| * Add update_visitor::replaceJosh Stone2009-08-038-72/+77
| | | | | | | | | | | | | | | | | | | | | | | | I noticed that most uses of update_visitor::require() were simply writing the value back to the same place, i.e. foo = require(foo). The new replace() method just encapsulates that paradigm, so we don't have the duplication between the LHS and RHS. * staptree.h (update_visitor::replace): New. * elaborate.cxx, staptree.cxx, tapset-mark.cxx, tapset-perfmon.cxx, tapset-procfs.cxx, tapset-utrace.cxx, tapsets.cxx: Update all require calls that are simply updating the value in-place.
| * Strengthen the template types in update_visitorJosh Stone2009-08-032-7/+7
| | | | | | | | | | * staptree.h (update_visitor::require, provide): Make the parameters and return values a T*, to make it explicit that we want pointer types.

| | * PR2049: support arbitrary $target-array indexingJosh Stone2009-08-038-25/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than just numeric literals, we can now support arbitrary expressions for the index value. Note that loc2c won't allow this for noncontiguous arrays, as the access methods need to be statically computed, but for contiguous arrays and pointers-as-arrays it works just fine. * staptree.h (target_symbol::component): Add expression_array_index. * staptree.cxx (target_symbol::visit_components): New helper. (target_symbol::assert_no_components): Recognize new array type. (target_symbol::component::print): Print subexpressions. (traversing_visitor::visit_target_symbol, visit_cast_op): Visit the indexing components too. (varuse_collecting_visitor::visit_target_symbol): Ditto. (update_visitor::visit_target_symbol, visit_cast_op): Ditto. * elaborate.cxx (void_statement_reducer::visit_target_symbol): New. (void_statement_reducer::visit_cast_op): Save indexes too. * parse.cxx (parser::parse_target_symbol_components): Parse expressions. * tapsets.cxx (dwarf_var_expanding_visitor::visit_target_symbol): Pass expression-indexes as parameters (indexN) to the dwarf function. (dwarf_cast_expanding_visitor::visit_cast_op): Ditto. (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Ditto. (sdt_var_expanding_visitor::visit_target_symbol): Visit the new @cast. * dwflpp.cxx (dwflpp::translate_components): Use THIS->indexN. * translate.cxx (c_unparser::visit_target_symbol): Correct error msg. * testsuite/systemtap.base/pointer_array.stp: Use a simple index.
| | * Unify no-component assertions on target variablesJosh Stone2009-07-317-131/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several tapsets that can't deal with component dereferences on their target variables, and they all check-and-throw in the same way. This refactors the checks into a target_symbol member. * staptree.cxx (target_symbol::assert_no_components): New. * tapsets.cxx (tracepoint_var_expanding_visitor::visit_target_symbol_arg, tracepoint_var_expanding_visitor::visit_target_symbol_context): Use the new assertion function to check for no components. * tapset-mark.cxx (mark_var_expanding_visitor::visit_target_symbol_arg, mark_var_expanding_visitor::visit_target_symbol_context): Ditto. * tapset-perfmon.cxx (perfmon_var_expanding_visitor::visit_target_symbol): Ditto. * tapset-procfs.cxx (procfs_var_expanding_visitor::visit_target_symbol): Ditto. * tapset-utrace.cxx (utrace_var_expanding_visitor::visit_target_symbol_arg, utrace_var_expanding_visitor::visit_target_symbol_context): Ditto.
| | * Make a real type for target_symbol->componentsJosh Stone2009-07-3110-72/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the dereferences on target_symbol and cast_op are tracked with a struct instead of just a generic pair. The first immediate benefit is that we can track the token for more exact error reporting. * staptree.h (target_symbol): Add a new component type. * staptree.cxx (target_symbol::component::print): New. (operator<<(ostream&, target_symbol::component&): New. (target_symbol::print): Adapt component printing. (cast_op::print): Ditto. * parse.cxx (parser::parse_target_symbol_components): Adapt to the new component construction. * dwflpp.cxx (dwflpp::find_struct_member): take the component as a parameter for a better token in error messages (dwflpp::translate_components): Adapt to the new component type. * tapsets.cxx (dwarf_var_expanding_visitor::visit_target_symbol): Don't overwrite the token in target_symbol saved errors. (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Ditto.
| | * Refactor parser for target_symbol->componentsJosh Stone2009-07-312-42/+33
| | | | | | | | | | | | | | | | | | | | | | | | The components were being parsed for both target_symbols and cast_ops, so this change refactors that code into a single function. * parse.cxx (parser::parse_target_symbol_components): New. (parser::parse_symbol): Use the new function.
| | * Drop a couple of unnecessary std:: qualifiersJosh Stone2009-07-311-2/+2

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setup the pt_regs REG_IP to the actual breakpoint address before entering a probe handler for [ku]probe[ret] (and restore it after returning). This helps getting symbol resolution and backtraces more correct and makes it more conform with other probe handlers like the iutrace and profile timers that also provide pt_regs (which untill now exhibited off-by-one errors while unwinding). * tapsets.cxx (dwarf_derived_probe_group::emit_module_decls): Setup REG_IP correctly before calling enter_kprobe_probe and enter_kretprobe_probe, and restore afterwards.
