I don't think this description for RVE is quite right. RVE is for RV32E which is not using compressed ('C') instructions, but using a smaller register file (16 GPRs instead of 32) which is in theory intended for embedded / microprocessor variants. The riscv-elf-psabi-doc describes it as: EF_RISCV_RVE (0x0008): This bit is set when the binary targets the E ABI. -- John Baldwin _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
