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

!0 = !DIFile(filename: "scope.h", directory: "/path/to/dir")
IR: Change MDFile to directly store the filename/directory In the old (well, current) schema, there are two types of file references: untagged and tagged (the latter references the former). !0 = !{!"filename", !"/directory"} !1 = !{!"0x29", !1} ; DW_TAG_file_type [filename] [/directory] The interface to `DIBuilder` universally takes the tagged version, described by `DIFile`. However, most `file:` references actually use the untagged version directly. In the new hierarchy, I'm merging this into a single node: `MDFile`. Originally I'd planned to keep the old schema unchanged until after I moved the new hierarchy into place. However, it turns out to be trivial to make `MDFile` match both nodes at the same time. - Anyone referencing !1 does so through `DIFile`, whose implementation I need to gut anyway (as I do the rest of the `DIDescriptor`s). - Anyone referencing !0 just references an `MDNode`, and expects a node with two `MDString` operands. This commit achieves that, and updates all the testcases for the parts of the new hierarchy that used the two-node schema (I've replaced the untagged nodes with `distinct !{}` to make the diff clear (otherwise the metadata all gets renumbered); it might be worthwhile to come back and delete those nodes and renumber the world, not sure). llvm-svn: 230057

[IR] Remove the DIExpression field from DIGlobalVariable. This patch implements PR31013 by introducing a DIGlobalVariableExpression that holds a pair of DIGlobalVariable and DIExpression. Currently, DIGlobalVariables holds a DIExpression. This is not the best way to model this: (1) The DIGlobalVariable should describe the source level variable, not how to get to its location. (2) It makes it unsafe/hard to update the expressions when we call replaceExpression on the DIGLobalVariable. (3) It makes it impossible to represent a global variable that is in more than one location (e.g., a variable with multiple DW_OP_LLVM_fragment-s). We also moved away from attaching the DIExpression to DILocalVariable for the same reasons. This reapplies r289902 with additional testcase upgrades and a change to the Bitcode record for DIGlobalVariable, that makes upgrading the old format unambiguous also for variables without DIExpressions. <rdar://problem/29250149> https://llvm.org/bugs/show_bug.cgi?id=31013 Differential Revision: https://reviews.llvm.org/D26769 llvm-svn: 290153

Verifier: Check fields of MDVariable subclasses Check fields from `MDLocalVariable` and `MDGlobalVariable` and change the accessors to downcast to the right types. `getType()` still returns `Metadata*` since it could be an `MDString`-based reference. Since local variables require non-null scopes, I also updated `LLParser` to require a `scope:` field. A number of testcases had grown bitrot and started failing with this patch; I committed them separately in r233349. If I just broke your out-of-tree testcases, you're probably hitting similar problems (so have a look there). llvm-svn: 233389
