| IRFunction (const std::string &symbol, const GeneratorCb &gen) |
|
llvm::Type * | types (std::vector< llvm::Type * > &types, llvm::LLVMContext &C) const override |
| Populate a vector of llvm::Types which describe this function signature. This method is used by Function::create, Function::print and Function::match.
|
|
void | setEmbedIR (bool on) |
| Enable or disable the embedding of IR. Embedded IR is currently required for function which use parent function parameters.
|
|
bool | hasEmbedIR () const |
|
llvm::Function * | create (llvm::LLVMContext &C, llvm::Module *M) const override |
| Override for the creation of an IR function. This ensures that the body and prototype of the function are generated if a Module is provided.
|
|
llvm::Function * | create (llvm::Module &M) const |
| Convenience method which always uses the provided module to find the function or insert it if necessary.
|
|
llvm::Value * | call (const std::vector< llvm::Value * > &args, llvm::IRBuilder<> &B, const bool cast) const override |
| Override for call, which is only necessary if mEmbedIR is true, as the IR generation for embedded functions is delayed until the function is called. If mEmbedIR is false, this simply calls Function::call.
|
|
llvm::Function * | get (const llvm::Module &M) const |
| Convenience method for calling M.getFunction(symbol). Returns a nullptr if the function has not yet been created or if it is embedded IR.
|
|
virtual SignatureMatch | match (const std::vector< llvm::Type * > &inputs, llvm::LLVMContext &C) const |
| The base implementation for determining how a vector of llvm arguments translates to this functions signature. Returns an enum which represents the available mapping.
|
|
size_t | size () const |
| The number of arguments that this function has.
|
|
const char * | symbol () const |
| The function symbol name.
|
|
const char * | argName (const size_t idx) const |
| Returns the descriptive name of the given argument index.
|
|
virtual void | print (llvm::LLVMContext &C, std::ostream &os, const char *name=nullptr, const bool axTypes=true) const |
| Print this function's signature to the provided ostream.

The base implementation for determining how a vector of llvm arguments translates to this functions signature. Returns an enum which represents the available mapping.
This method calls types() to figure out the function signature, then compares each argument type to the type in the input vector. If the types match exactly, an Explicit match is found. If the sizes of the inputs and signature differ, no match is found and None is returned. If however, the sizes match and there exists a valid implicit cast from the input type to the signature type for every input, an Implicit match is returned. Finally, if the sizes match but there is no implicit cast mapping, Size is returned. i8 -> i32 : Implicit i32 -> i32 : Explicit str -> i32 : Size (i32,i32) -> i32 : None
- Note
- Due to the way CFunctionSRet is implemented, the LLVM Context must be provided in case we have a zero arg function signature with a SRET.
