* Move more code into codeGen/CodeGen/Platform.hsIan Lynagh2012-08-288-15/+39
| | | | | | | | HaskellMachRegs.h is no longer included in anything under compiler/ Also, includes/CodeGen.Platform.hs now includes "stg/MachRegs.h" rather than <stg/MachRegs.h> which means that we always get the file from the tree, rather than from the bootstrapping compiler.

* Fix the generation of CallerSaves; fixes #7163Ian Lynagh2012-08-2111-53/+97
| | | | | | | | | Simon Marlow spotted that we were #include'ing MachRegs.h several times, but that doesn't work as (a) it uses ifdeffery to avoid being included multiple times, and (b) even if we work around that, then the #define's from previous inclusions are still defined when we #include it again. So we now put the platform code for each platform in a separate .hs file.

|
* entryHeapCheck: fix calls to stg_gc_fun and stg_gc_enter_1Simon Marlow2012-08-072-23/+28
| | | | | | | | | We weren't passing the arguments correctly to the GC functions, which usually happened to work because the arguments were in the right registers already. After this fix the profiling tests go through with the new code generator.
* Small optimisationSimon Marlow2012-08-071-5/+6
| | | | | | When calling newCAF, refer to the closure using its LocalReg rather than R1. Using R1 here was preventing the register allocator from coalescing the assignment x=R1 at the beginning of the function.
* fix a warningSimon Marlow2012-08-071-1/+1

* A closure with void args only should be a function, not a thunkSimon Marlow2012-08-071-4/+3
|
* Generate one fewer temps per heap allocationSimon Marlow2012-08-074-40/+28
| | | | | This saves compile time and can make a big difference in some pathological cases (T4801)
* Define callerSaves for all platformsIan Lynagh2012-08-075-179/+76
| | | | | | | | This means that we now generate the same code whatever platform we are on, which should help avoid changes on one platform breaking the build on another. It's also another step towards full cross-compilation.
* Add "Unregisterised" as a field in the settings fileIan Lynagh2012-08-0710-67/+91
| | | | | | To explicitly choose whether you want an unregisterised build you now need to use the "--enable-unregisterised"/"--disable-unregisterised" configure flags.
* Make tablesNextToCode "dynamic"Ian Lynagh2012-08-069-85/+90
| | | | | This is a bit odd by itself, but it's a stepping stone on the way to putting "target unregisterised" into the settings file.
* Start separating out the RTS and Haskell imports of MachRegs.hIan Lynagh2012-08-062-2/+2
| | | | No functional differences yet
* Use "ReturnedTo" when generating safe foreign callsSimon Marlow2012-08-064-34/+33

* Add a comment to explain why the FCode monad is lazySimon Marlow2012-08-062-1/+9
|
* Explicitly share some return continuationsSimon Marlow2012-08-029-163/+252
| | | | | | | Instead of relying on common-block-elimination to share return continuations in the common case (case-alternative heap checks) we do it explicitly. This isn't hard to do, is more robust, and saves some compilation time. Full commentary in Note [sharing continuations].
* Small optimisation to the code generated for CAFsSimon Marlow2012-07-302-16/+33
|
* New codegen: do not split proc-points when using the NCGSimon Marlow2012-07-306-15/+26
| | | | | | | | | Proc-point splitting is only required by backends that do not support having proc-points within a code block (that is, everything except the native backend, i.e. LLVM and C). Not doing proc-point splitting saves some compilation time, and might produce slightly better code in some cases.
* Make -fscc-profiling a dynamic flagIan Lynagh2012-07-2427-504/+610
| | | | All the flags that 'ways' imply are now dynamic
* Small code simplificationIan Lynagh2012-07-181-4/+2

* Whitespace only in CgHeaperyIan Lynagh2012-07-171-249/+242
|
* Make -fPIC a dynamic flagIan Lynagh2012-07-162-17/+18
| | | | | | Hopefully I've kept the logic the same, and we now generate warnings if the user does -fno-PIC but we ignore them (e.g. because they're on OS X amd64).
* 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.

* remove some redundant SRT-related stuffSimon Marlow2012-07-116-38/+18
|
* 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.
