++// Implementation of functions for SVML vector call legalization.
++//===----------------------------------------------------------------------===//
++//
++// Unlike other VECLIBs, SVML needs to be used with target-legal
++// vector types. Otherwise, link failures and/or runtime failures
++// will occur. A motivating example could be -
++//
++//   double *a;
++//   float *b;
++//   #pragma clang loop vectorize_width(8)
++//   for(i = 0; i < N; ++i) {
++//     a[i] = sin(i);   // Legal SVML VF must be 4 or below on AVX
++//     b[i] = cosf(i);  // VF can be 8 on AVX since 8 floats can fit in YMM
++//    }
++//
++// Current implementation of vector code generation in LV is
++// driven based on a single VF (in InnerLoopVectorizer::VF). This
++// inhibits the flexibility of adjusting/choosing different VF
++// for different instructions.
++//
++// Due to this limitation it is much more straightforward to
++// first generate the illegal sin8 (svml_sin8 for SVML vector
++// library) call and then legalize it than trying to avoid
++// generating illegal code from the beginning.
++//
++// A solution for this problem is to check legality of the
++// call instruction right after generating it in vectorizer and
++// if it is illegal we split the call arguments and issue multiple
++// calls to match the legal VF. This is demonstrated currently for
++// the SVML vector library calls (non-intrinsic version only).
++//
++// Future directions and extensions:
++// 1) This legalization example shows us that a good direction
++//    for the VPlan framework would be to model the vector call
++//    instructions in a way that legal VF for each call is chosen
++//    correctly within vectorizer and illegal code generation is
++//    avoided.
++// 2) This logic can also be extended to general vector functions
++//    i.e. legalization OpenMP decalre simd functions. The
++//    requirements needed for this will be documented soon.

Subject: [PATCH 18/23] Fix compiler-rt atomics build

This is a backport of:

```
commit 7939ce39dac0078fef7183d6198598b99c652c88
Author: Jon Roelofs <jonathan_roelofs@apple.com>
Date:   Fri Nov 17 14:21:57 2023 -0800

    [builtins] Move cfi start's after the symbol name [NFC]

    ... in preparation for diagnosing improperly nested .cfi regions.

    See https://reviews.llvm.org/D155245
```

The ordering of `.cfi_startproc` and the function name in compiler-rt's
`assembly.h` triggers a new diagnostic about improperly nested `.cfi`
regions in Clang 18 onwards. This is fixed in compiler-rt upstream, but
needs to be applied to compiler-rt from LLVM 15 because we're building
it with Clang 18 in some cases.

References to discussions of the issue:

- https://github.com/rust-lang/llvm-project/commit/823883116fdee662a3e150a88e6aad583036ccd3

Subject: [PATCH 19/23] Fix symbol visiblility for compiler-rt builtins on
 MacOS

The symbols in the compiler-rt builtins library are private external by
default on MacOS. We need them to be visible so we can link against them
(e.g. when building libllvmlite.so). This patch makes the symbols
visible when the CMake option `COMPILER_RT_BUILTINS_HIDE_SYMBOLS` is
off. Note that this is an existing option for the compiler-rt build, and
the flags requiring modification in this patch appear to be an
oversight.

Subject: [PATCH 20/23] Build compiler-rt builtins

This enables the build of compiler-rt builtins with the following
changes:

- Add `compiler-rt` to the list of LLVM projects to build
- Disable the build of all `compiler-rt` components except for the
  builtins. Whilst it would be interesting to add these, they seem to
  require clang to be built at the same time.
- Setting the `COMPILER_RT_BUILTINS_HIDE_SYMBOLS` CMake option to `OFF`,
  to ensure that we can link against those symbols in the general case.

Note that these changes are simpler than previous efforts towards
enabling `compiler-rt` builtins (e.g. #979) - this is because we now
build as part of the whole `llvm-project` tree, which simplifies things
and removes issues that had to be worked around when building it
separately.
