Duncan P. N. Exon Smith 1545953510 IR: Stop using DIDescriptor::is*() and auto-casting ... `DIDescriptor`'s subclasses allow construction from incompatible pointers, and `DIDescriptor` defines a series of `isa<>`-like functions (e.g., `isCompileUnit()` instead of `isa<MDCompileUnit>()`) that clients tend to use like this: if (DICompileUnit(N).isCompileUnit()) foo(DICompileUnit(N)); These construction patterns work together to make `DIDescriptor` behave differently from normal pointers. Instead, use built-in `isa<>`, `dyn_cast<>`, etc., and only build `DIDescriptor`s from pointers that are valid for their type. I've split this into a few commits for different parts of LLVM and clang (to decrease the patch size and increase the chance of review). Generally the changes I made were NFC, but in a few places I made things stricter if it made sense from the surrounded code. Eventually a follow-up commit will remove the API for the "old" way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234255 91177308-0d34-0410-b5e6-96231b3b80d8		2015-04-06 23:18:49 +00:00
