Detailed Description
Functions in this group relate to arguments/parameters on functions.
Functions in this group expect LLVMValueRef instances that correspond to llvm::Function instances.
Function Documentation
◆ LLVMCountParams()
| unsigned LLVMCountParams | ( | LLVMValueRef | Fn | ) |
Obtain the number of parameters in a function.
- See also
- llvm::Function::arg_size()
◆ LLVMGetFirstParam()
| LLVMValueRef LLVMGetFirstParam | ( | LLVMValueRef | Fn | ) |
Obtain the first parameter to a function.
- See also
- llvm::Function::arg_begin()
◆ LLVMGetLastParam()
| LLVMValueRef LLVMGetLastParam | ( | LLVMValueRef | Fn | ) |
Obtain the last parameter to a function.
- See also
- llvm::Function::arg_end()
◆ LLVMGetNextParam()
| LLVMValueRef LLVMGetNextParam | ( | LLVMValueRef | Arg | ) |
Obtain the next parameter to a function.
This takes an LLVMValueRef obtained from LLVMGetFirstParam() (which is actually a wrapped iterator) and obtains the next parameter from the underlying iterator.
◆ LLVMGetParam()
| LLVMValueRef LLVMGetParam | ( | LLVMValueRef | Fn, |
| unsigned | Index | ||
| ) |
Obtain the parameter at the specified index.
Parameters are indexed from 0.

- llvm::Function::arg_begin()
◆ LLVMGetParamParent()
| LLVMValueRef LLVMGetParamParent | ( | LLVMValueRef | Inst | ) |
Obtain the function to which this argument belongs.
Unlike other functions in this group, this one takes an LLVMValueRef that corresponds to a llvm::Attribute.
The returned LLVMValueRef is the llvm::Function to which this argument belongs.
◆ LLVMGetParams()
| void LLVMGetParams | ( | LLVMValueRef | Fn, |
| LLVMValueRef * | Params | ||
| ) |
Obtain the parameters in a function.
The takes a pointer to a pre-allocated array of LLVMValueRef that is at least LLVMCountParams() long. This array will be filled with LLVMValueRef instances which correspond to the parameters the function receives. Each LLVMValueRef corresponds to a llvm::Argument instance.

- llvm::Function::arg_begin()
◆ LLVMGetPreviousParam()
| LLVMValueRef LLVMGetPreviousParam | ( | LLVMValueRef | Arg | ) |
Obtain the previous parameter to a function.
This is the opposite of LLVMGetNextParam().
◆ LLVMSetParamAlignment()
| void LLVMSetParamAlignment | ( | LLVMValueRef | Arg, |
| unsigned | Align | ||
| ) |
Set the alignment for a function parameter.
