* module/mescc/M1.scm (riscv:i-format, riscv:j-format, riscv:u-format): New procedures for RISC-V instruction formats. (info->M1): Use them to switch from !0xAB to M1 weird strings 'AB'. * module/mescc/riscv64/as.scm, lib/linux/riscv64-mes-m2/_exit.c ib/linux/riscv64-mes-m2/_write.c,. lib/linux/riscv64-mes-m2/crt1.M1,. lib/linux/riscv64-mes-m2/syscall.c,. lib/linux/riscv64-mes-mescc/_exit.c,. lib/linux/riscv64-mes-mescc/_write.c,. lib/linux/riscv64-mes-mescc/crt1.c,. lib/linux/riscv64-mes-mescc/syscall-internal.c,. lib/linux/riscv64-mes-mescc/syscall.c,. lib/m2/riscv64/riscv64_defs.M1,. lib/riscv64-mes-mescc/setjmp.c,. lib/riscv64-mes/riscv64.M1: Switch to riscv64 word-based macros. * lib/linux/open.c (open)[!SYS_open]: Add support using openat syscall. * include/linux/riscv64/syscall.h (MAKESTRING, MAKESTRING2, RISCV_SYSCALL): New macros.
