Method and apparatus for compiler processing for a function marked with multiple execution spaces

摘要

A method for processing a function with a plurality of execution spaces is disclosed. The method comprises creating an internal compiler representation for the function. Creating the internal compiler representation comprises copying substantially all lexical tokens corresponding to a body of the function. Further, the creating comprises inserting the lexical tokens into a plurality of conditional if-statements, wherein a conditional if-statement is generated for each corresponding execution space of said plurality of execution spaces, and wherein each conditional if-statement determines which execution space the function is executing in. During compilation, the method finally comprises performing overload resolution at a call site of an overloaded function by checking for compatibility with a first execution space specified by one of the plurality of conditional if-statements, wherein the overloaded function is called within the body of the function.

1. A method for processing a function with a plurality of execution spaces comprising:
creating an internal compiler representation for said function, wherein said creating comprises:
copying substantially all lexical tokens corresponding to a body of said function; andinserting said lexical tokens into a plurality of conditional if-statements, wherein a conditional if-statement is generated for each corresponding execution space of said plurality of execution spaces, and wherein each conditional if-statement determines which execution space said function is executing in; and during compilation, performing overload resolution at a call site of an overloaded function by checking for compatibility with a first execution space specified by one of said plurality of conditional if-statements, wherein said overloaded function is called within said body of said function.
