Log:
Add LLVM_FALLTHROUGH annotation after switch
This silences a -Wimplicit-fallthrough warning from clang. GCC does not
appear to warn when the case body ends in a switch.
This is a somewhat surprising but intended fallthrough that I pulled out
from my mechanical patch. The code intends to handle 'Yi' and related
constraints as the 'x' constraint.
