* Add x86 implementations of the quotRem, Mul2 and Add2 primopsIan Lynagh2012-02-241-2/+59
|
* Implement 2-word-multiply for x86_64Ian Lynagh2012-02-243-0/+19
|
* Add a 2-word-multiply operatorIan Lynagh2012-02-243-0/+3
| | | | Currently no NCGs support it
* Add x86_64 support for the add-with-carry opIan Lynagh2012-02-231-0/+13
|
* Add a Word add-with-carry primopIan Lynagh2012-02-233-33/+29
| | | | No special-casing in any NCGs yet
* Call expandCallishMachOp in the x86_64 codegen tooIan Lynagh2012-02-231-0/+4
| | | | | Currently it does nothing, as x86_64 supports all the callishMachOps that expandCallishMachOp expands, but it might be needed in the future.
* Add a primop for unsigned quotRem; part of #5598Ian Lynagh2012-02-173-15/+25
| | | | Only amd64 has an efficient implementation currently.
* Small refactorIan Lynagh2012-02-171-87/+92
| | | | Moved the default case of genCCall64 out into a separate function
* Define a quotRem CallishMachOp; fixes #5598Ian Lynagh2012-02-144-440/+447
| | | | | 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).
* de-tabbed the hs-boot filesIan Lynagh2012-01-261-9/+2
|
* Track STG live register information for use in LLVMDavid Terei2012-01-094-5/+5
| | | | | | | | | 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.

* Detect cases where as(1) doesn't recognise .ident directive (#5408)PHO2011-12-081-4/+7
| | | | .ident directives are usually ignored by as(1), and in some cases (like Darwin/PPC) they even raise an error.
* Get rid of the "safety" field of CmmCall (OldCmm)Simon Marlow2011-11-294-6/+6
| | | | | 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.

* Remove some old comments about the manglerDavid Terei2011-11-221-5/+0
|
* Better documentation for stack alignment designDavid Terei2011-11-171-25/+22
|
* Fix #4211: No need to fixup stack using mangler on OSXDavid Terei2011-11-171-3/+3
| | | | | | | We now manage the stack correctly on both x86 and i386, keeping the stack align at (16n bytes - word size) on function entry and at (16n bytes) on function calls. This gives us compatability with LLVM and GCC.
* Fix validate by moving OPTIONS -fno-warn-tabs Validate fixed for Mac OS X ↵Thorkil Naur2011-11-072-6/+6
| | | | 10.5 and Linux. For both: compiler/nativeGen/PPC/Instr.hs compiler/nativeGen/SPARC/Instr.hs failed to (stage1) build. For Mac OS X, but mysteriously not for Linux: compiler/basicTypes/Id.lhs compiler/basicTypes/Name.lhs failed during haddock'ing.
* Allow the use of R9 and R10 in primops; fixes trac #5423Ian Lynagh2011-11-063-0/+18

* Fix bitrotted NCG_DEBUG code, and switch to using a Haskell conditionalIan Lynagh2011-11-051-1/+2
|
* Use -fwarn-tabs when validatingIan Lynagh2011-11-0450-0/+351
| | | | | We only use it for "compiler" sources, i.e. not for libraries. Many modules have a -fno-warn-tabs kludge for now.
* Ignore stdcall c-call in native codegen on x86_64David M Peixotto2011-11-011-2/+3
| | | | | | | | | | | | | | The stdcall calling convention is not supported on x86_64. When an ffi import requests stdcall, a warning is issued as desired by #3336. However, the native codegen was still generating code that expected the callee to cleanup the stack arguments when calling a c function that requests stdcall. This patch changes the codegen to actually use the ccall calling convention as intended. Signed-off-by: David Terei <davidterei@gmail.com>
* Change stack alignment to 16+8 bytes in STG codeDavid M Peixotto2011-11-011-7/+9
| | | | | | | | | | | | | | | | | This patch changes the STG code so that %rsp to be aligned to a 16-byte boundary + 8. This is the alignment required by the x86_64 ABI on entry to a function. Previously we kept %rsp aligned to a 16-byte boundary, but this was causing problems for the LLVM backend (see #4211). We now don't need to invoke llvm stack mangler on x86_64 targets. Since the stack is now 16+8 byte algined in STG land on x86_64, we don't need to mangle the stack manipulations with the llvm mangler. This patch only modifies the alignement for x86_64 backends.
