annotate libinterp/parse-tree/pt-idx.cc @ 33309:d422992b5483

refactor position tracking in the parser This change replaces direct source line and column tracking in the tree_* classes with the beginning and ending positions in tokens created by the lexer. All line and column arguments for tree_* constructors have been removed. More tree_* classes have been modified to store tokens that are part of the syntax but not necessary for evaluation. Affected files: cdef-class.cc, ov-fcn.cc, ov-fcn.h, ov-usr-fcn.cc, ov-usr-fcn.h, bp-table.cc, oct-parse.yy, parse.h, pt-arg-list.cc, pt-arg-list.h, pt-args-block.h, pt-array-list.h, pt-assign.cc, pt-assign.h, pt-binop.cc, pt-binop.h, pt-cbinop.cc, pt-cbinop.h, pt-cell.cc, pt-cell.h, pt-classdef.cc, pt-classdef.h, pt-cmd.h, pt-colon.cc, pt-colon.h, pt-const.cc, pt-const.h, pt-decl.cc, pt-decl.h, pt-eval.cc, pt-except.h, pt-exp.h, pt-fcn-handle.cc, pt-fcn-handle.h, pt-id.h, pt-idx.cc, pt-idx.h, pt-jump.h, pt-loop.h, pt-mat.cc, pt-mat.h, pt-misc.h, pt-select.h, pt-spmd.h, pt-stmt.cc, pt-stmt.h, pt-unop.cc, pt-unop.h, pt.cc, and pt.h.
