PR 4936: probe pont conditions part 2; reorg in prep for full rewriting
2008-01-17 Frank Ch. Eigler <fche@elastic.org>
PR 4935.
Reorganize probe condition implementation.
* elaborate.cxx (add_condition): New function.
(derived_probe): Remove condition member.
(derived_probe ctors): Assert non-null incoming probe/location ptrs.
(insert_condition_statement): Remove; turn into ...
(semantic_pass_conditions): New pass-2 subpass.
(semantic_pass_symbols, visit_symbol, visit_functioncall, find_var):
Detect some condition-related error cases.
(match_key): Change type to exp_type from tok_type. Update callers.
(alias_expansion_builder): Propagate probe conditions.
* staptree.cxx (probe): Remove condition field and related functions.
* tapsets.cxx (dwarf_derived_probe ctor): Compute replacement
wildcard-expanded probe_point preserving more of the original
location.
(mark_derived_probe ctor): Make similar to others - take location
rather than condition parameters.
* translate.cxx (emit_common_header): Tweak ordering of tmpcounter
traversal and hashkey expression generation.
* elaborate.h: Corresponding changes.

PR 4935.
* semko/forty.stp, fortyone.stp, fortytwo.stp: New tests.
* semok/twentynine.stp: Weaken test since condition expressions have
become more tightly constrained.
