Summary:
We've had support for auto upgrading old style scalar TBAA access
metadata tags into the "new" struct path aware TBAA metadata for 3 years
now. The only way to actually generate old style TBAA was explicitly
through the IRBuilder API. I think this is a good time for dropping
support for old style scalar TBAA.
I'm not removing support for textual or bitcode upgrade -- if you have
IR with the old style scalar TBAA tags that go through the AsmParser orf
the bitcode parser before LLVM sees them, they will keep working as
usual.
Note:
%val = load i32, i32* %ptr, !tbaa !N
!N = < scalar tbaa node >
is equivalent to
%val = load i32, i32* %ptr, !tbaa !M
!N = < scalar tbaa node >
!M = !{!N, !N, 0}
