Lib.LinearCode module

CAP, CodeGeneration, LinearCode API Classes for a RiscV linear code.

class Lib.LinearCode.LinearCode(name: str)

Bases: object

Representation of a RiscV program as a list of instructions.

add_instruction() is repeatedly called in the codegen visitor to build a complete list of RiscV instructions for the source program.

The fdata member variable contains some meta-information on the program, for instance to allocate a new temporary. See Lib.FunctionData.FunctionData.

For debugging purposes, print_code() allows to print the RiscV program to a file.

fdata: FunctionData

add_instruction(i: Comment | Label | Instru3A | AbsoluteJump | ConditionalJump) → None

Utility function to add an instruction in the program.

See also Lib.RiscV to generate relevant instructions.

iter_statements(f) → None

Iterate over instructions. For each real instruction i (not label or comment), replace it with the list of instructions given by f(i).

get_instructions() → List[Comment | Label | Instru3A | AbsoluteJump | ConditionalJump]

Return the list of instructions of the program.

add_label(s: Label) → None

Add a label in the program.

add_comment(s: str) → None

Add a comment in the program.

add_instruction_PRINTLN_INT(reg: DataLocation) → None

Print integer value, with newline. (see Expand)

print_code(output, comment=None) → None

Outputs the RiscV program as text to a file at the given path.

print_dot(filename: str, DF=None, view=False) → None

Outputs the RiscV program as graph to a file at the given path.
