Abstract: A device compiler and linker within a parallel processing unit (PPU) is configured to optimize program code of a co-processor enabled application by rematerializing a subset of live-in variables for a particular block in a control flow graph generated for that program code. The device compiler and linker identifies the block of the control flow graph that has the greatest number of live-in variables, then selects a subset of the live-in variables associated with the identified block for which rematerializing confers the greatest estimated profitability. The profitability of rematerializing a given subset of live-in variables is determined based on the number of live-in variables reduced, the cost of rematerialization, and the potential risk of rematerialization.
