[PATCH] D136106: [clang][RISCV] Set vscale_range attribute based on VLEN

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

> In the original review, I'd mentioned that MinVLEN was sometimes zero. That's still true, but apparently only happens if you specify multiple extensions in the -target_feature string. So, we can at least test "v" and "zve64x" on their own before I go figure out exactly what's going wrong regarding e.g. parsing "+v,+zvl512b".

I think you need to use `-target-feature "v" -target-feature "zvl512b".
