. Also add a constructor using a module string instead of probe parameters. (dwflpp::query_modules, dwflpp::iterate_over_modules): Use a generic base_query instead of a dwarf_query. (dwarf_cast_query): New query to scan the modules and CUs for a matching type definition, and then produce a code fragment to deref each component. (dwarf_cast_expanding_visitor): Tries to replace @casts with a function call to the result of a dwarf_cast_query. (dwflpp::declaration_resolve): Search by name instead of by die. (dwflpp::translate_components): Use the incoming vardie as the first type die, so we don't assume that attr_mem has a DW_AT_type already. (dwflpp::literal_stmt_for_pointer): Construct a C fragment that starts with a pointer argument (THIS->pointer) and dereferences each member component from there. (*_derived_probe::register_patterns): Take a session parameter instead of a match_node, so we can manipulate session-wide data. (dwarf_derived_probe::register_patterns): Add a session code filter to expand @casts with a dwarf_cast_expanding_visitor.
| * Enable session-wide code filteringJosh Stone2009-02-183-0/+18
| | | | | | | | | | | | | | | | | | | | 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.
| * Provide dwarf module names as defaults in @cast()sJosh Stone2009-02-182-0/+18
| | | | | | | | | | | | * tapsets.cxx (dwarf_var_expanding_visitor::visit_cast_op): While expanding dwarf probes, provide the current module as a default to @casts without a module name.
| * Add high-level support for @cast()ingJosh Stone2009-02-187-1/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This handles all of the parsing, traversal, and optimization. It doesn't actually resolve the cast yet though. * staptree.h (struct cast_op, visitor::visit_cast_op): New. * staptree.cxx (cast_op::print/visit, various visitor::visit_cast_op's): Incorporate cast_op into the basic tree operations. * parse.cxx (parser::parse_symbol): Parse @cast operator with an expression operand, type string, and optional module string. * translate.cxx (c_unparser::visit_cast_op): Error out if a @cast survives to translation. * elaborate.cxx (typeresolution_info::visit_cast_op): Error out if a @cast survives to type resolution. (symbol_fetcher::visit_cast_op): treat @casts as a symbol target (void_statement_reducer::visit_cast_op): unused @casts can be discarded, but the operand should still be evaluated.

* 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...)
