Reapply "Linker: Drop superseded subprograms" This reverts commit r224416, reapplying r224389. The buildbots hadn't recovered after my revert, waiting until David reverted a couple of his commits. It looks like it was just bad timing (where we were both modifying code related to the same assertion). Trying again... Here's the original text: When a function gets replaced by `ModuleLinker`, drop superseded subprograms. This ensures that the "first" subprogram pointing at a function is the same one that `!dbg` references point at. This is a stop-gap fix for PR21910. Notably, this fixes Release+Asserts bootstraps that are currently asserting out in `LexicalScopes::initialize()` due to the explicit instantiations in `lib/IR/Dominators.cpp` eventually getting replaced by -argpromotion. llvm-svn: 224487

Reapply "Linker: Drop function pointers for overridden subprograms" This reverts commit r233254, effectively reapplying r233164 (and its successors), with an additional testcase for when subprograms match exactly. This fixes PR22792 (again). I'm using the same approach, but I've moved up the call to `stripReplacedSubprograms()`. The function pointers need to be dropped before mapping any metadata from the source module, or else this can drop the function from new subprograms that have merged (via Metadata uniquing) with the old ones. Dropping the pointers first prevents them from merging. **** The original commit message follows. **** Linker: Drop function pointers for overridden subprograms Instead of dropping subprograms that have been overridden, just set their function pointers to `nullptr`. This is a minor adjustment to the stop-gap fix for PR21910 committed in r224487, and fixes the crasher from PR22792. The problem that r224487 put a band-aid on: how do we find the canonical subprogram for a `Function`? Since the backend currently relies on `DebugInfoFinder` (which does a naive in-order traversal of compile units and picks the first subprogram) for this, r224487 tried dropping non-canonical subprograms. Dropping subprograms fails because the backend *also* builds up a map from subprogram to compile unit (`DwarfDebug::SPMap`) based on the subprogram lists. A missing subprogram causes segfaults later when an inlined reference (such as in this testcase) is created. Instead, just drop the `Function` pointer to `nullptr`, which nicely mirrors what happens when an already-inlined `Function` is optimized out. We can't really be sure that it's the same definition anyway, as the testcase demonstrates. This still isn't completely satisfactory. Two flaws at least that I can think of: - I still haven't found a straightforward way to make this symmetric in the IR. (Interestingly, the DWARF output is already symmetric, and I've tested for that to be sure we don't regress.) - Using `DebugInfoFinder` to find the canonical subprogram for a function is kind of crazy. We should just attach metadata to the function, like this: define weak i32 @foo(i32, i32) !dbg !MDSubprogram(...) { llvm-svn: 233302

DebugInfo: Move new hierarchy into place Move the specialized metadata nodes for the new debug info hierarchy into place, finishing off PR22464. I've done bootstraps (and all that) and I'm confident this commit is NFC as far as DWARF output is concerned. Let me know if I'm wrong :). The code changes are fairly mechanical: - Bumped the "Debug Info Version". - `DIBuilder` now creates the appropriate subclass of `MDNode`. - Subclasses of DIDescriptor now expect to hold their "MD" counterparts (e.g., `DIBasicType` expects `MDBasicType`). - Deleted a ton of dead code in `AsmWriter.cpp` and `DebugInfo.cpp` for printing comments. - Big update to LangRef to describe the nodes in the new hierarchy. Feel free to make it better. Testcase changes are enormous. There's an accompanying clang commit on its way. If you have out-of-tree debug info testcases, I just broke your build. - `upgrade-specialized-nodes.sh` is attached to PR22564. I used it to update all the IR testcases. - Unfortunately I failed to find way to script the updates to CHECK lines, so I updated all of these by hand. This was fairly painful, since the old CHECKs are difficult to reason about. That's one of the benefits of the new hierarchy. This work isn't quite finished, BTW. The `DIDescriptor` subclasses are almost empty wrappers, but not quite: they still have loose casting checks (see the `RETURN_FROM_RAW()` macro). Once they're completely gutted, I'll rename the "MD" classes to "DI" and kill the wrappers. I also expect to make a few schema changes now that it's easier to reason about everything. llvm-svn: 231082

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
