* Makefile.in: Update dependencies. * dwarf2read.c: Include "addrmap.h" (struct dwarf2_cu): New fields RANGES_OFFSET and HAS_RANGES_OFFSET. (dwarf2_ranges_read): New prototype. (dwarf2_build_psymtabs_hard): Initialize and prepare PSYMTABS_ADDRMAP. Add discontiguous range to PSYMTABS_ADDRMAP by DWARF2_RANGES_READ on HAS_RANGES_OFFSET, otherwise add there the contiguous range. (dwarf2_ranges_read): New parameter RANGES_PST, update the function comment for it. Add the found ranges to RANGES_PST. New variable BASEADDR, initialize it the common way. (dwarf2_get_pc_bounds): Update the caller for the new parameter. (read_partial_die): `DW_AT_ranges' now only sets RANGES_OFFSET and HAS_RANGES_OFFSET for the later processing. * objfiles.h (struct objfile): New field PSYMTABS_ADDRMAP. * symtab.c: Include "addrmap.h" (find_pc_sect_psymtab): Support reading the field PSYMTABS_ADDRMAP. Move the psymtab locator into ... (find_pc_sect_psymtab_closer): ... a new function. gdb/testsuite/ * gdb.dwarf2/dw2-ranges.S: Merge the secondary section with `.fini'. * gdb.dwarf2/dw2-ranges.exp: Compile also `dw2-ranges2.S' and `dw2-ranges3.S' and test also their MAIN2, FUNC2 and MAIN3 symbols. * gdb.dwarf2/dw2-ranges2.S, gdb.dwarf2/dw2-ranges3.S: New files.
