Structure _If_ Statement

You have a conditional jump over consecutive statements.
Negate the conditional expression and make statements the conditional clause.

        if(cond)
                goto skip;
        /* cond is false */
        ...
skip:

⇓

        if(!cond) {
                /* cond is false */
                ...
        }

Motivation

If-then statements are translated by the compiler as a conditional jump over the statements that constitute the then clause. This refactoring recovers the original control structure.

Mechanics

Negative the if statement condition.
Replace the jump by the skipped statements.
Remove the jump label, if not longer used.
