* [SystemZ] Rename 32-bit GPR registersRichard Sandiford2013-09-306-20/+20
| | | | | | | | | I'm about to add support for high-word operations, so it seemed better for the low-word registers to have names like R0L rather than R0W. No behavioral change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191655 91177308-0d34-0410-b5e6-96231b3b80d8

* Various x86 disassembler fixes.Craig Topper2013-09-305-53/+66
| | | | | | | | | | | | | Add VEX_LIG to scalar FMA4 instructions. Use VEX_LIG in some of the inheriting checks in disassembler table generator. Make use of VEX_L_W, VEX_L_W_XS, VEX_L_W_XD contexts. Don't let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from their non-L forms unless VEX_LIG is set. Let VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE inherit from all of their non-L or non-W cases. Increase ranking on VEX_L_W, VEX_L_W_XS, VEX_L_W_XD, VEX_L_W_OPSIZE so they get chosen over non-L/non-W forms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191649 91177308-0d34-0410-b5e6-96231b3b80d8

* R600: Fix handling of NAN in comparison instructionsTom Stellard2013-09-2810-105/+127
| | | | | | | | | We were completely ignoring the unorder/ordered attributes of condition codes and also incorrectly lowering seto and setuo. Reviewed-by: Vincent Lejeune<vljn at ovi.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191603 91177308-0d34-0410-b5e6-96231b3b80d8
* SelectionDAG: Improve legalization of SELECT_CC with illegal condition codesTom Stellard2013-09-282-17/+49
| | | | | | | | | | | SelectionDAG will now attempt to inverse an illegal conditon in order to find a legal one and if that doesn't work, it will attempt to swap the operands using the inverted condition. There are no new test cases for this, but a nubmer of the existing R600 tests hit this path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191602 91177308-0d34-0410-b5e6-96231b3b80d8
* SelectionDAG: Try to expand all condition codes using getCCSwappedOperands()Tom Stellard2013-09-285-94/+91
| | | | | | | | | | | | This is useful for targets like R600, which only support GT, GE, NE, and EQ condition codes as it removes the need to handle unsupported condition codes in target specific code. There are no tests with this commit, but R600 has been updated to take advantage of this new feature, so its existing selectcc tests are now testing the swapped operands path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191601 91177308-0d34-0410-b5e6-96231b3b80d8
* SelectionDAG: Clean up LegalizeSetCCCondCode() functionTom Stellard2013-09-281-26/+51
| | | | | | | | | | | | | | Interpreting the results of this function is not very intuitive, so I cleaned it up to make it more clear whether or not a SETCC op was legalized and how it was legalized (either by swapping LHS and RHS or replacing with AND/OR). This patch does change functionality in the LHS and RHS swapping case, but unfortunately there are no in-tree tests for this. However, this patch is a prerequisite for R600 to take advantage of the LHS and RHS swapping, so tests will be added in subsequent commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191600 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Make sure loads from lazy-binding entries do not get CSE'd or hoisted outAkira Hatanaka2013-09-288-28/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | of loops. Previously, two consecutive calls to function "func" would result in the following sequence of instructions: 1. load $16, %got(func)($gp) // load address of lazy-binding stub. 2. move $25, $16 3. jalr $25 // jump to lazy-binding stub. 4. nop 5. move $25, $16 6. jalr $25 // jump to lazy-binding stub again. With this patch, the second call directly jumps to func's address, bypassing the lazy-binding resolution routine: 1. load $25, %got(func)($gp) // load address of lazy-binding stub. 2. jalr $25 // jump to lazy-binding stub. 3. nop 4. load $25, %got(func)($gp) // load resolved address of func. 5. jalr $25 // directly jump to func. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191591 91177308-0d34-0410-b5e6-96231b3b80d8

* TBAA: handle scalar TBAA format and struct-path aware TBAA format.Manman Ren2013-09-2728-110/+252
| | | | | | | | | | | | | | | | | Remove the command line argument "struct-path-tbaa" since we should not depend on command line argument to decide which format the IR file is using. Instead, we check the first operand of the tbaa tag node, if it is a MDNode, we treat it as struct-path aware TBAA format, otherwise, we treat it as scalar TBAA format. When clang starts to use struct-path aware TBAA format no matter whether struct-path-tbaa is no, and we can auto-upgrade existing bc files, the support for scalar TBAA format can be dropped. Existing testing cases are updated to use the struct-path aware TBAA format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191538 91177308-0d34-0410-b5e6-96231b3b80d8
* Transforms: Use getFirstNonPHI to set the insertion point for PHIsJustin Bogner2013-09-273-2/+33
| | | | | | | | | | We were previously using getFirstInsertionPt to insert PHI instructions when vectorizing, but getFirstInsertionPt also skips past landingpads, causing this to generate invalid IR. We can avoid this issue by using getFirstNonPHI instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191526 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Rein back the use of block operationsRichard Sandiford2013-09-275-143/+101
| | | | | | | | | | | | | | | The backend tries to use block operations like MVC, NC, OC and XC for simple scalar operations. For correctness reasons, it rejects any case in which the regions might partially overlap. However, for performance reasons, it should also reject cases where the regions might be equal, since the instruction might then not use the fast path. This fixes a performance regression seen in bzip2. We may want to limit the optimisation even more in future, or even remove it entirely, but I'll try with this for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191525 91177308-0d34-0410-b5e6-96231b3b80d8
* [SystemZ] Improve handling of PC-relative addressesRichard Sandiford2013-09-276-59/+127
| | | | | | | | | | | | | | | The backend previously folded offsets into PC-relative addresses whereever possible. That's the right thing to do when the address can be used directly in a PC-relative memory reference (using things like LRL). But if we have a register-based memory reference and need to load the PC-relative address separately, it's better to use an anchor point that could be shared with other accesses to the same area of the variable. Fixes a FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191524 91177308-0d34-0410-b5e6-96231b3b80d8
