I want to write an SVE/SVE2 code (assembly and/or C intrinsic) code. Which version of GNU supports SVE / SVE2? I am also interested in auto-vectorization if that is supported.

SVE assembly/disassembly/auto-vectorization is supported in GCC 8.x onwards. SVE C intrinsics (also known as ACLE) is supported in GCC 10.x.

SVE2 assembly/disassembly/auto-vectorization/C-intrinsics is supported in GCC10.x onwards.
