* initializer_list overload returns by value to avoid lifetime issues
* generic overload uses expression SFINAE to work with any type that has member size() and operator[], which notably includes const/non-const vector and array.
* Add test coverage for const objects, rvalue initializer_lists, and constexpr usage.
Fixes#357.
* Improve const correctness in string_span
* Improve const correctness in bounds_tests.cpp and byte_tests.cpp
* Improve const correctness in span_tests.cpp
* Improve const correctness in utils_tests.cpp
* Use gsl::owner for dynamically allocated memory in string_span_tests.cpp
* Improve const correctness in string_span_tests.cpp
* Improve const correctness for strided_span_tests.cpp
* CI updates:
Travis: use cmake 3.7
Appveyor: Add .appveyor.yml config, test VS2013/VS2015/VS2017 x86/x64 Debug/Release.
* Drop VS2013 support from AppVeyor.
* GSL_LIKELY/_UNLIKELY always contextually convert their argument to bool.
* Add macro GSL_ASSUME(cond) to inform the optimizer that the predicate cond must hold.
* Reimplement Expects & Ensures as expressions for flexibility and correctness. (Think about "if (cond1) Expects(cond2); else goto fail;")
* Expects and Ensures GSL_ASSUME their predicate when GSL_UNENFORCED_ON_CONTRACT_VIOLATION is defined.
* add gsl::not_null operator<<
Hippomocks, which is a popular mocking engine for C++ uses operator<< on pointers and gets confused about gsl::not_null not having this operator.
* Update gsl
* Update README.md
edited link to the `gsl` include directory
* Update README.md
added `include` to the include path according to the directory structure
* constexpr all the things.
* remove operator=(const T&)
* it leaves *this in an invalid state if ensure_invariant fails
* implicitly converting the T to not_null and then assigning is in every way superior.
* simplify conversion from not_null<U> with constructor delegation.
* remove the converting assignment operator; again let the conversion constructor and self-assignment operator do the work.
* Cover the remaining pointer arithmetic operations as Wakely suggests in issue #447.
* Cleanup not_null conversions from null pointer constants:
* replace constructor that accepts T with constructor template that accepts U convertible to T
* remove deleted constructor that accepts int
* Attempts to initialize with nullptr, 0, 0L, 0LL, etc. all unambiguously select the deleted nullptr_t constructor.
Now that the STL respects /W4, this test that uses std::copy_n to copy a span of ints to a span of chars triggers "warning C4244: '=': conversion from 'int' to 'char', possible loss of data". Switch the source & destination spans to short and int to maintain the test's cross-type nature but without narrowing.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.
This patch provides a make_span function to simplify the
creation of spans until C++17 is available. In addition
this patch updates the unit tests to includes tests that
verify this new functionality.
This patch adds support for std::unique_ptr and
std::shared_ptr to the gsl::span
class instead of having to manually grab the pointer via
get().
For reference, this is part of the following issue:
https://github.com/Microsoft/GSL/issues/402
When turning on the following flags, several additional warnings
were generated, which have been cleaned up in this patch. The
flags included:
-Wextra
-Wpedantic
-Wconversion
-Wsign-conversion
-Wctor-dtor-privacy
-Wshadow
-Wnon-virtual-dtor
-Wold-style-cast
-Wcast-align
-Woverloaded-virtual
This patch fixes an overflow that was identified with
strict overflow warnings enabled, and optimizations
turned on

'make install' should install the GSL library (ie. the headers),
not the tests.
It still installs the UnitTest++ headers, but that will be more
complex to fix, as GSL just imports UnitTest++ as a git submodule,
and the install command propagates down to UnitTest++'s
CMakeLists.txt.
* Add test to demonstrate byte aliasing problem on g++ and clang++
* Add note about no-strict-aliasing flag in README
* Activate aliasing unit test and use -fno-strict-aliasing flag
Cygwin recently did an update that broken string_span again. The original update had to provide a custom strnlen function because Cygwin doesn't implement this (it's a non-std extension). We never added wchar_t support, and the Cygwin update now breaks on exactly this. This patch provides the missing wchar_t.
