Halide::LinkageType::Internal
@ Internal
Not visible externally, similar to 'static' linkage in C.
Halide::Internal::get_initial_module_for_ptx_device
std::unique_ptr< llvm::Module > get_initial_module_for_ptx_device(Target, llvm::LLVMContext *c)
Create an llvm module containing the support code for ptx device.
Halide::Internal::get_initial_module_for_target
std::unique_ptr< llvm::Module > get_initial_module_for_target(Target, llvm::LLVMContext *, bool for_shared_jit_runtime=false, bool just_gpu=false)
Create an llvm module containing the support code for a given target.
