octave-antonio: libinterp/octave-value/ov-usr-fcn.cc annotate

annotate libinterp/octave-value/ov-usr-fcn.cc @ 19327:91cd85a75705 gui-release

Reduce profiling overhead using inlining and templates. * profiler.cc (profile_data_accumulator::enter::enter): Remove function. * profiler.h: Make class "enter" a templated class. Have enter constructor check whether profiling is active before calling the expensive profiler_name() function. Redefine BEGIN_PROFILER_BLOCK macro to call profile_data_accumulator::enter with a classname argument to template. * ov-builtin.cc (octave_builtin::do_multi_index_op): Use new BEGIN_PROFILER_BLOCK macro. * ov-mex-fcn.cc (octave_mex_function::do_multi_index_op): Use new BEGIN_PROFILER_BLOCK macro. * ov-usr-fcn.cc (octave_user_script::do_multi_index_op, octave_user_function::do_multi_index_op): Use new BEGIN_PROFILER_BLOCK macro. * pt-binop.cc (tree_binary_expression::rvalue1): Use new BEGIN_PROFILER_BLOCK macro. * pt-binop.h (profiler_name): New function to return profiler name for class tree_binary_expression. * pt-unop.cc (tree_prefix_expression::rvalue1, tree_postfix_expression::rvalue1): Use new BEGIN_PROFILER_BLOCK macro. * pt-binop.h (profiler_name): New function to return profiler name for class tree_prefix_expression and tree_postfix_expression.
