Compiling method with exception handling

A computer comprising:

• a compiler program, for compiling source code for a target program and converting said source code into machine language code;
• and
• a processor, for executing said machine language code for said target program,
• wherein said compiler includes
• a lock data generator for, based on inlining data for a function in said target program, generating lock data for a resource by using said obtained inlined function, and
• a data addition unit for employing said lock data to add, to said target program, data concerning a lock count upon the execution of code for said target program, and
• wherein, when an exception has occurred during the execution of said target program, based on said data concerning said lock count, said processor obtains a lock count upon the execution of code wherein said exception occurred and a lock count upon the execution of an exception handler, and performs a process for said exception after the locks of said resource are released in a number equivalent to the difference between those two lock counts.

A program storage device readable by a computing machine, tangibly embodying a compiler program of instructions executable by the machine to perform method steps of a compiling method for converting, into machine language, source code for a target program prepared using a programming language, said method comprising the steps of:

• (a) performing the inlining of a function in said target program and generating information concerning said inlining by an inlining unit of said compiler program;
• (b) generating, based on said information concerning said inlining, lock data concerning a lock set for a resource using said function by a lock data generator of said compiler program;
• and
• (c) adding, based on said lock data, a lock count set upon the execution of an exception handler in said target program by a data addition unit of said compiler program.
