Add `Function::setSubprogram()` and `Function::getSubprogram()`, convenience methods to forward to `setMetadata()` and `getMetadata()`, respectively, and deal in `DISubprogram` instead of `MDNode`. Also add a verifier check to enforce that `!dbg` attachments are always subprograms. Originally (when I had the llvm-dev discussion back in April) I thought I'd store a pointer directly on `llvm::Function` for these attachments -- we frequently have debug info, and that's much cheaper than using map in the context if there are no other function-level attachments -- but for now I'm just using the generic infrastructure. Let's add the extra complexity only if this shows up in a profile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@246339 91177308-0d34-0410-b5e6-96231b3b80d8
This directory contains testcases that the verifier is supposed to detect as malformed LLVM code. Testcases for situations that the verifier incorrectly identifies as malformed should go in the test/Assembler directory.
