Hi, I am trying to rewrite the arm assembly code generated by gcc in release mode (for optimization purpose). The below code is in a loop and so it will get executed many times. Can some one please let me know how can I optimize it for cycles. Are there any bottle necks in this code? Thanks in advance..
Assembly code:
ldr r4, [r1, #8] ldr r6, [r1] ldr r7, [r7, #-12] and r11, r4, #7 ldr r6, [r6, r4, lsr #3] rev r6, r6 lsl r6, r6, r11 lsr r6, r6, #23 lsl r6, r6, #2 add r11, r7, r6 ldrsh r6, [r7, r6] ldrsh r7, [r11, #2] add r4, r7, r4 ldr r7, [r1, #16] cmp r4, r7 strls r4, [r1, #8] strhi r7, [r1, #8]
