Here's optimized X86 code for searching the (unsorted) method mapping table:

Input:
EAX = method mapping table
ECX = program counter

Output:
EAX = Result

Code:
    test    eax, eax
    je    L003
L001:
    cmp    ecx, [eax]
    jb    L002
    cmp    ecx, [eax+4]
    jb    L004
L002:
    add    eax, 12
    jne    L001
L003:
    xor    eax, eax
    ret    
L004:
    mov    eax, [eax+8]
    ret
