A method for partitioning programs into multi-procedure modules for efficient compilation. During interprocedural analysis, a weighted callgraph of the program is constructed in which weights on nodes represent code size of each procedure and weights on edges between the nodes represent execution counts between procedures. A coloured interference graph is built from the analysis information, and is used to induce weighted sub-graphs of the callgraph containing no interferences between procedures in each sub-graph. The procedures from a single sub-graph are combined into one or more modules; procedures with the highest weighted edges between them are combined in a module first until the cumulative node weight of the module reaches a preset limit on memory size.
