(simd_clone_adjust_sve_vector_type): New helper function. (aarch64_simd_clone_adjust): Add '+sve' attribute to SVE simd clones and modify types to use SVE types. * omp-simd-clone.cc (simd_clone_mangle): Print 'x' for VLA simdlen. (simd_clone_adjust): Adapt safelen check to be compatible with VLA simdlen. gcc/testsuite/ChangeLog: PR target/96342 * gcc.target/aarch64/declare-simd-2.c: Add SVE clone scan. * gcc.target/aarch64/vect-simd-clone-1.c: New test. * g++.target/aarch64/vect-simd-clone-1.C: New test.
