arm

Arm machine specifics. The arm target has several options:

• thumb: enable thumb mode, emits thumb code

class ppci.arch.arm.ArmArch(options=None)

Arm machine class.

between_blocks(frame)

Generate any instructions here if needed between two blocks

determine_arg_locations(arg_types)

Given a set of argument types, determine location for argument ABI: pass arg1 in R1 pass arg2 in R2 pass arg3 in R3 pass arg4 in R4 return value in R0

determine_rv_location(ret_type)

Determine the location of a return value of a function given the type of return value

gen_call(frame, label, args, rv)

Generate instructions for a function call.

gen_epilogue(frame)

Return epilogue sequence for a frame.

Adjust frame pointer and add constant pool.

Also free up space on stack for:

• Space for parameters passed to called functions.
• Space for save registers
• Space for local variables

gen_function_enter(args)

Generate code to extract arguments from the proper locations

The default implementation tries to use registers and move instructions.

Parameters:args – an iterable of virtual registers in which the arguments must be placed.

gen_prologue(frame)

Returns prologue instruction sequence.

Reserve stack for this calling frame for:

• local variables
• save registers
• parameters to called functions

get_runtime()

Implement compiler runtime functions

litpool(frame)

Generate instruction for the current literals

move(dst, src)

Generate a move from src to dst
