ANSI C requires that a call to an unprototyped function type succeed
...
if the definition has a non-variadic prototype with compatible
parameters. Therefore, the default rule for such calls must be to
use a non-variadic convention. Achieve this by casting the callee to
the function type with which it is required to be compatible, unless
the target specifically opts out and insists that unprototyped calls
should use the variadic rules. The only case of that I'm aware of is
the x86-64 convention, which passes arguments the same way in both
cases but also sets a small amount of extra information; here we seek
to maintain compatibility with GCC, which does set this when calling
an unprototyped function.

Handle "homogeneous aggregates" as required by the ARM AAPCS-VFP ABI.
...
A homogeneous aggregate is an aggregate data structure where after flattening
any nesting there are 1 to 4 elements of the same base type that is either a
float, double, or Neon vector. All Neon vectors of the same size, either 64
or 128 bits, are treated as equivalent for this purpose. When using the
AAPCS-VFP ABI, check for homogeneous aggregates and pass them as arguments by
expanding them into a sequence of their base types. This requires extending
the existing support for expanded arguments to handle not only structs, but
also constant arrays and complex types.

This reverts commit 67d097e1232b7d66f58989c16a45b8a11721f76e.
We found a miscompile with ARM byval, which is still being investigated.
In the meantime, this works around the problem by disabling ARM byval.

Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx should not imply -mno-sse.
...
Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__.
clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much.

We shouldn't keep track of MMX registers "needed" separately from the SSE

registers needed.

The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. The
...
function parameters weren't converted to use the correct type (x86_mmx). Add a
check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for
that function parameter. If so, it coerces the type to be that.

Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if
...
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.

IRgen/ABI/ARM: Trust the backend to pass vectors correctly for the given ABI.
...
- Therefore, we can lower out the NEON wrapper structs and pass the vectors
directly. This makes a huge difference in the cleanliness of the IR after
optimization.
- I will trust, but verify, via future ABITest testing (for APCS-GNU, at
least).

IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed
...
with a non-default-stack-ABI-alignment (of 16).
- This fixes the ABI convenient, but breaks codegen since we now have
underaligned arguments. Marginal improvement overall though, and will be
fixed in next commit.

IRgen/x86_32/Linux: Linux seems to align all stack objects to 4 bytes, unlike

Darwin. Checked vs the handiest Linux llvm-gcc I had around, someone on Linux is
welcome to investigate more.
