The instruction selection phase takes care of scheduling and instruction selection. The output of this phase is a one frame per function with a flat list of abstract machine instructions. To select instruction, a tree rewrite system is used. This is also called bottom up rewrite generator (BURG).

NettetInstruction selection In the Instruction selection, the design issues in the code generator program's efficiency will be improved by selecting the optimum instructions. It contains all of the instructions, which should be thorough and consistent. Regarding efficiency, instruction speeds and machine idioms have a big effect. NettetThis DAG is constructed as the first step of instruction selection in order to allow implementation of machine specific optimizations and code simplifications. The representation used by the SelectionDAG is a target-independent representation, which has some similarities to the GCC RTL representation, but is significantly more simple, …
