Re: [patch/rfc] Recognize non-DW_AT_location <value optimized out> symbols
Hi Joel,
just updated the testcase to be more complete. Filed a KFAIL tracker:
http://sourceware.org/bugzilla/show_bug.cgi?id=10002
Thanks,

Recognize missing DW_AT_location as <value optimized out>.
* dwarf2read.c
(new_symbol <DW_TAG_variable> <!DW_AT_location> <!DW_AT_external>):
Call add_symbol_to_list.
gdb/testsuite/
2009-03-25 Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.dwarf2/dw2-noloc-main.c: New file.
* gdb.dwarf2/dw2-noloc.S: New symbols matrix.
(.text): Remove.
(.data): New.
(DW_AT_stmt_list, .debug_line, DW_AT_frame_base): Remove.
(DW_AT_low_pc, DW_AT_high_pc): Reference `dw2-noloc-main.c'.
(DW_TAG_subprogram func_cu1, noloc): Remove.
(main): New.
* gdb.dwarf2/dw2-noloc.exp: Use prepare_for_testing, compile also
`dw2-noloc-main.c'. Test the new DIEs from `dw2-noloc.S'.
(file_symbols): New procedure.
