--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
Debug info looks like:
...
Compilation Unit @ offset 0xf4:
Length: 0x35 (32-bit)
Version: 5
Unit Type: DW_UT_compile (1)
Abbrev Offset: 0xa3
Pointer Size: 8
<0><100>: Abbrev Number: 3 (DW_TAG_unspecified_type)
<0><101>: Abbrev Number: 1 (DW_TAG_compile_unit)
<102> DW_AT_stmt_list : 0x123
<106> DW_AT_low_pc : 0x4004ac
<10e> DW_AT_high_pc : 11
<10f> DW_AT_name : test2.s
<113> DW_AT_comp_dir : /home/vries/gdb_versions/devel
<117> DW_AT_producer : GNU AS 2.39.50
<11b> DW_AT_language : 32769 (MIPS assembler)
<1><11d>: Abbrev Number: 2 (DW_TAG_subprogram)
<11e> DW_AT_name : (indirect string, offset: 0x241): foo
<122> DW_AT_external : 1
<122> DW_AT_type : <0x100>
<123> DW_AT_low_pc : 0x4004ac
<12b> DW_AT_high_pc : 11
...
OK, that looks highly unregular, the DW_TAG_unspecified_type die as a top-level
DIE.
