def miasm.ir.ir.IntermediateRepresentation.add_asmblock_to_ircfg	(		self,
			block,
			ircfg,
			gen_pc_updt = False
	)

Add a native block to the current IR
@block: native assembly block
@ircfg: IRCFG instance
@gen_pc_updt: insert PC update effects between instructions

Reimplemented in miasm.arch.mips32.ira.ir_a_mips32l, and miasm.arch.arm.sem.ir_arml.
