Core API.
This interface provides an OCaml API for the LLVM intermediate representation, the classes in the VMCore library.
Abstract types
These abstract types correlate directly to the LLVMCore classes.

. See the llvm::Value

Iteration
Before b
and At_end a
specify positions from the start of the 'b
list of a
. llpos
is used to specify positions in and for forward iteration through the various value lists maintained by the LLVM IR.
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
Global configuration
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.
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)
.
reset_fatal_error_handler ()
resets LLVM's fatal error handler.
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.
