Function lookup_intrinsic_id

Source 
pub fn lookup_intrinsic_id(name: &str) -> Option<u32>
Expand description

Looks up the intrinsic ID number that matches the given function name within the module.

This function wraps the LLVMLookupIntrinsicID function from the LLVM core library. It searches for an intrinsic function within the LLVM module represented by m that matches the specified name. Intrinsic functions are special functions provided by LLVM that perform specific operations at a lower level.

§Parameters

  • m: The ModuleRef representing the LLVM module.
  • name: The name (&str) of the intrinsic function to look up.

§Returns

Returns an Option<u32> containing the intrinsic ID if a matching intrinsic is found, or None if no matching intrinsic exists within the module.
