(vardecl::set_arity): Don't allow arity 0 when there's a maxsize. (vardecl::compatible_arity): Ditto. (vardecl::print): Include maxsize in output. (target_symbol::print): Ditto. * translate.cxx (struct mapvar, mapvar::mapvar): Add maxsize. (mapvar::init): Init maps with the given maxsize if specified, else keep using MAXMAPENTRIES. (mapvar::set): Make the error message give the maxsize. (mapvar::add): Ditto, and check for overflow on pmap add. (c_unparser::getmap): Pass the maxsize from the vardecl to mapvar.

* 2006-12-18 David Smith <dsmith@redhat.com>dsmith2006-12-183-0/+8

(dwarf_var_expanding_copy_visitor::visit_target_symbol): Optimization. Instead of generating one entry probe per target variable accessed in a return probe, now just generates one entry probe for all target variables accessed in a particular return probe. It does this by creating a new probe in the new 'add_probe' member variable. (dwarf_derived_probe::dwarf_derived_probe): If add_probe isn't NULL, make sure it gets derived later.
