dot.llvm: Invoke an LLVM Function from R
In doktorschiwago/Rllvm2: Interface to llvm for dynamically compiling native code.

Description Usage Arguments Value Author(s) References See Also Examples

These functions provide the mechanism to call an LLVM Function, passing it R objects as arguments. This is analogous to the .C interface, but for routines generated via LLVM, either read from existing files or generated in the R session.

.llvm(.x, ..., .args = list(...),
      .ee = ExecutionEngine(as(.x, "Module")),
      .all = FALSE, .duplicate = .duplicateArgs(.x))

`.x`	the reference to the LLVM `Function` object
`...`	arguments for the `Function`
`.args`	an alternative way mechanism to pass the arguments for the `Function` as a single R list.
`.ee`	the LLVM `ExecutionEngine` providing the context for the `Function`. This can be created for each call or an instance can be reused across calls.
`.all`	a logical value that controls whether all of the arguments are also returned, or just the return value from the `Function` is returned. When the `Function` can modify any of the arguments `.all = TRUE` is typically important.
`.duplicate`	a logical vector indicating which arguments need to be copied before being passed to the `Function`. This allows us to avoid copying inputs which are not mutated/modified by the `Function`.
