Buffer of assembly code

val emit : X86_ast.instruction -> unit
val directive : X86_ast.asm_line -> unit
val reset_asm_code : unit -> unit

Code emission

val generate_code : (X86_ast.asm_line list -> unit) option -> unit

Post-process the stream of instructions. Dump it (using the provided syntax emitter) in a file (if provided) and compile it with an internal assembler (if registered through register_internal_assembler).

val assemble_file : string -> string -> int

Generate an object file corresponding to the last call to generate_code. An internal assembler is used if available (and the input file is ignored). Otherwise, the source asm file with an external assembler.
