* Implement FastBytes, and use it for MachStrIan Lynagh2012-07-142-3/+2
| | | | | | | | | | | | | This is a first step on the way to refactoring the FastString type. FastBytes currently has no unique, mainly because there isn't currently a nice way to produce them in Binary. Also, we don't currently do the "Dictionary" thing with FastBytes in Binary. I'm not sure whether this is important. We can change both decisions later, but in the meantime this gets the refactoring underway.

* Track liveness of GlobalRegs in the new code generatorSimon Marlow2012-07-092-21/+24
| | | | | | This gives the register allocator access to R1.., F1.., D1.. etc. for the new code generator, and is a cheap way to eliminate all the extra "x = R1" assignments that we get from copyIn.

| | | | | | | | | | 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
| | * Remove StgTypeArg since it was never used and is probably broken anywayMax Bolingbroke2012-05-152-7/+3
| | |
| * | 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 setByteArray# primopIan Lynagh2012-05-282-2/+30

| * 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.

| | | | | | | | | | | | Only amd64 has an efficient implementation currently.
| | * 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"

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we support only numeric literals but---hopefully---these modifications should make it fairly easy to add other ones, if necessary.
* | | | | | Improve the case-alternative heap checksSimon Marlow2012-03-072-32/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code we were generating for heap-checks in algebraic case alternatives wasn't working well with the common-block eliminator. A small tweak to make the heap-check failure jump back to the same place in all branches lets the common-block eliminator squash more code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We also generate much better code for safe foreign calls (and maybe also unsafe foreign calls) than previously. See the two new Notes: Note [lower safe foreign calls] Note [safe foreign call convention]
