As I understand it, yes, this option is not available for X86. RISC-V publishes [extensions](https://lf-riscv.atlassian.net/wiki/spaces/HOME/pages/16154732/Ratified+Extensions) to the Instruction Set Architecture (ISA). The [usage guide](https://llvm.org/docs/RISCVUsage.html#extensions) describes what LLVM currently supports. As far as I am aware, such a thing does not exist on X86. The [documentation](https://github.com/llvm/llvm-project/blob/db6f627f3fd4072fe1814805653a352694527a91/clang/include/clang/Driver/Options.td#L5913) for the command line switch also explicitly restricts the option to AArch64, Arm and RISC-V. https://github.com/llvm/llvm-project/pull/117402 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
