This is the original proposal. [ Return to the latest version ]
BACKGROUND
References are to DWARF5 unless otherwise indicated.
If a split-full CU uses DW_FORM_rnglistx,
is a DW_AT_rnglists_base required?
Apparently not, though
in cases I have seen in object files are instances
of a single rnglist in .debug_rnglists.dwo.
The operative assumption is consumers will
simply assume zero as the (missing)
DW_AT_rnglists_base.
Seen in llvm and gcc.
The intent of this proposal is to get clarity.
An alternative version could state:
If a Split Full Compilation Unit refers to
.debug_rnglists.dwowithDW_FORM_rnglistxthe CU DIE must have aDW_AT_rnglists_baseattribute.
PROPOSAL
At the end Sec F.1 Overview just before Table F.1:
If a Split Full Compilation Unit refers to
.debug_rnglists.dwowithDW_FORM_rnglistxand the correctDW_AT_rnglists_basewould be zero, theDW_AT_rnglists_basemay be omitted.
