<pre>Follow-up from: <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - wasm64: unimplemented R_WASM_GLOBAL_INDEX_I64 using -generate-arange-section"
href="show_bug.cgi?id=52376">https://bugs.llvm.org/show_bug.cgi?id=52376</a>
As can be seen in the test code fixed in <a href="https://reviews.llvm.org/D113438">https://reviews.llvm.org/D113438</a> we
are emitting aranges for 2 separate "address spaces": data in linear memory,
and code as code section offsets. These could overlap and thus not make sense.
Since aranges does not accomodate for the concept of address spaces, the
easiest solution may be to only emit code offsets to aranges.
Aranges are being collected thru addArangeLabel in DwarfCompileUnit.cpp, and
thus some Wasm specific code filtering out data symbols may be required there?</pre>
