* Added support for returning fixed-spize spans from subspan().
* Addressed issues from code review.
* Took simpler approach to static data member.
* Subtle fix to support MSVC 15.
* Helps to not introduce extraneous >
* fixed noexept warnings
- Removed conditional compilation for throwing version of GSL
vs fail_fast because we don't want users of the code to see
differences in the span interface dependent on error mechanism
chosen
- Removed noexcept from functions that may fail at runtime
- Fixed CppCoreCheck warnings related to missing and incorrect
noexcept
- do not warn on unnown attributes for GCC and Clang
* remove suppress that does not compiler for clang and gcc
`CMAKE_VERSION_MAJOR` is just the first component of the CMake version (e.g. 3 for 3.10.1) which compares less than `3.7.9` if it is less than 3. The proper variable to compare is `CMAKE_VERSION` which contains the full version number.
Resolves compiler code analysis warning ...\gsl\include\gsl\string_span(101): warning C26496: The variable 'str_span' is assigned only once, mark it as const (con.4: https://go.microsoft.com/fwlink/p/?LinkID=784969).
changes:
- minimal cmake version updated to 3.7(first version with .natvis file handling)
- updated cmake version in readme file
- GSL.natvis file is added only to VS projects
* rewrite span subspan checks to help optimizations
* Removed checking pointer for null for subspans. We would never
check pointer for null in between ptr and ptr+size in the
original span, so there seems to be no reason to do so for
subspans, provided that the subspan's boundaries are ensured
to be within the range of the original span's boundaries.
This change allows to simplify generated code, for example, to
remove 5 out of 9 branches in code generated from the following
by MSVC, and 4 out 8 branches in clang and gcc-generated code:
span<int> mysubspan(int* p, std::ptrdiff_t size, std::ptrdiff_t i)
{
if (p != nullptr)
{
span<int> s = { p, size };
return s.subspan(i);
}
return { nullptr };
}
Similar effects are achieved for dynamic subspans of static spans,
where in the following code we remove 2 out of 4 branchs in MSVC
and GCC-generated code:
int test_dynamic_subspan_of_static_span(std::ptrdiff_t i)
{
int x[] = { 0,1,2,3,4,5 };
span<int, 6> s = { x };
auto subspan = s.subspan(i);
return subspan.size();
}
* travis.yml clean up
- Remove trailling spaces
- Move notification setting from the bottom to the top
- Set Linux as default OS
- Simplify cache directory
- Add banners around different configurations
* Update CMake installation routine
- Make it depend on variable (easier to update)
- Simplify code a bit
* Re-organize build matrix and LLVM install
- make logic depend on a single COMPILER variable
- Update LLVM installation process
* Update compilers to latest stable version
* Made string_span details::string_length() generic
removed overloads & specialized classes
Creating string_spans using `char16_t` and `char32_t` was not possible
without creating new specializations and function overloads.
This patch makes details::string_length() generic removing the need to
extend the overloads and specializations.
* added type aliases for string_span types char16_t and char32_t
* Added char16_t & char32_t overloads for ensure_z
* added string_span tests for char16_T & char32_t
* added zstring type aliases for char16_t & char32_t
* Added tests for char16_t & char31_t zstring and string_span types
* applies clang format to <gsl/string_span>
* Clang format tests/string_span_tests.cpp
* Removed ensure_z() overloads as they don't add functionality.
using the GSL with MSVC 2017 causes the following warning"
`'std::copy_n::_Unchecked_iterators::_Deprecate': Call to 'std::copy_n'`
This patch removes this since the point of this code is to deal with this issue.
