Code generator

Machine code generator.

The architecture is provided when the generator is created.

class ppci.codegen.codegen.CodeGenerator(arch, reporter, optimize_for='size')

Machine code generator

emit_frame_to_stream(frame, output_stream, debug=False)

Add code for the prologue and the epilogue. Add a label, the return instruction and the stack pointer adjustment for the frame. At this point we know how much stack space must be reserved for locals and what registers should be saved.

generate(ircode: ppci.ir.Module, output_stream, debug=False)

Generate machine code from ir-code into output stream

generate_function(ir_function, output_stream, debug=False)

Generate code for one function into a frame

generate_global(var, output_stream, debug)

Generate code for a global variable

select_and_schedule(ir_function, frame)

Perform instruction selection and scheduling
