Abstract: Processing instruction grouping information is provided that includes: reading addresses of machine instructions grouped by a processor at runtime from a buffer to form an address file; analyzing the address file to obtain grouping information of the machine instructions; converting the machine instructions in the address file into readable instructions; and obtaining grouping information of the readable instructions based on the grouping information of the machine instructions and the readable instructions resulted from conversion. Status of grouping and processing performed on instructions by a processor at runtime can be acquired dynamically, such that processing capability of the processor can be better utilized.

Abstract: A method for control flow analysis according to an embodiment of the present invention includes: acquiring an original function call tree of a program, wherein nodes of the original function call tree represent functions and a parent/child relation between the nodes represents a calling relation; generating a corresponding function dominator tree from the calling relation, wherein nodes of the function dominator tree represent the functions and a parent/child relation between the nodes represents a dominator relation, wherein a first function dominates a second function if all the invocations to the second function are originated by the first function; and simplifying the original function call tree according to the function dominator tree so as to obtain a simplified function call tree. According to an embodiment of the present invention, the function call tree for control flow analysis can be simplified.
