* Partially fix #367 by adding HpLim checks to entry with -fno-omit-yields.Edward Z. Yang2012-09-262-23/+38
| | | | | | | | | | | | | | | | | | | | | The current fix is relatively dumb as far as where to add HpLim checks: it will always perform a check unless we know that we're returning from a closure or we are doing a non let-no-escape case analysis. The performance impact on the nofib suite looks like this: Min +5.7% -0.0% -6.5% -6.4% -50.0% Max +6.3% +5.8% +5.0% +5.5% +0.8% Geometric Mean +6.2% +0.1% +0.5% +0.5% -0.8% Overall, the executable bloat is the biggest problem, so we keep the old omit-yields optimization on by default. Remember that if you need an interruptibility guarantee, you need to recompile all of your libraries with -fno-omit-yields. A better fix would involve only inserting the yields necessary to break loops; this is left as future work. Signed-off-by: Edward Z. Yang <ezyang@mit.edu>

* Make StgWord a portable type tooIan Lynagh2012-09-188-40/+38
| | | | | StgWord is a newtyped Word64, as it needed to be something that has a UArray instance.
* Make StgHalfWord a portable typeIan Lynagh2012-09-186-56/+60
| | | | | It's now a newtyped Integer. Perhaps a newtyped Word32 would make more sense, though.

|
* Move wORD_SIZE_IN_BITS to DynFlagsIan Lynagh2012-09-142-4/+4
| | | | This frees wORD_SIZE up to be moved out of HaskellConstants

|
* Pass DynFlags down to bWordIan Lynagh2012-09-1230-939/+993
| | | | | | I've switched to passing DynFlags rather than Platform, as (a) it's simpler to not have to extract targetPlatform in so many places, and (b) it may be useful to have DynFlags around in future.

|
* Fix -split-objs with the new code generatorSimon Marlow2012-09-043-28/+6
| | | | | | We need to make the SRT label external and unique when splitting, because it is shared amongst all the functions in the module. Also some SRT-related cleanup.
* Narrow the args of the popCnt# primitives (new codegen)Simon Marlow2012-09-041-5/+10
| | | | (this change was previously done in the old codegen only)

|
* Remove doingTickyProfilingIan Lynagh2012-09-034-6/+6
| | | | It's now just 'dopt Opt_Ticky'
* Narrow the arg of popCnt# to the correct widthSimon Marlow2012-08-311-6/+15
| | | | | | | Fixes cgrun071 on recent Mac OS X versions. This is the right fix at least until we have proper types for Word8#, Word16# etc.
* Cleanup: add mkIntExpr and zeroExpr utilsSimon Marlow2012-08-3112-54/+53

* 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 callerSaves, activeStgRegs, haveRegBase when unregisterisedSimon Marlow2012-08-281-0/+6

* StgCmmUtils no longer needs to include HaskellMachRegs.hIan Lynagh2012-08-211-1/+0

|
* 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.
