* AVX-512: added arithmetic and logical operations.Elena Demikhovsky2013-08-195-30/+478
| | | | | | | | ADD, SUB, MUL integer and FP types. OR, AND, XOR. Added embeded broadcast form for these instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188673 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Add negative integer absolute (load negative)Richard Sandiford2013-08-196-6/+169
| | | | | | | | | For now this matches the equivalent of (neg (abs ...)), which did hit a few times in projects/test-suite. We should probably also match cases where absolute-like selects are used with reversed arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188671 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Add support for sibling callsRichard Sandiford2013-08-199-175/+214
| | | | | | | | | | | | | | | | | | | This first cut is pretty conservative. The final argument register (R6) is call-saved, so we would need to make sure that the R6 argument to a sibling call is the same as the R6 argument to the calling function, which seems worth keeping as a separate patch. Saying that integer truncations are free means that we no longer use the extending instructions LGF and LLGF for spills in int-conv-09.ll and int-conv-10.ll. Instead we treat the registers as 64 bits wide and truncate them to 32-bits where necessary. I think it's unlikely we'd use LGF and LLGF for spills in other situations for the same reason, so I'm removing the tests rather than replacing them. The associated code is generic and applies to many more instructions than just LGF and LLGF, so there is no corresponding code removal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188669 91177308-0d34-0410-b5e6-96231b3b80d8

* Add ExpandFloatOp_FCOPYSIGN to handle ppcf128-related expansionsHal Finkel2013-08-193-0/+80
| | | | | | | | | | We had previously been asserting when faced with a FCOPYSIGN f64, ppcf128 node because there was no way to expand the FCOPYSIGN node. Because ppcf128 is the sum of two doubles, and the first double must have the larger magnitude, we can take the sign from the first double. As a result, in addition to fixing the crash, this is also an optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188655 91177308-0d34-0410-b5e6-96231b3b80d8

* Add the PPC fcpsgn instructionHal Finkel2013-08-197-9/+101
| | | | | | | | | Modern PPC cores support a floating-point copysign instruction, and we can use this to lower the FCOPYSIGN node (which is created from calls to the libm copysign function). A couple of extra patterns are necessary because the operand types of FCOPYSIGN need not agree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188653 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-dwarfdump: Do not include address offsets for attributes, only for tagsDavid Blaikie2013-08-198-21/+21
| | | | | | | | | This reduces the noise in diffs making it more likely that, at least for LLVM revision-over-revision, diffs will actually yield usable results.

* Fix SCEVExpander creating distinct duplicate PHI entriesHal Finkel2013-08-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes SCEVExpander so that it does not create multiple distinct induction variables for duplicate PHI entries. Specifically, given some code like this: do.body6: ; preds = %do.body6, %do.body6, %if.then5 %end.0 = phi i8* [ undef, %if.then5 ], [ %incdec.ptr, %do.body6 ], [ %incdec.ptr, %do.body6 ] ... Note that it is legal to have multiple entries for a basic block so long as the associated value is the same. So the above input is okay, but expanding an AddRec in this loop could produce code like this: do.body6: ; preds = %do.body6, %do.body6, %if.then5 %indvar = phi i64 [ %indvar.next, %do.body6 ], [ %indvar.next1, %do.body6 ], [ 0, %if.then5 ] %end.0 = phi i8* [ undef, %if.then5 ], [ %incdec.ptr, %do.body6 ], [ %incdec.ptr, %do.body6 ] ... %indvar.next = add i64 %indvar, 1 %indvar.next1 = add i64 %indvar, 1 And this is not legal because there are two PHI entries for %do.body6 each with a distinct value. Unfortunately, I don't have an in-tree test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188614 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: Fix more fast-isel verifier failures.Jim Grosbach2013-08-163-1/+48
| | | | | | | | | | | | | Teach the generic instruction selection helper functions to constrain the register classes of their input operands. For non-physical register references, the generic code needs to be careful not to mess that up when replacing references to result registers. As the comment indicates for MachineRegisterInfo::replaceRegWith(), it's important to call constrainRegClass() first. rdar://12594152 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188593 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: Clean up fast-isel machine verifier errors.Jim Grosbach2013-08-1610-42/+42
| | | | | | | | | | | | | Lots of machine verifier errors result from using a plain GPR regclass for incoming argument copies. A more restrictive rGPR class is more appropriate since it more accurately represents what's happening, plus it lines up better with isel later on so the verifier is happier. Reduces the number of ARM fast-isel tests not running with the verifier enabled by over half. rdar://12594152 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188592 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a subtle difference between running clang vs llc for mips16.Reed Kotler2013-08-162-0/+30
| | | | | | | | | | | | | | | | | | This regards how mips16 is viewed. It's not really a target type but there has always been a target for it in the td files. It's more properly -mcpu=mips32 -mattr=+mips16 . This is how clang treats it but we have always had the -mcpu=mips16 which I probably should delete now but it will require updating all the .ll test cases for mips16. In this case it changed how we decide if we have a count bits instruction and whether instruction lowering should then expand ctlz. Now that we have dual mode compilation, -mattr=+mips16 really just indicates the inital processor mode that we are compiling for. (It is also possible to have -mcpu=64 -mattr=+mips16 but as far as I know, nobody has even built such a processor, though there is an architecture manual for this). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188586 91177308-0d34-0410-b5e6-96231b3b80d8

* [PowerPC] Preparatory refactoring for making prologue and epilogueBill Schmidt2013-08-161-85/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | safe on PPC32 SVR4 ABI [Patch and following text by Mark Minich; committing on his behalf.] There are FIXME's in PowerPC/PPCFrameLowering.cpp, method PPCFrameLowering::emitPrologue() related to "negative offsets of R1" on PPC32 SVR4. They're true, but the real issue is that on PPC32 SVR4 (and any ABI without a Red Zone), no spills may be made until after the stackframe is claimed, which also includes the LR spill which is at a positive offset. The same problem exists in emitEpilogue(), though there's no FIXME for it. I intend to fix this issue, making LLVM-compiled code finally safe for use on SVR4/EABI/e500 32-bit platforms (including in particular, OS-free embedded systems & kernel code, where interrupts may share the same stack as user code). In preparation for making these changes, to make the diffs for the functional changes less cluttered, I am providing the non-functional refactorings in two stages: Stage 1 does some minor fluffy refactorings to pull multiple method calls up into a single bool, creating named bools for repeated uses of obscure logic, moving some code up earlier because either stage 2 or my final version will require it earlier, and rewording/adding some comments. My stage 1 changes can be characterized as primarily fluffy cleanup, the purpose of which may be unclear until the stage 2 or final changes are made. My stage 2 refactorings combine the separate PPC32 & PPC64 logic, which is currently performed by largely duplicate code, into a single flow, with the differences handled by a group of constants initialized early in the methods. This submission is for my stage 1 changes. There should be no functional changes whatsoever; this is a pure refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188573 91177308-0d34-0410-b5e6-96231b3b80d8
* Fixed RuntimeDyldELF absolute relocations.Richard Mitton2013-08-161-1/+11
| | | | | | | | | If an ELF relocation is pointed at an absolute address, it will have a symbol ID of zero. RuntimeDyldELF::processRelocationRef was not previously handling this case, and was instead trying to handle it as a section-relative fixup.
