Conversion operators try to generalise the from t0 x to t1
instructions from LLVM.
Constructors

The memory space of a block. If DefaultSpace, this is the "default"
space, whatever that is. The exact meaning of the SpaceID
depends on the backend used. In GPU kernels, for example, this is
used to distinguish between constant, global and shared memory
spaces. In GPU-enabled host code, it is used to distinguish
between host memory (DefaultSpace) and GPU space.
Constructors
| DefaultSpace | |
| Space SpaceId |
A primitive expression parametrised over the representation of
free variables. Note that the Functor, Traversable, and Num
instances perform automatic (but simple) constant folding.

constFoldPrimExp :: PrimExp v -> PrimExp v Source #

pattern Comment :: String -> Code a -> Code a Source #
Has the same semantics as the contained code, but the comment should show up in generated code for ease of inspection.
pattern Free :: VName -> Space -> Code a Source #
Indicate that some memory block will never again be referenced via the indicated variable. However, it may still be accessed through aliases. It is only safe to actually deallocate the memory block if this is the last reference. There is no guarantee that all memory blocks will be freed with this statement. Backends are free to ignore it entirely.
pattern Allocate :: VName -> Count Bytes -> Space -> Code a Source #
Memory space must match the corresponding
DeclareMem.
pattern Copy :: VName -> Count Bytes -> Space -> VName -> Count Bytes -> Space -> Count Bytes -> Code a Source #
Destination, offset in destination, destination space, source, offset in source, offset space, number of bytes.
pattern DeclareArray :: VName -> Space -> PrimType -> [PrimValue] -> Code a Source #
Create an array containing the given values. The lifetime of the array will be the entire application. This is mostly used for constant arrays, but also for some bookkeeping data, like the synchronisation counts used to implement reduction.
pattern DebugPrint :: String -> PrimType -> Exp -> Code a Source #
Print the given value (of the given type) to the screen, somehow annotated with the given string as a description. This has no semantic meaning, but is used entirely for debugging. Code generators are free to ignore this statement.
A imperative function, containing the body as well as its low-level inputs and outputs, as well as its high-level arguments and results. The latter are only used if the function is an entry point.
