• Convert pseudo-instructions into actual hardware instructions – pseudo-instrs make it easier to program in assembly – examples: “move”, “blt”, 32-bit immediate operands, etc. • Convert assembly instrs into machine instrs – a separate object file (x.o) is created for each C file (x.c) – compute

the length of the C string cstr. • Implement the C library function strcpy(dst, src), which copies the characters from the string src into the character array indicated by dst. For example, the code on the left should generate the memory state on the right: char *msg = "hello, world"; char buffer[16]; msg h e l …

Obtaining a C-style char * from a string Remember, a C++ string is not the same thing as a C-style string (which is merely a char * pointer to a sequence of characters terminated by a null character '\0'). Although old-style C char * strings and C++ strings can co-exist in a program, almost all
