| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * elaborate.h (unprivileged_whitelist): Removed. (unprivileged_ok): New member of match_node. (allow_unprivileged,unprivileged_allowed): New methods of match_node. * elaborate.cxx (match_node): Initialize unprivileged_ok. Remove initialization of unprivileged_whitelist.

Call unprivileged_allowed. * tapsets.cxx (dwarf_derived_probe::register_function_and_statement_variants): New parameter: unprivileged_ok. (dwarf_derived_probe::register_function_variants): Likewise. (dwarf_derived_probe::register_statement_variants): Likeiwse. (register_standard_tapsets): Call allow_unprivileged for nodes which are safe for unprivileged users.

(match_node::find_and_build): In --unprivileged mode, throw a semantic_error for probe components which are not in uinprivileged_whitelist.
* PR10070: don't warn about side-effect-free probes in -t (timing) modeFrank Ch. Eigler2009-04-141-1/+2
| | | | * elaborate.cxx (semantic_pass_opt4): Filter warning on s.timing.
* PR10026: Read marker/tracepoint args directlyJosh Stone2009-04-061-0/+3
| | | | | | | | | | We already stash the context variables for markers and tracepoints into the locals for the probe body, but then we were using separate functions to read those locals for each particular probe body. This patch instead teaches the unparser how to emit the local name directly for those context variables. The resulting code from the translator is much simpler now.

* 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.

(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.

(semantic_pass_opt5, semantic_pass_opt6): Bump opt5 to opt6, and create a new opt5 that runs through void_statement_reducer.
