There is an implicit size and ordering expectation for defs that seems quite subtle and deserve documentation here.

I also don't see a test which exercise this extra parameter?

flang/lib/Optimizer/Support/KindMapping.cpp
154

somehow unrelated to this patch, but the reference here is unusual, is this needed/useful?

194

Seems like the constructor can fail here, should this be a factory function returning an optional then?
Otherwise the caller can't really know...

Nit: if(defs.empty())

Done

flang/lib/Optimizer/Support/KindMapping.cpp
154

It's required. This is the current cursor position walking through the string.

194

Failure here is catastrophic. I'll change this to an error message with abort semantics.
