Program execution using interprocedural escape analysis with inlining

A system comprising

• a data repository storing a call graph of a target program;
• and
• a computer processor comprising instructions for a compiler to perform operations, the operations comprising:
• expanding the call graph of the target program to obtain an expanded call graph;
• performing, using the expanded call graph, an interprocedural escape analysis (IEA) to generate a materialization map;
• calculating an inlining benefit value for a callee using the materialization map;
• inlining, using the expanded call graph and in the target program, the callee according to the inlining benefit value;
• updating, after inlining the callee, an allocation in the target program;
• and
• completing, after updating the allocation, compilation of the target program.

A non-transitory computer readable program medium comprising instructions for causing a computer system to perform operations, the operations comprising:

• expanding a call graph of a target program to obtain an expanded call graph;
• performing, using the expanded call graph, an interprocedural escape analysis (IEA) to generate a materialization map;
• calculating an inlining benefit value for a callee using the materialization map;
• inlining, using the expanded call graph and in the target program, the callee according to the inlining benefit value;
• updating, after inlining the callee, an allocation in the target program;
• and
• completing, after updating the allocation, compilation of the target program.
