Comment out debug code :)
Select [mem] += Val operations. For constants, we used to get:
mov %ECX, -32768
add %ECX, DWORD PTR [l4_match_start]
mov DWORD PTR [l4_match_start], %ECX
Now we get:
add DWORD PTR [l4_match_start], -32768
For other values we used to get:
mov %EBP, %EDI ;; because the add destroys the value
add %EBP, DWORD PTR [l4_input_len]
mov DWORD PTR [l4_input_len], %EBP
now we get:
add DWORD PTR [l4_input_len], %EDI
Both of these use less registers than the alternative, are faster and smaller.
