Bases: object

A helper class to get LLVM Values for integer C types.

numba_dpex.utils.llvm_codegen_helpers.create_null_ptr(builder, context)

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

Args:

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

numba_dpex.utils.llvm_codegen_helpers.get_llvm_ptr_type(type)

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

Args:

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

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

numba_dpex.utils.llvm_codegen_helpers.get_llvm_type(context, type)

Returns the LLVM Value corresponsing to a Numba type.

Args:

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.

numba_dpex.utils.llvm_codegen_helpers.get_one(context)

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

Args:

context: The LLVM IR builder context.

Returns: An LLVM Contant Value storing one.

numba_dpex.utils.llvm_codegen_helpers.get_zero(context)

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

Args:

context: The LLVM IR builder context.

Returns: An LLVM Contant Value storing zero.
