+From: Nick Desaulniers <ndesaulniers@google.com>
+Date: Wed, 26 Aug 2020 15:21:29 +1000
+Subject: lib/string.c: implement stpcpy
+
+LLVM implemented a recent "libcall optimization" that lowers calls to
+`sprintf(dest, "%s", str)` where the return value is used to `stpcpy(dest,
+str) - dest`.  This generally avoids the machinery involved in parsing
+format strings.  `stpcpy` is just like `strcpy` except it returns the
+pointer to the new tail of `dest`.  This optimization was introduced into
+clang-12.
+
+Implement this so that we don't observe linkage failures due to missing
+symbol definitions for `stpcpy`.
+
+Similar to last year's fire drill with: commit 5f074f3e192f
+("lib/string.c: implement a basic bcmp")
+
+The kernel is somewhere between a "freestanding" environment (no full
+libc) and "hosted" environment (many symbols from libc exist with the same
+type, function signature, and semantics).
+
+As H.  Peter Anvin notes, there's not really a great way to inform the
+compiler that you're targeting a freestanding environment but would like
+to opt-in to some libcall optimizations (see pr/47280 below), rather than
+opt-out.
+
+Arvind notes, -fno-builtin-* behaves slightly differently between GCC and
+Clang, and Clang is missing many __builtin_* definitions, which I consider
+a bug in Clang and am working on fixing.
+
+Masahiro summarizes the subtle distinction between compilers justly:
+  To prevent transformation from foo() into bar(), there are two ways in
+  Clang to do that; -fno-builtin-foo, and -fno-builtin-bar.  There is
+  only one in GCC; -fno-buitin-foo.
+
+(Any difference in that behavior in Clang is likely a bug from a missing
+__builtin_* definition.)
+
+Masahiro also notes:
+  We want to disable optimization from foo() to bar(),
+  but we may still benefit from the optimization from
+  foo() into something else. If GCC implements the same transform, we
+  would run into a problem because it is not -fno-builtin-bar, but
+  -fno-builtin-foo that disables that optimization.
+
+  In this regard, -fno-builtin-foo would be more future-proof than
+  -fno-built-bar, but -fno-builtin-foo is still potentially overkill. We
+  may want to prevent calls from foo() being optimized into calls to
+  bar(), but we still may want other optimization on calls to foo().
+
+It seems that compilers today don't quite provide the fine grain control
+over which libcall optimizations pseudo-freestanding environments would
+prefer.
+
+Finally, Kees notes that this interface is unsafe, so we should not
+encourage its use.  As such, I've removed the declaration from any header,
+but it still needs to be exported to avoid linkage errors in modules.
