Functions

declare_function(context, builder, name, sig, cargs, mangler=mangle_c)

Insert declaration for a opencl builtin function. Uses the Itanium mangler.

Parameters:

• context (target context)

• builder (llvm builder)

• name (str) – symbol name

• sig (signature) – function signature of the symbol being declared

• cargs (sequence of str) – C type names for the arguments

• mangler (a mangler function) – function to use to mangle the symbol

get_llvm_type(context, type)

Returns the LLVM Value corresponding to a Numba type.

Parameters:

• context – The LLVM context or the execution state of the current IR

• generator.

• type – A Numba type object.

Returns: An Python object wrapping an LLVM Value corresponding to the

specified Numba type.

get_llvm_ptr_type(type)

Returns an LLVM pointer type for a give LLVM type object.

Parameters:

type – An LLVM type for which we need the corresponding pointer type.

Returns: An LLVM pointer type object corresponding to the input LLVM type.

create_null_ptr(builder, context)

Allocates a new LLVM Value storing a void* and returns the Value to caller.

Parameters:

• builder – The LLVM IR builder to be used for code generation.

• context – The LLVM IR builder context.

Returns: An LLVM value storing a null pointer

get_zero(context)

Returns an LLVM Constant storing a 64 bit representation for zero.

Parameters:

context – The LLVM IR builder context.

Returns: An LLVM Constant Value storing zero.

get_one(context)

Returns an LLVM Constant storing a 64 bit representation for one.

Parameters:

context – The LLVM IR builder context.

Returns: An LLVM Constant Value storing one.
