Definition of a machine model (architecture + compiler).

  • since 30.0-Zinc
val mach_to_yaml : mach -> Yaml.value
val mach_of_yaml : Yaml.value -> (mach, [> `Msg of string ]) result

Compiler

val msvcMode : mach -> bool

Short for machdep.compiler = "msvc"

  • since 30.0-Zinc
val gccMode : mach -> bool

Short for machdep.compiler = "gcc"

  • since 30.0-Zinc
val allowed_machdep : string -> string

allowed_machdep "machdep family" provides a standard message for features only allowed for a particular machdep.

  • since 30.0-Zinc

Generation

val gen_all_defines : Format.formatter -> ?censored_macros:Datatype.String.Set.t -> mach -> unit

Prints on the given formatter all #define directives required by share/libc/features.h and other system-dependent headers.

  • parameter censored_macros

    prevents the generation of directives for the builtin macros in mach.custom_defs whose names match. empty by default.

  • before 29.0-Copper

    censored_macros did not exist

val generate_machdep_header : ?censored_macros:Datatype.String.Set.t -> mach -> Filepath.Normalized.t

generates a __fc_machdep.h file in a temp directory and returns the directory name, to be added to the search path for preprocessing stdlib.

  • before 29.0-Copper

    censored_macros did not exist.
