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. *|
