Yeah, it's described in the [PR](https://github.com/riscv-non-isa/riscv-elf-psabi-doc/pull/418/files#diff-3a934f00cffdb3e509722753126a2cf6082a7648ab3b9ca8cbb0e84f8a6a12edR464-R466), basically this option won't affect functions that don't have `riscv_vls_cc` keyword specified, and I believe it provides a way for user to write `ABI_VLEN` agnostic code, but yeah it's easier to break the code if we don't handle carefully. https://github.com/llvm/llvm-project/pull/100346 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
