In a loop, there has to be atleast 4 iterations to justify the conversion Remove the last iteration of the loop, to use with the Start, Stop instructions Here, I have described a very basic example of how my algorith implementation works

No Repeats - Example

NOP v0 NOP v1 NOP v2 NOP v1 NOP v2 NOP v1 NOP v2 NOP v1 NOP v2 NOP v1 NOP v2 EXIT v3

STI 3 v1 # Loop Count - 1 L: NOP v2 JNI L v1 # Last iteration is not part of the loop NOP v2

Example - Repeats in the beginning only

IDXI 3 v1 NOP v2 IDXI 3 v1 NOP v2 IDXI 3 v1 NOP v2 IDXI 3 v1 NOP v2

STI 3 v1 # Loop Count - 1 L: IDXI 2 v1 # Repeat Count - 1 of beginning NOP v2 JNI L v1 # Last iteration is not part of the loop IDXI 2 v1 # Repeat Count - 1 NOP v2

Example - Repeats in the end only

NOP v1 IDXI 3 v2 NOP v1 IDXI 3 v2 NOP v1 IDXI 3 v2 NOP v1 IDXI 3 v2

STI 3 v1 # Loop Count -1 L: IDXI 3 v2 # Repeat Count of ending, ending vector as is JNI L v1 # Last iteration is not part of the loop IDXI 3 v2

Example - Repeats in the beginning and ending both

IDXI 3 v1 IDXI 4 v2 IDXI 3 v1 IDXI 4 v2 IDXI 3 v1 IDXI 4 v2 IDXI 3 v1 IDXI 4 v2 IDXI 3 v1 IDXI 4 v2

STI 3 v1 # Loop Count -1 L: IDXI 2 v1 # Repeat Count -1 of the beginning IDXI 4 v2 # Repeat Count of the ending, ending vector as is JNI L v1 IDXI 2 v1 # Repeat Count -1 of the beginning IDXI 4 v2 # Repeat Count of the ending, ending vector as is
