--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Patch for the C/C++ parser side:
https://gcc.gnu.org/pipermail/gcc-patches/2026-October/733488.html
TODO (once it landed):
* Middle end handling, including target hook update and
mangling of 'declare simd' cloned functions.
* Fortran support for simdlen's 'scaled'
* Doing something about the '__simd__' attribute (C/C++ and Fortran's 'simd')
to work with GLIBC's vector math functions
