| | * Enable dwarf expansion of @castsJosh Stone2009-02-181-35/+329
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| | * Provide dwarf module names as defaults in @cast()sJosh Stone2009-02-181-0/+12
| | | | | | | | | | | | | | | | | | * 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.

| * Merge branch 'update_visitor'Josh Stone2009-02-101-70/+68
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...)
| | * Expand probe variables without a deep copyJosh Stone2009-02-101-50/+46
| | | | | | | | | | | | | | | | | | | | | * 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.
| | * Simplify require() and provide()Josh Stone2009-02-101-25/+27
| | | | | | | | | | | | | | | | | | | | | * 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

| * Use 'static' as much as possibleJosh Stone2009-01-281-17/+17
| | | | | | | | | | | | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
