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.    *|
12|*                                                                            *|
13|* Note that these functions intentionally take liberties with the CAMLparamX *|
14|* macros, since most of the parameters are not GC heap objects.              *|
