Entry values NEWS entries, DWARF disassembly support. * NEWS: New entry values entry. (set print entry-values, show print entry-values) (set debug entry-values, show debug entry-values): New entries. * dwarf2loc.c (disassemble_dwarf_expression): New parameters start and indent. Remove variable start. Move header printing out. Respect INDENT. Support DW_OP_GNU_entry_value. (locexpr_describe_location_1): Move the header printing here, extend the disassemble_dwarf_expression passed parameters. gdb/testsuite/ * gdb.arch/amd64-entry-value.s: New file. * gdb.mi/mi2-amd64-entry-value.s: New file.
