Amara Emerson b956051415 [AArch64][GlobalISel] Legalization and ISel support for load/stores of vectors of pointers.
Loads and store of values with type like <2 x p0> currently don't get imported
because SelectionDAG has no knowledge of pointer types. To leverage the existing
support for vector load/stores, we can bitcast the value to have s64 element
types instead. We do this as a custom legalization.

This patch also adds support for general loads of <2 x s64>, and relaxes some
type conditions on selecting G_BITCAST.

Aaron Smith fa7745be7a [DebugInfo] Combine Trivial and NonTrivial flags
Summary:
These flags are used when emitting debug info and needed to initialize subprogram and member function attributes (function options) for Codeview. These function options are used to create an accurate compiler type for UDT symbols (class/struct/union) from PDBs.

The Trivial flag was introduced in https://reviews.llvm.org/D45122

It's been pointed out that Trivial and NonTrivial may imply each other and that seems to be the case in the current tests. This change combines them into a single flag -- NonTrivial -- and updates the corresponding unit tests. There is an additional change to llvm to update the flags.

Craig Topper 68a5d619a4 [X86] Restrict vselect handling in scalarizeExtEltFP to only case to pre type legalization where the setcc result type is vXi1.
If the vector setcc has been legalized then we will need to convert a vector boolean of 0 or -1 to a scalar boolean of 0 or 1.

The added test case previously crashed in 32-bit mode by creating a setcc with an i64 condition that type legalization couldn't expand.

Craig Topper 586fad50ac [X86] Add patterns for using movss/movsd for atomic load/store of f32/64. Remove atomic fadd pseudos use isel patterns instead.
This patch adds patterns for turning bitcasted atomic load/store into movss/sd.

It also removes the pseudo instructions for atomic RMW fadd. Instead just adding isel patterns for folding an atomic load into addss/sd. And relying on the new movss/sd store pattern to handle the write part.

This also makes the fadd patterns use VEX and EVEX instructions when AVX or AVX512F are enabled.

Craig Topper f7e548c076 Recommit r358211 "[X86] Use FILD/FIST to implement i64 atomic load on 32-bit targets with X87, but no SSE2"
With correct test checks this time.

If we have X87, but not SSE2 we can atomicaly load an i64 value into the significand of an 80-bit extended precision x87 register using fild. We can then use a fist instruction to convert it back to an i64 integ

This matches what gcc and icc do for this case and removes an existing FIXME.

If we have X87, but not SSE2 we can atomicaly load an i64 value into the significand of an 80-bit extended precision x87 register using fild. We can then use a fist instruction to convert it back to an i64 integer and store it to a stack temporary. From there we can do two 32-bit loads to get the value into integer registers without worrying about atomicness.

Louis Dionne 7c142fcc06 [libc++] Make sure we don't eagerly diagnose non-const comparators for containers of incomplete types
Summary:
In r348529, I improved the library-defined diagnostic for using containers
with a non-const comparator/hasher. However, the check is now performed
too early, which leads to the diagnostic being emitted in cases where it
shouldn't. See PR41360 for details.

This patch moves the diagnostic to the destructor of the containers, which
means that the diagnostic will only be emitted when the container is instantiated
at a point where the comparator and the key/value are required to be complete.
We still retain better diagnostics than before r348529, because the diagnostics
are performed in the containers themselves instead of __tree and __hash_table.

As a drive-by fix, I improved the diagnostic to mention that we can't find
a _viable_ const call operator, as suggested by EricWF in PR41360.

Roger Ferrer Ibanez b621f04135 [RISCV] Diagnose invalid second input register operand when using %tprel_add
RISCVMCCodeEmitter::expandAddTPRel asserts that the second operand must be
x4/tp. As we are not currently checking this in the RISCVAsmParser, the assert
is easy to trigger due to wrong assembly input.

This patch does a late check of this constraint.

An alternative could be using a singleton register class for x4/tp similar to
the current one for sp. Unfortunately it does not result in a good diagnostic.
Because add is an overloaded mnemonic, if no matching is possible, the
diagnostic of the first failing alternative seems to be used as the diagnostic
itself. This means that this case the %tprel_add is diagnosed as an invalid
operand (because the real add instruction only has 3 operands).

// bo (build_vec ...undef, x, undef...), (build_vec ...undef, y, undef...) -->
// build_vec ...undef, (bo x, y), undef...

The lifetime of the nodes in these examples is different for variables versus constants,
but they are all build vectors briefly, so I'm proposing to catch them in this form to
handle all of the leading examples in the motivating test file.

Before we have build vectors, we might have insert_vector_element. After that, we might
have scalar_to_vector and constant pool loads.

It's going to take more work to ensure that FP vector operands are getting simplified
with undef elements, so this transform can apply more widely. In a non-loose FP environment,
we are likely simplifying FP elements to NaN values rather than undefs.

We also need to allow more opcodes down this path. Eg, we don't handle FP min/max flavors
yet.
