摘要： A technique for comprehensively acquiring calling-context information at a low cost. Call site IDs are held for each thread as a call history and used as context information. At the time of calling a method, the call history existing in a current frame is shifted left, and stacked in a new frame, with the call site ID of the call site put in the lower bits. At the time of returning from the method, the value of the original call history is returned by returning the frame. At the time of performing a virtual call, call history information is recorded into a call position profile table used to identify a method to be inlined at the time of performing JIT compiling, in addition to determined jump destination information and the number of calls.

摘要： A method and system for code generation and inlining. The method includes: scanning a code, where the code includes a method; determining whether the method includes a branch if the method is too large in size to be inlined, where the branch is based on runtime types of argument; profiling runtime types of actual arguments at a call site in the method if the method includes the branch; generating a polymorphic inline cache (PIC) code from a plurality of arguments, where the plurality of arguments are based on a result of the profiling step; generating a specialized method for a frequently appearing combination of the runtime types of argument and arguments that can be invoked from the PIC code; and inlining body of the specialized method into the call site if the specialized method has a body size within a permissible range.

摘要： A method, computer program product and system for improving performance of a program during runtime. The method includes reading source code; generating a dependence graph with a dependency for (1) data or (2) side effects; generating a postdominator tree based on the dependence graph; identifying a portion of the program able to be delayed using the postdominator tree; generating delay closure code; profiling a location where the location is where the delay closure code is forced; inlining the delay closure code into a frequent location in which the delay closure code has been forced with high frequency; partially evaluating the program; and generating fast code which eliminates an intermediate data structure within the program, where at least one of the steps is carried out using a computer device so that performance of the program during runtime is improved.
