* Add support for Thumb2 literal loads with negative zero offsetMihai Popa2013-08-162-4/+4
| | | | | | | | | | Thumb2 literal loads use an offset encoding which allows for negative zero. This fixes parsing and encoding so that #-0 is correctly processed. The parser represents #-0 as INT32_MIN. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188549 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix Thumb2 aliasing complementary instructions taking modified immediatesMihai Popa2013-08-162-5/+6
| | | | | | | | | | | | | | | | | | | | | | | There are many Thumb instructions which take 12-bit immediates encoded in a special 8-byte value + 4-byte rotator form. Not all numbers are represented, and it's legal to transform an assembly instruction to be able to encode the immediate. For example: AND and BIC are complementary instructions; one can switch the AND to a BIC as long as the immediate is complemented. The intent is to switch one instruction into its complementary one when the immediate cannot be encoded in the form requested in the original assembly and when the complementary immediate is encodable. The patch addresses two issues: 1. definition of t2SOImmNot immediate - it has to check that the orignal value is not encoded naturally 2. t2AND and t2BIC instruction aliases which should use the Thumb2 SOImm operand rather than the ARM one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188548 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Fix handling of 64-bit memcmp resultsRichard Sandiford2013-08-161-0/+7
| | | | | | | | | | | | | | Generalize r188163 to cope with return types other than MVT::i32, just as the existing visitMemCmpCall code did. I've split this out into a subroutine so that it can be used for other upcoming patches. I also noticed that I'd used the wrong API to record the out chain. It's a load that uses DAG.getRoot() rather than getRoot(), so the out chain should go on PendingLoads. I don't have a testcase for that because we don't do any interesting scheduling on z yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188540 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Fix sign of integer memcmp resultRichard Sandiford2013-08-162-36/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r188163 used CLC to implement memcmp. Code that compares the result directly against zero can test the CC value produced by CLC, but code that needs an integer result must use IPM. The sequence I'd used was: ipm <reg> sll <reg>, 2 sra <reg>, 30 but I'd forgotten that this inverts the order, so that CC==1 ("less") becomes an integer greater than zero, and CC==2 ("greater") becomes an integer less than zero. This sequence should only be used if the CLC arguments are reversed to compensate. The problem then is that the branch condition must also be reversed when testing the CLC result directly. Rather than do that, I went for a different sequence that works with the natural CLC order: ipm <reg> srl <reg>, 28 rll <reg>, <reg>, 31 One advantage of this is that it doesn't clobber CC. A disadvantage is that any sign extension to 64 bits must be done separately, rather than being folded into the shifts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188538 91177308-0d34-0410-b5e6-96231b3b80d8

* R600/SI: Fix incorrect encoding of DS_WRITE_B32 instructionsTom Stellard2013-08-163-10/+8
| | | | | | | | | The SIInsertWaits pass was overwriting the first operand (gds bit) of DS_WRITE_B32 with the second operand (value to write). This meant that any time the value to write was stored in an odd number VGPR, the gds bit would be set causing the instruction to write to GDS instead of LDS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188522 91177308-0d34-0410-b5e6-96231b3b80d8

* Let t2LDRBi8 and t2LDRBi12 have same Base PointerRenato Golin2013-08-141-1/+14
| | | | | | | | | | | | | | When determining if two different loads are from the same base address, this patch allows one load to use a t2LDRi8 address mode and another to use a t2LDRi12 address mode. The current implementation is very conservative and this allows the case of differing Thumb2 byte loads to be considered. Allowing these differing modes instead of forcing the exact same opcode is useful for situations where one opcodes loads from a base address+1 and a second opcode loads for a base address-1.
