DebugInfo: Do not include variables only referenced by templates in aranges. ARanges included even extern variables referenced by pointer non-type template parameters even though that variable isn't part of this compilation unit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195895 91177308-0d34-0410-b5e6-96231b3b80d8

Disable emission of aranges by default and add a command line option to enable again that will be matched with a commit to enable in clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201378 91177308-0d34-0410-b5e6-96231b3b80d8

Revert r198208 and reapply: r198196: Use a pointer to keep track of the skeleton unit for each normal unit and construct it up front. r198199: Reapply r198196 with a fix to zero initialize the skeleton pointer. r198202: Fix aranges and split dwarf by ensuring that the symbol and relocation back to the compile unit from the aranges section is to the skeleton unit and not the one in the dwo. with a fix to use integer 0 for DW_AT_low_pc since the relocation to the text section symbol was causing issues with COFF. Accordingly remove addLocalLabelAddress and machinery since we're not currently using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198222 91177308-0d34-0410-b5e6-96231b3b80d8

Revert "Revert "DI: Fold constant arguments into a single MDString"" This reverts commit r218918, effectively reapplying r218914 after fixing an Ocaml bindings test and an Asan crash. The root cause of the latter was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a PR to investigate who requires the loose check (and why). Original commit message follows. -- This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a `\0` character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219010 91177308-0d34-0410-b5e6-96231b3b80d8
