    • A compile converts a program having a multiple execution paths so as to expand a basic block on a specific execution path while maintaining the program integrity. The complier generates new basic blocks B103 and B104. The basic block B104 is composed of (i) statements generated by replacing replacement target variables in a partial source program (basic blocks B1-B7) on a hot path 200, and (ii) a branch instruction that includes a branch condition for executing the hot path, generated by modifying a branch instruction on the hot path 200. The basic block B103 is composed of statements for restoring restoration target variables out of the replacement target variables. The source program is then converted to execute, subsequently to the basic block B104, the basic block B103 if the branch instruction in the basic block B103 is true, and to execute the basic block B1 if false.
    • 编译转换具有多个执行路径的程序,以便在保持程序完整性的同时扩展特定执行路径上的基本块。 编译器生成新的基本块B 103和B 104。 基本块B104由(i)通过在热路径200上替换部分源程序(基本块B 1 -B 7)中的替换目标变量而生成的语句,以及(ii)包括分支条件的分支指令 用于执行通过修改热路径200上的分支指令而生成的热路径。 基本块B103由用于从替换目标变量恢复恢复目标变量的语句组成。 然后,如果基本块B 103中的分支指令为真,则源程序随后被转换为执行基本块B 104,基本块B 103,并且如果为假则执行基本块B1。
