* Add MO_AddIntC, MO_SubIntC MachOps and implement in X86 backendReid Barton2014-08-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Summary: These MachOps are used by addIntC# and subIntC#, which in turn are used in integer-gmp when adding or subtracting small Integers. The following benchmark shows a ~6% speedup after this commit on x86_64 (building GHC with BuildFlavour=perf). {-# LANGUAGE MagicHash #-} import GHC.Exts import Criterion.Main count :: Int -> Integer count (I# n#) = go n# 0 where go :: Int# -> Integer -> Integer go 0# acc = acc go n# acc = go (n# -# 1#) $! acc + 1 main = defaultMain [bgroup "count" [bench "100" $ whnf count 100]] Differential Revision: https://phabricator.haskell.org/D140
* Implement new CLZ and CTZ primops (re #9340)Herbert Valerio Riedel2014-08-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This implements the new primops clz#, clz32#, clz64#, ctz#, ctz32#, ctz64# which provide efficient implementations of the popular count-leading-zero and count-trailing-zero respectively (see testcase for a pure Haskell reference implementation). On x86, NCG as well as LLVM generates code based on the BSF/BSR instructions (which need extra logic to make the 0-case well-defined).

* remove SPARC related comment in PPC code generatorPeter Trommler2014-07-101-9/+0
| | | | | | | | | | | | | | | | Summary: PowerPC does not do delay slots and there is also no requirement to put extra instructions between FP operations and branches. Test Plan: None.

* Re-add more primops for atomic ops on byte arraysJohan Tibell2014-06-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | This is the second attempt to add this functionality. The first attempt was reverted in 950fcae46a82569e7cd1fba1637a23b419e00ecd, due to register allocator failure on x86. Given how the register allocator currently works, we don't have enough registers on x86 to support cmpxchg using complicated addressing modes. Instead we fall back to a simpler addressing mode on x86. Adds the following primops: * atomicReadIntArray# * atomicWriteIntArray# * fetchSubIntArray# * fetchOrIntArray# * fetchXorIntArray# * fetchAndIntArray# Makes these pre-existing out-of-line primops inline: * fetchAddIntArray# * casIntArray#
* Revert "Add more primops for atomic ops on byte arrays"Johan Tibell2014-06-261-4/+0
| | | | | | | | This commit caused the register allocator to fail on i386. This reverts commit d8abf85f8ca176854e9d5d0b12371c4bc402aac3 and 04dd7cb3423f1940242fdfe2ea2e3b8abd68a177 (the second being a fix to the first).

* Add LANGUAGE pragmas to compiler/ source filesHerbert Valerio Riedel2014-05-151-1/+1
| | | | | | | | | | | | | | | | | | In some cases, the layout of the LANGUAGE/OPTIONS_GHC lines has been reorganized, while following the convention, to - place `{-# LANGUAGE #-}` pragmas at the top of the source file, before any `{-# OPTIONS_GHC #-}`-lines. - Moreover, if the list of language extensions fit into a single `{-# LANGUAGE ... -#}`-line (shorter than 80 characters), keep it on one line. Otherwise split into `{-# LANGUAGE ... -#}`-lines for each individual language extension. In both cases, try to keep the enumeration alphabetically ordered. (The latter layout is preferable as it's more diff-friendly) While at it, this also replaces obsolete `{-# OPTIONS ... #-}` pragma occurences by `{-# OPTIONS_GHC ... #-}` pragmas.
* Add support for prefetch with locality levels.Austin Seipp2013-10-011-1/+4
| | | | | | | | | | | | | | | | | This patch adds support for several new primitive operations which support using processor-specific instructions to help guide data and cache locality decisions. We have levels ranging from [0..3] For LLVM, we generate llvm.prefetch intrinsics at the proper locality level (similar to GCC.) For x86 we generate prefetch{NTA, t2, t1, t0} instructions. On SPARC and PowerPC, the locality levels are ignored. This closes #8256. Authored-by: Carter Tazio Schonwald <carter.schonwald@gmail.com> Signed-off-by: Austin Seipp <austin@well-typed.com>

Patch from Vincent Hanquez.
* Refactor cmmMakeDynamicReferenceIan Lynagh2013-05-131-4/+4
| | | | | It now has its own class, and the addImport function is defined in that class, rather than needing to be passed as an argument.

