Abstract
A method for a compiler includes receiving, by the compiler and from an interpreter, a representation of a code section having a control path that changes the representation. The representation has profiling data, and the profiling data has a threshold. The method further includes performing, by the compiler and based on the threshold, a partial evaluation of the interpreter executing the representation, compiling, by the compiler, a machine code of the representation, with the control path replaced by a deoptimization point during the compilation of the machine code, triggering the deoptimization point during execution of the machine code, and returning execution to the interpreter based on the triggering.
