This should build a separate set of embedded runtime libraries, supporting the
option product:
{PIC, static} x { Hard-float, soft-float }
The emphasis is on ARM platforms (Cortex-M4F, Cortex-M3, Cortex-M0) but X86
variants are also built where possible.

DataFlowSanitizer is a generalised dynamic data flow analysis.
Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own. Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

restriction from the GCDAProfile.c"
Bill added a much more effective way of coping with the use of errno and
other system interactions for Darwin for now by disabling it on that
platform. Building against the SDK stuff is more fundamental to the
darwin build process.

darwin.
After talking with Jim Grosbach pretty extensively, he was OK with me
punting on this to the Apple folks.
We agreed that the correct fix is either to extend the fake SDK headers
in compiler-rt to support the rest of libc needed by GCDAProfiling.c or
to teach the make build to test for the existence of a suitable SDK on
the system prior to building it. Both of these require someone with
access to the SDK which I don't have, and the latter (my preferred
solution) requires understanding the strange compiler-rt make build
system. Punting to Dan Dunbar or one of the others who support this
stuff on ios to write the appropriate fix, and we can let the build bots
proceed in the mean time.

runtime in the Makefile build system as well. Sorry for the temporary
fallout, it took me a while to find these bits.
Bill, I'm not at all confident of the change for Darwin and iOS, but as
discussed we're completely blocked on fixing this. Anyways, please
review and let me know if this will work for you guys. If necessary,
I can work with you to rig up an errno.h stub for Darwin, but I expect
that to be... moderately challenging.

the build right from the start.
For now, it is only done with DEBUGMAKE is provided. That makes
things harder to debug during ports of compiler-rt on other systems.

When building compiler-rt on Linux, the "which sw_vers" check fails and
writes an error message into the build log. Apparently on Solaris "which"
writes the error message to stdout, so that the current test won't even
work properly. As far as I know sw_vers always lives in /usr/bin, so just
check for it there instead of using "which".

We now rely on the -mios-simulator-version-min option to identify the iOS
simulator target. I'm not sure if there's anything in compiler-rt where that
matters, but it's the right thing to do regardless.

* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
sanitizer runtime is present.
* libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
a C++ ABI library, and is always linked in.
* libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
C++ ABI library, and is only linked in when linking a C++ binary.
The Darwin ubsan runtime is unchanged.
