[gdb/symtab] Handle DW_AT_ranges with DW_FORM_sec_off in partial DIE
While looking into a failure in gdb.go/package.exp with gcc-11, I noticed that gdb shows some complaints when loading the executable (also with gcc-10, where the test-case passes): ... $ gdb -batch -iex "set complaints 100" package.10 -ex start During symbol reading: Attribute value is not a constant (DW_FORM_sec_offset) Temporary breakpoint 1 at 0x402ae6: file gdb.go/package1.go, line 8. During symbol reading: Attribute value is not a constant (DW_FORM_sec_offset) During symbol reading: Invalid .debug_rnglists data (no base address) ... Fix this by using as_unsigned () to read DW_AT_ranges in the partial DIE reader, similar to how that is done in dwarf2_get_pc_bounds. Tested on x86_64-linux. gdb/ChangeLog: 2021-01-25 Bernd Edlinger <bernd.edlinger@hotmail.de> Simon Marchi <simon.marchi@polymtl.ca> Tom de Vries <tdevries@suse.de> * dwarf2/read.c (partial_die_info::read): Use as_unsigned () for DW_AT_ranges. gdb/testsuite/ChangeLog: 2021-01-25 Tom de Vries <tdevries@suse.de> * gdb.dwarf2/dw2-ranges-psym.exp (gdb_load_no_complaints): New proc. * lib/gdb.exp: Use gdb_load_no_complaints.
