<div dir="ltr">Hey folks,<br><br>So I've been doing some more testing/implementation work on various address pool reduction strategies previously discussed back in January ( <a href="http://lists.llvm.org/pipermail/llvm-dev/2020-January/thread.html#138029">http://lists.llvm.org/pipermail/llvm-dev/2020-January/thread.html#138029</a> ).<br><br>I've committed a -mllvm flag to allow experimenting with the first of these strategies: Always using ranges in DWARFv5 (the flag has no effect pre-v5). Since ranges can use address pool entries, this allows significant address reuse (clang opt split-dwarf 13% reduction in object file size, specifically a reduction in aggregate .rela.debug_addr size from 78MB to 16MB - the lowest this could go is approximately 8MB (this is the size of .rela.debug_line)).<br><br>It causes one lldb test to fail lldb/test/SymbolFile/DWARF/Output/debug-types-expressions.test which reveals that lldb has some trouble with ranges on DW_TAG_subprograms.<br><br>Anyone happen to have ideas about what the problem might be? Anyone interested in fixing this? (Jordan, maybe?) <br><br>Sri: Sounded like you folks had done some testing of Propeller with lldb - and I'd expect it to trip over this same problem, since it'll cause ranges to be used for DW_TAG_subprograms to an even greater degree. Have you come across anything like this? <br><br>Here's a small example:<br><br>(the test has an inline function to force the output file to have more than one section (otherwise it'll all be in the text section, the CU's low_pc will be relocatable and all the other addresses will be relative to that - so there won't be any benefit to using ranges) and 'main' is the second function, so it starts at an offset relative to the address in the address pool (which will be f2's starting address) and benefit from using ranges to share that address)<br><br>
