Assuming the following declarations:
type Discriminants_Record (A : Integer; B : Boolean) is record
C : Float;
end record;
Z : Discriminants_Record := (A => 1, B => False, C => 2.0);
If variable Z is not used, and the compiler optimizes it out,
GDB would crash as follow:
(gdb) print Z
/[...]/gdb/valops.c:1121: internal-error: Unexpected lazy value type.
This is because the ada-lang module forgot to set the optimized_out
flag in the value returned by ada_evaluate_subexp during the value's
"fixing" process. Later on, when trying to print the resulting value,
GDB finds that the value is still lazily allocated, and thus tries to
fetch it. But this is not allowed for not_lval values, hence the internal
error.
gdb/ChangeLog:
* ada-lang.c (coerce_unspec_val_to_type): Make sure that
the optimized_out flag is preserved.
gdb/testsuite/ChangeLog:
* gdb.ada/optim_drec: New testcase.
* gdb-index.cc (Gdb_index::pubnames_read): New parameter.
(Gdb_index::pubtypes_read): New parameter.
(Gdb_index_info_reader::read_pubnames_and_pubtypes): Add parameters
to calls.
* gdb-index.h (Gdb_index): New fields pubnames_object_ and
pubtypes_object_.
* gdbtypes.h (BOOL_PTR_CONVERSION_BADNESS): Rename to ...
(BOOL_CONVERSION_BADNESS): ... this.
* gdbtypes.c (BOOL_PTR_CONVERSION_BADNESS): Likewise.
(rank_one_type): Allow all boolean conversions
permitted by the standard.
* gdb.cp/converts.cc (A::A): Add ctor.
(A::member_): Add member.
(enum my_enum): New enumeration.
(main): Add calls to foo1_7 with various
permitted arguments.
* gdb.cp/converts.exp: Add tests for boolean
conversions permitted by the standard.
orphan sections to .data and .bss output sections, not just .text.
When giving up on finding a suitable output section, attach to any
output section other than .MMIX.reg_contents, if it exists.
* scripttempl/mmo.sc: Move output debug sections to just before
.MMIX.reg_contents. Add .gnu.attributes. Add new . = . NOP
assignments and move end-of-section provide-symbols after them
to force the end-of-section symbols to the address after orphan
placement. Add SORT_NONE to .init and .fini sections.
(Sized_target::gc_add_reference, do_gc_add_reference): New functions.
* gc.h (gc_process_relocs): Call target gc_add_reference.
* gold.cc (queue_middle_tasks): Use gc_mark_symbol on start sym.
* symtab.cc (Symbol_table::gc_mark_undef_symbols): Use gc_mark_symbol.
(Symbol_table::gc_mark_symbol): Call target gc_mark_symbol. Remove
unnecessary cast.
* powerpc.cc (Powerpc_relobj::get_opd_ent): Rearrange parameters
to cater for when we don't need code offset. Update use.
(Powerpc_relobj::access_from_map_, opd_valid_): New vars.
(Powerpc_relobj::access_from_map, add_reference, opd_valid,
set_opd_valid): New functions.
(Target_powerpc::do_gc_add_reference): New function.
(Target_powerpc::gc_process_relocs): Call gc()->add_reference on
stashed refs.
(Target_powerpc::do_gc_mark_symbol): New function.
Replace -nw option with $INTERNAL_GDBFLAGS in "xgdb" tests to
avoid spurious results due to ~/.gdbinit.
* gdb.gdb/complaint.exp (setup_test): Replace -nw option with
$INTERNAL_GDBFLAGS in run command.
* gdb.gdb/observer.exp (setup_test): Ditto.
* gdb.gdb/selftest.exp (test_with_self): Ditto.
* gdb.gdb/xfullpath.exp (setup_test): Ditto.
* config/tc-s390.c (set_highgprs_p): New variable.
(s390_machinemode): New function.
(md_pseudo_table): Add new pseudo command machinemode.
(md_parse_option): Set set_highgprs_p to TRUE if -mzarch was
specified on command line.
(s390_elf_final_processing): Set the highgprs flag in the ELF
header depending on set_highgprs_p.
* doc/c-s390.texi: Document new pseudo machinemode.
