| | | | | We can now get the Platform from the DynFlags inside an SDoc, so we no longer need to pass the Platform in.

* Fix for earger blackholing of thunks with no free variables (#6146)Simon Marlow2012-06-074-12/+16
| | | | | | | | | | | | | | | | | A thunk with no free variables was not getting blackholed when -feager-blackholing was on, but we were nevertheless pushing the stg_bh_upd_frame version of the update frame that expects to see a black hole. I fixed this twice for good measure: - we now call blackHoleOnEntry when pushing the update frame to check whether the closure was actually blackholed, and so that we use the same predicate in both places - we now black hole thunks even if they have no free variables. These only occur when optimisation is off, but presumably if you say -feager-blackholing then that's what you want to happen.

| * Support code generation for unboxed-tuple function argumentsunboxed-tuple-arguments2Max Bolingbroke2012-05-1512-47/+61
| | | | | | | | | | | | | | | | | | | | | | This is done by a 'unarisation' pre-pass at the STG level which translates away all (live) binders binding something of unboxed tuple type. This has the following knock-on effects: * The subkind hierarchy is vastly simplified (no UbxTupleKind or ArgKind) * Various relaxed type checks in typechecker, 'foreign import prim' etc * All case binders may be live at the Core level

* | Change how macros like ASSERT are definedIan Lynagh2012-06-059-1/+9
| | | | | | | | | | By using Haskell's debugIsOn rather than CPP's "#ifdef DEBUG", we don't need to kludge things to keep the warning checker happy etc.

* Add a quotRemWord2 primopIan Lynagh2012-04-211-0/+53
| | | | | | | | It allows you to do (high, low) `quotRem` d provided high < d. Currently only has an inefficient fallback implementation.

| * Implement "value" imports with the CAPIIan Lynagh2012-02-262-2/+6
| | | | | | | | | | | | This allows us to import values (i.e. non-functions) with the CAPI. This means we can access values even if (on some or all platforms) they are simple #defines.

| * Define a quotRem CallishMachOp; fixes #5598Ian Lynagh2012-02-141-0/+9
| | | | | | | | | | This means we no longer do a division twice when we are using quotRem (on platforms on which the op is supported; currently only amd64).
* | Add support for type-level "strings".Iavor S. Diatchki2012-01-242-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | These are types that look like "this" and "that". They are of kind `Symbol`, defined in module `GHC.TypeLits`. For each type-level symbol `X`, we have a singleton type, `TSymbol X`. The value of the singleton type can be named with the overloaded constant `tSymbol`. Here is an example: tSymbol :: TSymbol "Hello"

| | | | | | | | | | | | | | | | | | We now carry around with CmmJump statements a list of the STG registers that are live at that jump site. This is used by the LLVM backend so it can avoid unnesecarily passing around dead registers, improving perfromance. This gives us the framework to finally fix trac #4308.

| * Add new primtypes 'ArrayArray#' and 'MutableArrayArray#'Manuel M T Chakravarty2011-12-072-4/+34
| | | | | | | | | | | | | | | | The primitive array types, such as 'ByteArray#', have kind #, but are represented by pointers. They are boxed, but unpointed types (i.e., they cannot be 'undefined'). The two categories of array types —[Mutable]Array# and [Mutable]ByteArray#— are containers for unboxed (and unpointed) as well as for boxed and pointed types. So far, we lacked support for containers for boxed, unpointed types (i.e., containers for the primitive arrays themselves). This is what the new primtypes provide. Containers for boxed, unpointed types are crucial for the efficient implementation of scattered nested arrays, which are central to the new DPH backend library dph-lifted-vseg. Without such containers, we cannot eliminate all unboxing from the inner loops of traversals processing scattered nested arrays.
