Fixes for compiler errors when building the tests using Clang 15,
including:
* Use explicit cast to silence Wimplicit-int-float-conversion
warning for conversion of spin count in implementation of
glm::slerp.
* Use GLM_FORCE_MESSAGES instead of removed GLM_MESSAGES for
messages in glm/gtx/hash.hpp, avoiding Wundef warning.
* Encode en dash in URL for Gram-Schmit Process wikipedia page and
replace similar en dashes in comments with regular dashes, to
avoid Winvalid-utf8 warnings in glm/gtx/matrix_factorisation.inl.
* Replace degree sign symbol with text "degrees" to avoid
Winvalid-utf8 warnings in test/gtc/gtc_quaternion.cpp.
* When using Clang, build tests with -Wno-float-equal to silence
Wfloat-equal warning in implementation of glm::vec<L,T,Q>::equal.
* For performance tests in test/gtx/gtx_fast_trigonometry.cpp, add
statement explicitly casting result to void, to silence
Wunused-but-set-variable warnings.
* Add newline at end of test/gtx/gtx_hash.cpp to silence
Wnewline-eof warning.
* Rename namespace _1aga to agarose in test/gtx/gtx_pca.cpp to
avoid Wreserved-identifier warning.
Depending on the developer environment, the output of round for o.5 or -0.5 may be different (according to the GLSL spec). So the test was too restrictive.
The previous patch made the incorrect assumption matrices were row-major
instead of column-major (got the two mixed up in my head).
This fixes this problem.
Also, this extends the test files to cover all matrix sizes (not types,
that would be redundant).
- Add a blank line before block elements (lists, code blocks, etc)
- Remove trailing whitespace
- Use "plaintext" language for code blocks when appropriate
- Fix duplicated section3_4 anchor
- Fix <` to `< in section 4.10
- Always referece images relative to the current directory
- Use markdown-style link instead of HTML href in section 7.13
- Remove extra space before closing emphasis in section 4.18
This is added as part of the GLM_EXT_matrix_common extension, as this
function is not provided by the core GLSL specification (version 4.20).
The implementation of this glm::abs(mat<>) function mirrors the
glm::abs(vec<>) implementation. It should be functionning the same in
every way as the vec implementation.
Bonus points : AFAICT this allows to vectorize operations on compilers
that support optimization of these patterns, just like the functor1<>
struct in _vectorize.hpp for vectors.
Fix warnings on hash functions with GCC and -Wnoexcept:
* Add GLM_HAS_NOEXCEPT flag & GLM_NOEXCEPT #define to setup.hpp.
* Add GLM_NOEXCEPT to hash functions in hash.hpp.
* Add GLM_NOEXCEPT to matrix operator[] accessors.
* Add gtx_hash.cpp and a test to verify all hash overloads compile.
Configure with -DCMAKE_CXX_FLAGS="-Werror -Wnoexcept" to test.
