| | * Fix generic 2-word-multiplyIan Lynagh2012-02-241-3/+3

| | * Add a 2-word-multiply operatorIan Lynagh2012-02-241-0/+48
| | | | | | | | | | | | Currently no NCGs support it
| | * Add a Word add-with-carry primopIan Lynagh2012-02-232-8/+58
| | | | | | | | | | | | No special-casing in any NCGs yet
| | * Add a primop for unsigned quotRem; part of #5598Ian Lynagh2012-02-171-0/+8
| | | | | | | | | | | | 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 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.

* | | | Fix an SRT-related bugSimon Marlow2012-02-146-73/+48
|/ / / | | | | | | | | | | | | | | | | | | | | | We were using the SRT information generated by the computeSRTs pass to decide whether to add a static link field to a constructor or not, and this broke when I disabled computeSRTs for the new code generator. So I've hacked it for now to only rely on the SRT information generated by CoreToStg.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also: - improvements to code generation: push slow-call continuations on the stack instead of generating explicit continuations - remove unused CmmInfo wrapper type (replace with CmmInfoTable) - squash Area and AreaId together, remove now-unused RegSlot - comment out old unused stack-allocation code that no longer compiles after removal of RegSlot

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is so that we can process the Stg code in constant space. Before we were generating all the C-- up front, leading to a large space leak. I haven't converted the LLVM or C back ends to the incremental scheme, but it's not hard to do.

| * 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.

| * More changes aimed at improving call stacks.Simon Marlow2011-12-022-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Attach a SrcSpan to every CostCentre. This had the side effect that CostCentres that used to be merged because they had the same name are now considered distinct; so I had to add a Unique to CostCentre to give them distinct object-code symbols. - New flag: -fprof-auto-calls. This flag adds an automatic SCC to every call site (application, to be precise). This is typically more useful for call stacks than annotating whole functions. Various tidy-ups at the same time: removed unused NoCostCentre constructor, and refactored a bit in Coverage.lhs. The call stack we get from traceStack now looks like this: Stack trace: Main.CAF (<entire-module>) Main.main.xs (callstack002.hs:18:12-24) Main.map (callstack002.hs:13:12-16) Main.map.go (callstack002.hs:15:21-34) Main.map.go (callstack002.hs:15:21-23) Main.f (callstack002.hs:10:7-43)
* | Move includes/DerivedConstants.h and includes/GHCConstants.h into dist dirsIan Lynagh2011-12-024-4/+4
|/ | | | | | | | | | When they existed, they were getting included in the includes_H_FILES variable (as it uses wildcard to find all header files). But the .depends files for the programs that generate the headers depend on $(includes_H_FILES), so the .depends files looked out-of-date once the headers had been created. This caused unnecessary make reinvocations. So now we put them in dist* directories, where they ought to be anyway.
