+/* Hello world */
+#include <stdio.h>
+int myfunc(int a, int b){
+  int k;
+  k = a + b;

+    m += myfunc(i,j);
+    printf("m is %d\n",m);
+  }

 Compile to Assembler for viewing
-mipsel-none-elf-gcc -S fir.c
+<code>
+mipsel-none-elf-gcc -S hello.c
+</code>
-The output is fir.s which is the assembler code.
+The output assembler code is in hello.s.
 Compile and link ready for simulation with instruction set simulator
-mipsel-none-elf-gcc -o fir -Tidt.ld fir.c
+<code>

 Run the code
-mipsel-none-elf-run fir

 === Analyze ===
-Produce an annoted source code
+Produce an annoted source code showing how often lines are executed.
-gcc -fprofile-arcs -ftest-coverage -o fir fir.c
+<code>
+gcc -fprofile-arcs -ftest-coverage -o hello hello.c

-./fir
+This produces the file hello.c.gcov showing the annotated source file.
