Verifier: Check debug info intrinsic arguments Verify that debug info intrinsic arguments are valid. (These checks will not recurse through the full debug info graph, so they don't need to be cordoned of in `DebugInfoVerifier`.) With those checks in place, changing the `DbgIntrinsicInst` accessors to downcast to `MDLocalVariable` and `MDExpression` is natural (added isa specializations in `Metadata.h` to support this). Added tests to `test/Verifier` for the new -verify checks, and fixed the debug info in all the in-tree tests. If you have out-of-tree testcases that have started to fail to -verify, hopefully the verify checks are helpful. The most likely problem is that the expression argument is `!{}` (instead of `!MDExpression()`). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232296 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-15 01:21:30 +00:00			`; RUN: not llvm-as -disable-output <%s 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			`call void @llvm.dbg.declare(metadata i32* %s, metadata !"", metadata !DIExpression()), !dbg !DILocation(scope: !1)`
