These are triggering a bad compile-time regression for some expressions; that's a bug that should be fixed, but we don't know how to fix it yet, so we'll need to remove these in the short-term, and possibly spell them differently in the medium term.
The purpose of this module is to prespecialize generic methods in the
stdlib. All symbols exposed by the ABI must be explicitly identified
to maintain ABI compatibility. Some of those ABI-exposed symbols
reference internal stdlib types.
Given that we want the prespecialized code to live in the separate
SwiftOnoneSupport library, and we want the module to explicitly list
all the symbols required for ABI stability, there's no way around
disabling access control when building it. In fact, that flag does
precisely what we want.
This should be harmless because
- no one imports SwiftOnoneSupport.swiftmodule
- these internal symbols were always being exposed in
SwiftOnoneSupport.dylib, so nothing changes there
* Additions to SIMD types.
- extension from 2 and 3-element vectors to 3- and 4-element vectors.
- the .one member
- swizzles via subscript-by-simd
- min/max/sum reductions
- min/max/clamp on vectors-of-comparable
- any and all
- Make permute subscript wrap on vector length, even for SIMD3 dictionaries. Also restore min/max to globals, rather than static functions.
The sections to which the start/stop symbols are being applied do not
guarantee pointer alignment. In particular, the field metadata is
aligned to a 4-byte boundary, which is less then the pointer alignment
of `uintptr_t`. This results in extra padding in the data which is
going to cause the iteration to run off the end. A similar byte
alignment is forced for the markers in the ELF case as well. This fixes
one of the reflection tests on Windows where we were attempting to
decode the padding as an entry.
The new definition diverges from the existing hashValue: it feeds all path components to the hasher, rather than just a limited subset.
Hashing all the bits that are compared in == is necessary to ensure proper operation of the hash table.

Since we use `_hypotf` on Windows rather than `__builtin_hyptof` due to
a bug in LLVM with the TLI lowering to the wrong builtin, include the
math header to get the proper declaration.
