Verifier: Move checks over from DIDescriptor::Verify() Move over some more checks from `DIDescriptor::Verify()`, and change `LLParser` to require non-null `file:` fields in compile units. I've ignored the comment in test/Assembler/metadata-null-operands.ll since I disagree with it. At the time that test was written (r229960), the debug info verifier wasn't on by default, so my comment there is in the context of not expecting the verifier to be useful. It is now, and besides that, since r233394 we can check when parsing textual IR whether an operand is null that shouldn't be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233654 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-31 00:47:15 +00:00			`; RUN: not llvm-as < %s -disable-output 2>&1 \| FileCheck %s`

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236120 91177308-0d34-0410-b5e6-96231b3b80d8 2015-04-29 16:38:44 +00:00			`!0 = !DICompileUnit(file: null)`
