Core API.

This interface provides an OCaml API for the LLVM intermediate representation, the classes in the VMCore library.

    type lltype

Each value in the LLVM IR has a type, an instance of `lltype`. See the `llvm::Type` class.

Iteration

    type ('a, 'b) llpos =

    type ('a, 'b) llrev_pos =

`|` | `At_start of `'a``
`|` | `After of `'b``

`After b` and `At_start a` specify positions from the end of the `'b` list of `a`. `llrev_pos` is used for reverse iteration through the various value lists maintained by the LLVM IR.

Exceptions

    exception FeatureDisabled of string

    exception IoError of string

Global configuration

    val enable_pretty_stacktrace : unit -> unit

`enable_pretty_stacktraces ()` enables LLVM's built-in stack trace code. This intercepts the OS's crash signals and prints which component of LLVM you were in at the time of the crash.

    val install_fatal_error_handler : (string -> unit) -> unit

`install_fatal_error_handler f` installs `f` as LLVM's fatal error handler. The handler will receive the reason for termination as a string. After the handler has been executed, LLVM calls `exit(1)`.

    val reset_fatal_error_handler : unit -> unit

`reset_fatal_error_handler ()` resets LLVM's fatal error handler.

    val parse_command_line_options : ?overview:string -> string array -> unit

`parse_command_line_options ?overview args` parses `args` using the LLVM command line parser. Note that the only stable thing about this function is its signature; you cannot rely on any particular set of command line arguments being interpreted the same way across LLVM versions.

See the function `llvm::cl::ParseCommandLineOptions()`.

Context error handling
