1 # Assembly code for making mips64 syscalls. 2 # 3 # mips64 syscall argument register ordering is the same as the mips64 4 # userspace argument register ordering except that the syscall number 5 # (nr) is passed in v0. 6 # 7 # outline.rs takes care of reordering the nr argument to the end for us, 8 # so we only need to move nr into v0. 9 10 .file "mips.s" 11 .section .mdebug.abi32 12 .previous
