Reapply r235977 "[DebugInfo] Add debug locations to constant SD nodes" [DebugInfo] Add debug locations to constant SD nodes This adds debug location to constant nodes of Selection DAG and updates all places that create constants to pass debug locations (see PR13269). Can't guarantee that all locations are correct, but in a lot of cases choice is obvious, so most of them should be. At least all tests pass. Tests for these changes do not cover everything, instead just check it for SDNodes, ARM and AArch64 where it's easy to get incorrect locations on constants. This is not complete fix as FastISel contains workaround for wrong debug locations, which drops locations from instructions on processing constants, but there isn't currently a way to use debug locations from constants there as llvm::Constant doesn't cache it (yet). Although this is a bit different issue, not directly related to these changes. Differential Revision: http://reviews.llvm.org/D9084 llvm-svn: 235989

DI: Disallow uniquable DICompileUnits Since r241097, `DIBuilder` has only created distinct `DICompileUnit`s. The backend is liable to start relying on that (if it hasn't already), so make uniquable `DICompileUnit`s illegal and automatically upgrade old bitcode. This is a nice cleanup, since we can remove an unnecessary `DenseSet` (and the associated uniquing info) from `LLVMContextImpl`. Almost all the testcases were updated with this script: git grep -e '= !DICompileUnit' -l -- test | grep -v test/Bitcode | xargs sed -i '' -e 's,= !DICompileUnit,= distinct !DICompileUnit,' I imagine something similar should work for out-of-tree testcases. llvm-svn: 243885

IR: Give 'DI' prefix to debug info metadata Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. llvm-svn: 236120

DI: Require subprogram definitions to be distinct As a follow-up to r246098, require `DISubprogram` definitions (`isDefinition: true`) to be 'distinct'. Specifically, add an assembler check, a verifier check, and bitcode upgrading logic to combat testcase bitrot after the `DIBuilder` change. While working on the testcases, I realized that test/Linker/subprogram-linkonce-weak-odr.ll isn't relevant anymore. Its purpose was to check for a corner case in PR22792 where two subprogram definitions match exactly and share the same metadata node. The new verifier check, requiring that subprogram definitions are 'distinct', precludes that possibility. I updated almost all the IR with the following script: git grep -l -E -e '= !DISubprogram\(.* isDefinition: true' | grep -v test/Bitcode | xargs sed -i '' -e 's/= \(!DISubprogram(.*, isDefinition: true\)/= distinct \1/' Likely some variant of would work for out-of-tree testcases. llvm-svn: 246327
