> The IPA pass for function recompile, marks any function with loops for
> recompile once, even in cases where not a single statement block is marked
> for recompilation. Here is an example:
> {code}
> ---FUNCTION .defaultNS::foo [recompile=true]
> ------GENERIC (lines 24-24) [recompile=false]
> --------CP assignvar input.SCALAR.INT.false out.SCALAR.INT
> ------FOR (lines 0-0)
> --------CP assignvar 1.SCALAR.INT.true __pred.SCALAR.INT
> --------CP assignvar 2.SCALAR.INT.true __pred.SCALAR.INT
> --------CP assignvar 1.SCALAR.INT.true __pred.SCALAR.INT
> --------GENERIC (lines 26-27) [recompile=false]
> ----------CP uak+ X.MATRIX.DOUBLE _Var57.SCALAR.DOUBLE 8
> ----------CP castvti _Var57.SCALAR.DOUBLE.false _Var58.SCALAR.INT
> ----------CP rmvar _Var57
> ----------CP + input.SCALAR.INT.false _Var58.SCALAR.INT.false
> _Var59.SCALAR.INT
> ----------CP rmvar _Var58
> ----------CP mvvar _Var59 out
> {code}
