* BZ 9719: Improve type mismatch messagesRajan Arora2009-02-181-6/+53
|
* Bump copyright years to 2009Josh Stone2009-02-181-1/+1
|
* Enable session-wide code filteringJosh Stone2009-02-181-0/+6
| | | | | | | | | | 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.
* Add high-level support for @cast()ingJosh Stone2009-02-181-0/+31
| | | | | | | | | | | | | | | | | | 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.
* Simplify void_statement_reducerJosh Stone2009-02-101-94/+67
| | | | * elaborate.cxx (void_statement_reducer): Convert to an update_visitor.
* Simplify dead_stmtexpr_removerJosh Stone2009-02-101-54/+37
| | | | | | * 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 Stone2009-02-101-108/+16
| | | | | | | | 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.

* Get rid of the dynamic_cast<>s in void_statement_reducer.Josh Stone2008-06-191-57/+49
| | | | | | | | Instead, visit_expr_statement can explicitly load a pointer to use for back-references. I also decided to be less-clever about reusing expr_statements. It's a little leakier as a result, but I like having less magic in the air.

* New optimization to break up statements in void contexts.Josh Stone2008-06-181-19/+419
| | | | | | | | | | | | | | | | PR 6644 * elaborate.cxx (dead_stmtexpr_remover::visit_block): Flatten nested block statements into a single block. (dead_stmtexpr_remover::visit_if_statement): Remove the possibility of if_statements with a null thenblock. When an if lacks both then and else, either remove it completely or reduce it to a simple statment evaluating the condition. With an else and no then, invert the condition and else becomes then. (void_statement_reducer): New optimization visitor that breaks statements in void context into smaller pieces, to expose more optimization opportunities. (semantic_pass_opt5, semantic_pass_opt6): Bump opt5 to opt6, and create a new opt5 that runs through void_statement_reducer.
