I use arm-coff on x86-linux.
Here is what I do:

1. Make a file called "hello.c"

     #include <stdio.h>
     int main()
     {
       printf("hello\n");
       return(0);
     }


2. Compile the program

     % arm-coff-gcc hello.c -o hello

   The linked executable will be in a file called "hello"


3. Disassemble the program

     % arm-coff-objdump -d hello


4. Simulate the program using the Armulator

     % arm-coff-run hello
     hello


5. Debug the program using the Armulator

     % arm-coff-gdb hello
     (gdb) file hello 
     Reading symbols from hello...done.
     (gdb) target sim
     Connected to the simulator.
     (gdb) load
     Loading section .text, size 0x9480 vma 0x8000
     Loading section .data, size 0xad4 vma 0x40480
     Start address 0x8000
     Transfer rate: 326304 bits in <1 sec.
     (gdb) run
     Starting program: hello 
     hello

     Program exited normally.
