2013-04-02[mips] Small update to the implementation of eh.return for Mips.Akira Hatanaka
This patch initializes t9 to the handler address, but only if the relocation model is pic. This handles the case where handler to which eh.return jumps points to the start of the function. Patch by Sasa Stankovic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178588 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[mips] Expand pseudo multiply/divide instructions in MipsCodeEmitter.cpp.Akira Hatanaka
This patch fixes the following two tests which have been failing on llvm-mips-linux builder since r178403: LLVM :: Analysis/Profiling/load-branch-weights-ifs.ll LLVM :: Analysis/Profiling/load-branch-weights-loops.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178584 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02[ms-inline asm] Add support for parsing variables with namespace aliasChad Rosier
qualifiers. This patch only adds support for parsing these identifiers in the X86AsmParser. The front-end interface isn't capable of looking up these identifiers at this point in time. The end result is the compiler now errors during object file emission, rather than at parse time. Test case coming shortly.

2013-04-02Fix PR15630: Replace faulty stdcx. with stwcx.Bill Schmidt
When doing a partword atomic operation, a lwarx was being paired with a stdcx. instead of a stwcx. when compiling for a 64-bit target. The target has nothing to do with it in this case; we always need a stwcx. Thanks to Kai Nacke for reporting the problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178559 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-02Add 64-bit load and store instructions.Jakob Stoklund Olesen

2013-04-02Basic 64-bit ALU operations.Jakob Stoklund Olesen
SPARC v9 extends all ALU instructions to 64 bits, so we simply need to add patterns to use them for both i32 and i64 values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178527 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Materialize 64-bit immediates.Jakob Stoklund Olesen
The last resort pattern produces 6 instructions, and there are still opportunities for materializing some immediates in fewer instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178526 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add 64-bit shift instructions.Jakob Stoklund Olesen
SPARC v9 defines new 64-bit shift instructions. The 32-bit shift right instructions are still usable as zero and sign extensions. This adds new F3_Sr and F3_Si instruction formats that probably should be used for the 32-bit shifts as well. They don't really encode an simm13 field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178525 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add predicates for distinguishing 32-bit and 64-bit modes.Jakob Stoklund Olesen
The 'sparc' architecture produces 32-bit code while 'sparcv9' produces 64-bit code. It is also possible to run 32-bit code using SPARC v9 instructions with: llc -march=sparc -mattr=+v9 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178524 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add support for 64-bit calling convention.Jakob Stoklund Olesen
This is far from complete, but it is enough to make it possible to write test cases using i64 arguments. Missing features: - Floating point arguments. - Receiving arguments on the stack. - Calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178523 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Add an I64Regs register class for 64-bit registers.Jakob Stoklund Olesen
We are going to use the same registers for 32-bit and 64-bit values, but in two different register classes. The I64Regs register class has a larger spill size and alignment. The addition of an i64 register class confuses TableGen's type inference, so it is necessary to clarify the type of some immediates and the G0 register. In 64-bit mode, pointers are i64 and should use the I64Regs register class. Implement getPointerRegClass() to dynamically provide the pointer register class depending on the subtarget. Use ptr_rc and iPTR for memory operands. Finally, add the i64 type to the IntRegs register class. This register class is not used to hold i64 values, I64Regs is for that. The type is required to appease TableGen's type checking in output patterns like this: def : Pat<(add i64:$a, i64:$b), (ADDrr $a, $b)>; SPARC v9 uses the same ADDrr instruction for i32 and i64 additions, and TableGen doesn't know to check the type of register sub-classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178522 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-02The divide unit is not pipeline, but it is still buffered.Andrew Trick
Buffered means a later divide may be executed out-of-order while a prior divide is sitting (buffered) in a reservation station. You can tell it's not pipelined, because operations that use it reserve it for more than one cycle: def : WriteRes<WriteIDiv, [HWPort0, HWDivider]> { let Latency = 25; let ResourceCycles = [1, 10]; } We don't currently distinguish between an unpipeline operation and one that is split into multiple micro-ops requiring the same unit. Except that the later may have NumMicroOps > 1 if they also consume issue/dispatch resources. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178519 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-01Add more PPC floating-point conversion instructionsHal Finkel
The P7 and A2 have additional floating-point conversion instructions which allow a direct two-instruction sequence (plus load/store) to convert from all combinations (signed/unsigned i32/i64) <--> (float/double) (on previous cores, only some combinations were directly available). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178480 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-01Add the PPC popcntw instructionHal Finkel
The popcntw instruction is available whenever the popcntd instruction is available, and performs a separate popcnt on the lower and upper 32-bits. Ignoring the high-order count, this can be used for the 32-bit input case (saving on the explicit zero extension otherwise required to use popcntd). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178470 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-01Treat PPCISD::STFIWX like the memory opcode that it isHal Finkel
PPCISD::STFIWX is really a memory opcode, and so it should come after FIRST_TARGET_MEMORY_OPCODE, and we should use DAG.getMemIntrinsicNode to create nodes using it. No functionality change intended (although there could be optimization benefits from preserving the MMO information). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178468 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-31Cleanup ImmToIdxMap and noImmForm in PPCRegisterInfoHal Finkel
ImmToIdxMap should be a DenseMap (not a std::map) because there is no ordering requirement. Also, we don't need a separate list of instructions for noImmForm in eliminateFrameIndex, because this list is essentially the complement of the keys in ImmToIdxMap. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178450 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-31Add the PPC lfiwax instructionHal Finkel
This instruction is available on modern PPC64 CPUs, and is now used to improve the SINT_TO_FP lowering (by eliminating the need for the separate sign extension instruction and decreasing the amount of needed stack space). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178446 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-31Cleanup PPC(64) i32 -> float/double conversionHal Finkel
The existing SINT_TO_FP code for i32 -> float/double conversion was disabled because it relied on broken EXTSW_32/STD_32 instruction definitions. The original intent had been to enable these 64-bit instructions to be used on CPUs that support them even in 32-bit mode. Unfortunately, this form of lying to the infrastructure was buggy (as explained in the FIXME comment) and had therefore been disabled. This re-enables this functionality, using regular DAG nodes, but only when compiling in 64-bit mode. The old STD_32/EXTSW_32 definitions (which were dead) are removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178438 91177308-0d34-0410-b5e6-96231b3b80d8
