Thanks, I'll leave that to you, then. I also noticed the same test is failing on rtems6 (at least with gcc 11). AFAICT the problem is that _GLIBCXX_SIMD_MATH_CALL* macros in simd_math.h expect the named functions to be in std::, but I get such errors as: .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1299: error: 'remainder' is not a member of 'std' .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1299: note: suggested alternatives: [...] .../aarch64-rtems6/include/math.h:346: note: 'remainder' [...] .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1299: note: 'std::experimental::parallelism_v2::remainder' .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1299: error: template argument 1 is invalid [...] .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1328: error: 'fmin' is not a member of 'std'; did you mean 'min'? .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1328: error: 'fmin' is not a member of 'std'; did you mean 'min'? .../aarch64-rtems6/include/c++/11.4.1/experimental/bits/simd_math.h:1328: error: template argument 1 is invalid ISTM that rtems is missing some of the math.h functions expected by libstdc++, but also that even those that are present are not visible in namespace ::std::, where the macros reasonably expect to find them.
