Update more file headers across all of the LLVM projects in the monorepo

2019-01-19T10:56:40+00:00

to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

[libcxx] Call __count_bool_true for bitset count

2019-01-11T17:31:17+00:00

This patch aims to help clang with better information so it can inline __bit_reference count function usage for both std::biset. Current clang inliner can not infer that the passed typed will be used only to select the optimized variant, it evaluates the type argument and type check as a load plus compare (although later optimization phases correctly optimized this out). It is mainly to help llvm inliner to generate better code for std::bitset count for aarch64. It helps on both runtime and code size, since if inline decides that _VSTD::count should not be inlined the vectorization will create both aligned and unaligned variants (which add both code size and runtime costs) llvm-svn: 350936

[Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows

2017-05-31T22:07:49+00:00

Summary: This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning. This patch changes libc++ to use `#pragma push_macro` to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.

[NFC] Rename _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS

2017-01-04T23:56:00+00:00

The name _LIBCPP_TYPE_VIS_ONLY is no longer accurate because both _LIBCPP_TYPE_VIS and _LIBCPP_TYPE_VIS_ONLY expand to __attribute__((__type_visibility__)) with Clang. The only remaining difference is that _LIBCPP_TYPE_VIS_ONLY can be applied to templates whereas _LIBCPP_TYPE_VIS cannot (due to dllimport/dllexport not being allowed on templates). This patch renames _LIBCPP_TYPE_VIS_ONLY to _LIBCPP_TEMPLATE_VIS. llvm-svn: 291035

Avoid narrowing warnings in __bitset constructor

When is compiled with warnings enabled, on a platform where size_t is 4 bytes, it results in errors similar to: bitset:265:16: error: non-constant-expression cannot be narrowed from type 'unsigned long long' to '__storage_type' (aka 'unsigned int') in initializer list [-Wc++11-narrowing] : __first_{__v, __v >> __bits_per_word} ^~~ bitset:676:52: note: in instantiation of member function 'std::__1::__bitset<2, 53>::__bitset' requested here bitset(unsigned long long __v) _NOEXCEPT : base(__v) {} ^ Fix these by casting the initializer list elements to __storage_type.
