* Added c++17 test configurations for clang5.0 and clang6.0
* Added optimization that removes a branch from span::operator[]
* minor beauty fix
* added a better message for the optimization, fixed signed/unsigned warning
* better check fir wrap-around possibility
* Added c++17 test configurations for clang5.0 and clang6.0
* Added make_not_null helper to create a not_null
Introduction of explicit not_null constructor made it cumbersome to create not_nulls
in c++14. Adding make_not_null helper. Usage (see tests):
int i = 42;
auto x = make_not_null(&i);
helper(make_not_null(&i));
helper_const(make_not_null(&i));
* Added std::forward to make_not_null, fixed some code analysis warnings
* Fix build break in VS2015 Release configuration
* Fix build break in VS2015 Release configuration
* Added c++17 test configurations for clang5.0 and clang6.0
* Fixed CppCoreCheck warnings in GSL and tests
- Added CMakeSettings.json for VS Open Folder configuration
- So we can easily run CppCoreCheck in VS
- Fixed CppCorecheck warnings where it made sense
- Suppressed the rest
- Some suppression does not work due to compiler/tool bugs,
so replaced by #pragma disable
- CppCoreCheck has noise, suppressed those with comments
- Catch produces many warnings, blanket-supressed them all
- Had to fix clang formatting to keep attributes in place
- clang-format does not support attributes, so I am using
- "CommentPragmas: '^ NO-FORMAT:'" to skip formatiting on them
- Removed GSL_NOEXCEPT macro, removed incorred noexcepts
* Ignore unknown attributes
* ignore unknown attributes in noexception mode tests
* fixed C26472 in at()
* created GSL_SUPPRESS macro to allow all compilers to parse suppression attributes
* try to fix gcc compilation problems with attributes
* ignore gsl::suppress for gcc
* move suppression to function level on return statements
clang5.0 and up does not allow attributes on return statemets in constexpr functions
* move suppression to function level on return statements
* use GSL_SUPPRESS in algorithm_tests
* Addressed PR comments
* Added c++17 test configurations for clang5.0 and clang6.0
* removed GSL_NOEXCEPT
- Removed GSL_NOEXCEPT macro
- Replaced by noexcept keyword when needed
- removed noexcept where a function could throw
* remove unneded undef
* fixed replace errors
* removed noexcept where function can throw
* Explicitly check for availbility of std::byte
GCC > 7.3 defines __cpp_lib_byte >= 201603 when std::byte is available.
On libc++ std::byte is available since version 5.0. This can be checked
with _LIBCPP_VERSION >= 5000.
This fixes 713.
* Add missing \ in preprocessor check
- gsl::narrow, gsl::narrow_cast and gsl::at are the safe variants suggested by CppCoreGuideline. It does not make sense to let VS warn inside the implementation of these functions that unsafe static_cast is used and that the safe variants shall be used.
- Suppress warning that throw_exception can be declared noexcept (for the GSL_TERMINATE_ON_CONTRACT_VIOLATION case)
* Added template argument deduction for not_null
This allows compilers with c++17 support to infer template
instantiation types when calling not_null constructor:
int foo(not_null<const int*> x);
int main()
{
int t = 0;
not_null x{ &t };
return foo(not_null{ &t });
}
* replaced deduction guides by a simple constructor
* Updated tests
* fixed check for availability of std::byte
* testing c++1z on clang
* fixed cmakelists extra endif
* include cstddef header for clang and gcc in pointers
* fixed a typo
* fix missing nullptr_t type
* fixed typo in CMakeLists.tst
* change approach to c++17 testing, step one: revert cmake testing, update clang5.0 package
removed using latest c++ due to clang5.0 failing,
update clang5.0 travis config to use llvm-toolchain-trusty-5.0
* addressed comments
* Add usage for check-and-unwrap of MS STL iterators
This is Billy ONeal's PR #682 with a typo fixed.
See corresponding change here:
ca77129308
That change officially exposes the STL's range checking machinery,
available in MSVC++ "15.8"+
This change augments GSL span::iterator to call into that newly exposed
machinery.
_Verify_range(cit, cit)
Requests that the iterator type check that the parameters form a valid
[First, Last) range iterator pair. This replaces _DEBUG_RANGE and
supporting machinery. The standard library provides a version for
pointers under _IDL != 0; otherwise they are normally provided via
hidden friend functions. Note that declaring some of these hidden
friends for "wrapper" iterators like move_iterator and reverse_iterator
triggers VSO#610735.
cit._Verify_offset(difference_type _Off)
For random-access iterators, performs any asserts that would be
performed by i += _Off; except with possibly a better error message and
without moving the iterator.
cit._Unwrapped()
Returns an "unchecked" or "unwrapped" iterator which has previously been
validated. The iterator may have been validated by a call to
_Verify_range or _Verify_offset (above), or by seeking a checked
iterator to a "high water mark" point.
it._Seek_to(cit) / it._Seek_to(return value from _Unwrapped())
Moves the position of the checked iterator it to the position of the
unchecked iterator supplied. Generally not intended to perform range
checks.
* Fixed build break in VS2015
* fixed constexpr build break when using VS2015
* [span] implement non-member + as a hidden friend
Drive-by: remove garbage `operator-(difference_type, span_iterator)`.
* [span] Use pointers for range-based-for on MSVC
C++17 defines `std::byte*` to have the same aliasing properties as
`char*`. Hence, we mark it with the `__may_alias__` attribute under gcc
and clang.
Based on the fix by Martin Moene in byte-lite.
Fixes#663
This fixes the build with clang 7 which introduces a new warning
`-Wreturn-std-move` which warns about needless copies when a move
operation is available (see https://reviews.llvm.org/rL329914).
We take the exception object by uref so we should throw the forwarded
version.
* Enable usage of gsl::narrow with exceptions disabled
This solution uses the approach of boost::asio to enabling usage of the
library in environments where exception usage is either prohibited
or not feasible (due to code size constraints). A function template
gsl::throw_exception has been added, which in a normal environment just
throws the exception. However, when GSL_TERMINATE_ON_CONTRACT_VIOLATION
is defined the function is only declared by gsl and the definition of
this function template must be supplied by the library's user.
Closes: #468
