This makes a new base class, expr_builder, for parser_state. This separates the state needed to construct an expression from the state needed by the parsers. gdb/ChangeLog 2019-04-04 Tom Tromey <tom@tromey.com> * gdbarch.h, gdbarch.c: Rebuild. * gdbarch.sh (dtrace_parse_probe_argument): Change type. * stap-probe.h: (struct stap_parse_info): Replace "parser_state" with "expr_builder". * parser-defs.h (struct expr_builder): Rename from "parser_state". (parser_state): New class. * parse.c (expr_builder): Rename. (expr_builder::release): Rename. (write_exp_elt, write_exp_elt_opcode, write_exp_elt_sym) (write_exp_elt_msym, write_exp_elt_block, write_exp_elt_objfile) (write_exp_elt_longcst, write_exp_elt_floatcst) (write_exp_elt_type, write_exp_elt_intern, write_exp_string) (write_exp_string_vector, write_exp_bitstring) (write_exp_msymbol, mark_struct_expression) (write_dollar_variable) (insert_type_address_space, increase_expout_size): Replace "parser_state" with "expr_builder". * dtrace-probe.c: Replace "parser_state" with "expr_builder". * amd64-linux-tdep.c (amd64_dtrace_parse_probe_argument): Replace "parser_state" with "expr_builder".
