ABSTRACT:
A method for loop reformulation is provided such that a single exit ill-formed loop (SEIFL) can be reformulated into a reformulated code block that contains a transformed well-formed loop (TWFL). A SEIFL loop is a loop that can exit from the loop body of the loop. After the loop reformulation, the TWFL of the reformulated code block can only exit from the end of the loop. The reformulated code block will replace the SEIFL in the compiler's internal representation (IR) such that a more efficient executable machine code can be generated by optimizing the reformulated compiler's IR.
