Abstract
A method and apparatus for transforming JAVA Native Interface function calls to constants, internal just-in-time (JIT) compiler operations or simpler intermediate representation. A compiler generates a plurality of intermediate representations for a plurality of native interface function calls. During inlining of native code, matching is performed on each native function call (against this list) and a list of native interface function calls is generated. For each native interface function call, a (JIT) call transformer attempts to replace the native interface function call with a constant, internal JIT compiler operation or a simpler intermediate representation depending on the type of native interface function call.
