cea0d0ac2b fix cppcorecheck warnings (#703)
* 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

f4a715816c Suppress warnings on VS (#642)
- 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)

9c5e21045d Make gsl::details::throw_exception not copy exception object (#667)
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 (#640)
* 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

Signed-off-by: Damian Jarek <damian.jarek93@gmail.com>

Addition:
- understand STL no exception macro
- use function static variable to set termination handler in kernel mode
- add compile-only tests for no-exception mode

* added termination tests and fixed bugs

* disabled warning C4577 for msvc 2015

95da2fd337 Don't use clang's __builtin_assume as an optimizer hint (#608)
Fixes #607.

Drive-by: use '?:' to contextually convert to bool in the fallback definition of `GSL_ASSUME`

ebe7ebfd85 Reformat files to follow clang-format style (#492)
Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.

This commit only applies "clang-format -i" to files.

16a6a41690 gsl_assert changes: (#452)
* 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.

4e8f95b418 Cleanup include structure, constexpr and noexcept compiler workarounds.
* 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.
