[x86][FastISel] Teach how to select nontemporal stores.

This patch teaches x86 fast-isel how to select nontemporal stores.

On x86, we can use MOVNTI for nontemporal stores of doublewords/quadwords.
Instructions (V)MOVNTPS/PD/DQ can be used for SSE2/AVX aligned nontemporal
vector stores.

Before this patch, fast-isel always selected 'movd/movq' instead of 'movnti'
for doubleword/quadword nontemporal stores. In the case of nontemporal stores
of aligned vectors, fast-isel always selected movaps/movapd/movdqa instead of
movntps/movntpd/movntdq.

With this patch, if we use SSE2/AVX intrinsics for nontemporal stores we now
always get the expected (V)MOVNT instructions.
The lack of fast-isel support for nontemporal stores was spotted when analyzing

[CMake] Set Policy CMP0048 to NEW

This makes overriding LLVM_VERSION_* not work properly with newer versions of CMake. To make this work properly we need to:

(1) Optionally set the policy to NEW

(3) If the policy is set, pass the VERSION and LANGUAGES options in the new format

The issue with the malformed-machos 00000031.a test is that it needed ‘-arch x86_64’

The default as to which architecture slice that is dumped without an -arch flag
depends on the host architecture and the contents of the universal file.  The
malformed archive 00000031.a file has both an x86_64 and i386 slice.  So for
for x86_64 hosts only that slice is dumped, for non-x86_64 hosts, which is many
of the bots both slices are dumped.

The test is intended to only check that the malformation of the x86_64 which
has a non-decimal characters in the size field of the archive header so it no
longer crashes.

The problem turned out that the i388 slice of the malformed archive had a
different malformation which was causing the non-x86_64 bots to get this error:

and causing the test as it was written to fail.  So by adding ‘-arch x86_64’ it
should correct the test and the malformation on the i388 slice will not be
dumped.

Floating point operations don't set flags, the subsequent fadd

9 years ago[x86] Fix wrong lowering of vsetcc nodes (PR25080).
Andrea Di Biagio [Mon, 12 Oct 2015 19:22:30 +0000 (19:22 +0000)]
[x86] Fix wrong lowering of vsetcc nodes (PR25080).

Function LowerVSETCC (in X86ISelLowering.cpp) worked under the wrong
assumption that for non-AVX512 targets, the source type and destination type
of a type-legalized setcc node were always the same type.

This assumption was unfortunately incorrect; the type legalizer is not always
able to promote the return type of a setcc to the same type as the first
operand of a setcc.

In the case of a vsetcc node, the legalizer firstly checks if the first input
operand has a legal type. If so, then it promotes the return type of the vsetcc
to that same type. Otherwise, the return type is promoted to the 'next legal
type', which, for vectors of MVT::i1 is always a 128-bit integer vector type.

Example (-mattr=+avx):

  %0 = trunc <8 x i32> %a to <8 x i23>
  %1 = icmp eq <8 x i23> %0, zeroinitializer

The initial selection dag for the code above is:

v8i1 = setcc t5, t7, seteq:ch
  t5: v8i23 = truncate t2
    t2: v8i32,ch = CopyFromReg t0, Register:v8i32 %vreg1
    t7: v8i32 = build_vector of all zeroes.

The type legalizer would firstly check if 't5' has a legal type. If so, then it
would reuse that same type to promote the return type of the setcc node.
Unfortunately 't5' is of illegal type v8i23, and therefore it cannot be used to
promote the return type of the setcc node. Consequently, the setcc return type
is promoted to v8i16. Later on, 't5' is promoted to v8i32 thus leading to the
following dag node:
  v8i16 = setcc t32, t25, seteq:ch

  where t32 and t25 are now values of type v8i32.

Before this patch, function LowerVSETCC would have wrongly expanded the setcc
to a single X86ISD::PCMPEQ. Surprisingly, ISel was still able to match an
instruction. In our case, ISel would have matched a VPCMPEQWrr:
  t37: v8i16 = X86ISD::VPCMPEQWrr t36, t25

However, t36 and t25 are both VR256, while the result type is instead of class
VR128. This inconsistency ended up causing the insertion of COPY instructions
like this:
  %vreg7<def> = COPY %vreg3; VR128:%vreg7 VR256:%vreg3

Which is an invalid full copy (not a sub register copy).
Eventually, the backend would have hit an UNREACHABLE "Cannot emit physreg copy
instruction" in the attempt to expand the malformed pseudo COPY instructions.

This patch fixes the problem adding the missing logic in LowerVSETCC to handle
the corner case of a setcc with 128-bit return type and 256-bit operand type.

This problem was originally reported by Dimitry as PR25080. It has been latent
for a very long time. I have added the minimal reproducible from that bugzilla
as test setcc-lowering.ll.
