[Dwarf-Discuss] Confusion about .debug_str_offsets[.dwo]
Sun Aug 30 23:59:14 GMT 2020
If a DW_UT_split_compile in 'test.dwp'
? has a compilation unit? DW_TAG_compile unit
? with strings and referencing via DW_FORM_strx1
? And there is a test.dwp with a .debug_str_offsets.dwo
? the compile unit will not have a
? DW_AT_str_offsets_base (by sec 3.1.3)
? but the DW_AT_str_offsets_base from the 'test' skeleton
? will have the DW_AT_str_offsets_base for
If skeleton in executable 'test' has a .debug_str_offsets
? and a DW_TAG_skeleton_unit
? it may have strings referenced with DW_FORM_strx1 and
? DW_AT_str_offsets_base then..? How is one to refer
? to the strings given the content of .debug_str_offsets
? will surely not match .debug_str_offsets.dwo
Section 3.1.2 , on skeleton units:
?A skeleton compilation unit may have additional attributes,
?which are the same as for conventional compilation unit
?entries except as noted, from among the following:
Does that mean ONLY the following units?
DW_AT_dwo_name is specifically allowed in the skeleton.
It might be DW_FORM_strx1? Right?
Two .debug_str_offsets? (one .dwo)
tables, one base.? How could that work?
I'll think about this further, but if anyone
would care to clarify this it would be great.
