  10 |* This file glues LLVM's OCaml interface to its C interface. These functions *|
  11 |* are by and large transparent wrappers to the corresponding C functions.    *|

  13 |* Note that these functions intentionally take liberties with the CAMLparamX *|
  14 |* macros, since most of the parameters are not GC heap objects.              *|
