* Let try_block contain any statementJosh Stone2010-03-191-2/+2
| | | | | | | We still require the block for parsing, but the optimizer likes to fold singleton blocks away, so any statement is possible. PR11341 masks such issues at compile time, but I'm a little surprised that we've gotten away with this at runtime...
* PR10831: Remember derived "aliases" in the probe chainJosh Stone2010-03-161-0/+1
| | | | | | | | | | | | | SDT and label probes are not really final probe types themselves, but rather they get translated into some other final type.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PR10026: Read marker/tracepoint args directlyJosh Stone2009-04-061-0/+1
| | | | | | | | | | 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.
