CSR address width.

extensions:

All supported extensions in the form of a bitwise or of Extension.

__init__(isa_str: str)
Parameters
isa_strstr

String identifying a specific RISC-V ISA. Please refer to GCC’s machine-dependent arch option for details.

coreblocks.arch.optypes module

class coreblocks.arch.optypes.CfiType

Bases: IntEnum

Types of control flow instructions.

There are 4 main types: invalid, branch, JAL, and JALR. CALL and RET are just special cases of respectively JAL and JALR and thus the encoding was chosen in the way that it is sufficient to check the lowest two bits to get the main type and the third bit is just a hint about the specialized type.

Because of these encoding tweaks, helper functions should be preferred to use to get the CFI type.