* Remove OldCmm, convert backends to consume new CmmSimon Marlow2012-11-121-32/+40
| | | | | | | | | | | | | | | | | | This removes the OldCmm data type and the CmmCvt pass that converts new Cmm to OldCmm. The backends (NCGs, LLVM and C) have all been converted to consume new Cmm. The main difference between the two data types is that conditional branches in new Cmm have both true/false successors, whereas in OldCmm the false case was a fallthrough. To generate slightly better code we occasionally need to invert a conditional to ensure that the branch-not-taken becomes a fallthrough; this was previously done in CmmCvt, and it is now done in CmmContFlowOpt. We could go further and use the Hoopl Block representation for native code, which would mean that we could use Hoopl's postorderDfs and analyses for native code, but for now I've left it as is, using the old ListGraph representation for native code.
* Attach global register liveness info to Cmm procedures.Geoffrey Mainland2012-10-301-2/+2
| | | | | | | All Cmm procedures now include the set of global registers that are live on procedure entry, i.e., the global registers used to pass arguments to the procedure. Only global registers that are use to pass arguments are included in this list.
* Some alpha renamingIan Lynagh2012-10-161-2/+2
| | | | | Mostly d -> g (matching DynFlag -> GeneralFlag). Also renamed if* to when*, matching the Haskell if/when names
* Move wORD_SIZE into platformConstantsIan Lynagh2012-09-161-5/+6

* Pass DynFlags down to wordWidthIan Lynagh2012-09-121-5/+5
|
* Pass DynFlags down to bWordIan Lynagh2012-09-121-17/+20
| | | | | | 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.
* Handle II16 size value in PowerPC code generator.Erik de Castro Lopo2012-09-081-2/+2

* Move more code into codeGen/CodeGen/Platform.hsIan Lynagh2012-08-281-16/+19
| | | | | | | | 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.

* Make the PPC globalRegMaybe more similar to the other platforms'Ian Lynagh2012-08-211-1/+1
|
* Make -fPIC a dynamic flagIan Lynagh2012-07-161-9/+10
| | | | | | 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).
* Remove some more redundant Platform argumentsIan Lynagh2012-06-201-3/+2

* Remove lots of commented out 'in' keywordsIan Lynagh2012-06-131-5/+0
|
* Change how macros like ASSERT are definedIan Lynagh2012-06-051-0/+1
| | | | | 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 Lynagh2012-04-211-6/+7
| | | | | | | | It allows you to do (high, low) `quotRem` d provided high < d. Currently only has an inefficient fallback implementation.

* Add a 2-word-multiply operatorIan Lynagh2012-02-241-0/+1
| | | | Currently no NCGs support it
* Add a Word add-with-carry primopIan Lynagh2012-02-231-7/+6
| | | | No special-casing in any NCGs yet
* Add a primop for unsigned quotRem; part of #5598Ian Lynagh2012-02-171-0/+1
| | | | Only amd64 has an efficient implementation currently.
* Define a quotRem CallishMachOp; fixes #5598Ian Lynagh2012-02-141-4/+10
| | | | | 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).
* Track STG live register information for use in LLVMDavid Terei2012-01-091-1/+1
| | | | | | | | | 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.

* Get rid of the "safety" field of CmmCall (OldCmm)Simon Marlow2011-11-291-1/+1
| | | | | This field was doing nothing. I think it originally appeared in a very old incarnation of the new code generator.
* Fixes for NetBSDIan Lynagh2011-11-251-0/+1
| | | | | Based on a patch from Arnaud Degroote <degroote@NetBSD.org> in trac #5480.

* Revert "Remove OSUnknown"Ian Lynagh2011-10-191-0/+1
| | | | | | | This reverts commit f75f26cc4eed3c3cfc256ebfb9e77b8e82a766fc. On second thoughts, this does make sense, for unregisterised via-C OSes at least.
* Remove OSUnknownIan Lynagh2011-10-181-1/+0
| | | | | | It doesn't make sense. If platformOS is OSUnknown then we don't know the answer to any questions about the OS. So now if we don't recognise the OS we just fail, and the new OS will need to be added to the datatype.
* More CPP removal: pprDynamicLinkerAsmLabel in CLabelIan Lynagh2011-10-021-2/+3
