These instances will be compiled using a default -O3 option. The input code is first transformed into the Abstract Syntax Tree (AST) intermediate representation in GCCs front-end. This is where the machinelearning algorithm is integrated. The compiler enters the machine-learning routine before it traverses the A.S.T to generate the Register Transfer Language (RTL) representation. The machine-learning routine searches for the candidate program segments and records their positions in the compiled program. During the candidate program segment searching phase, the machine-learning |

Since such abstract interpretations are costly, and because the analyzed program is fixed for a given interpretation, it could be worthwhile to specialize (part of) the analysis for the given program. More pedantically, it may be interesting to par9 We view narrowing and widening operations as necessary heuristics to ensure that analysis terminate rather quickly, even when the analyzed program loops. . . Simple reflexive or introspective techniques could be useful here. 10 i.e., abstract interpretation based static analyzers 11 http://apron.cri.ensmp.fr/ with L.G.P.L license, wrapping |
