Abstract

The control flow of a first graphics-processing-unit shader program coded in a low-level programming language that allows arbitrary jumps is emulated in a second graphics-processing-unit shader program coded in a higher-level programming language that does not allow arbitrary jumps. Each instruction in the first program is individually evaluated as follows. First it is determined if the instruction is the first instruction in the first program or a jump destination therein. Whenever it is determined that the instruction is the first instruction in the first program or a jump destination therein, an appropriate case label is inserted into the second program. Then it is determined if the instruction is a jump instruction. Whenever it is determined that the instruction is a jump instruction, the jump instruction is translated into an appropriate switch case statement in the higher-level language, and this switch case statement is inserted into the second program.
