rjmccall added a subscriber: t.p.northover. rjmccall added a comment. @t.p.northover says it's complicated. `memcpy`, `memmove`, `memset`, and `bzero` are (I think) the only ones that LLVM will potentially synthesize from nothing and therefore need to be present even in freestanding builds; that's probably okay for us to guarantee. That's probably also a good place to document the supported way to write those functions in libraries (just `-fno-builtin`, IIRC?).
In hosted builds, we should document that we assume the existence of the standard C library for the target platform, potentially including non-standard functions like `exp10`.
