* [SystemZ] Generalize RxSBG SRA caseRichard Sandiford2013-07-182-27/+74
| | | | | | | | | | The original code only folded SRA into ROTATE ... SELECTED BITS if there was no outer shift. This patch splits out that check and generalises it slightly. The extra cases aren't really that interesting, but this is paving the way for RNSBG support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186571 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Rename and formatting fixesRichard Sandiford2013-07-181-64/+61
| | | | | | | | | | | | | In hindsight, using "RISBG" for something that can be any type of R.SBG instruction was a bit confusing, so this renames it to RxSBG. That might not be the best choice either, since there is an instruction called RXSBG, but hopefully the lower-case letter stands out enough. While there I fixed a couple of GNUisms that had crept in -- sorry about that! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186569 91177308-0d34-0410-b5e6-96231b3b80d8

* PPC: Support dynamic allocas with large alignmentHal Finkel2013-07-183-27/+92
| | | | | | | | | | | | | | | Support for dynamic stack alignments in the PPC backend has been unfinished, in part because it depends on dynamic stack realignment (which I only just recently implemented fully). Now we can also support dynamic allocas with higher than the default target stack alignment (16 bytes). In order to round-up the requested size to the maximum requested alignment, we need an additional register to hold the rounded-up size. We're already using one scavenged register to hold the previous stack-pointer value (which needs to be stored with the signal-safe stdux update), and so when we have dynamic allocas and a large alignment, we allocate two emergency spill slots for the scavenger. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186562 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | We don't want cast and dyn_cast to work on temporaries. They don't extend lifetime like a direct bind to a reference would, so they can introduce hard to find bugs.

* PPC: Add base-pointer support to builtin setjmp/longjmpHal Finkel2013-07-177-52/+130
| | | | | | | | | | | | | | | | | | First, this changes the base-pointer implementation to remove an unnecessary complication (and one that is incompatible with how builtin SjLj is implemented): instead of using r31 as the base pointer when it is not needed as a frame pointer, now the base pointer will always be r30 when needed. Second, we introduce another pseudo register, BP, which is used just like the FP pseudo register to refer to the base register before we know for certain what register it will be. Third, we now save BP into the jmp_buf, and restore r30 from that slot in longjmp. If the function that called setjmp did not use a base pointer, then r30 will be overwritten by the setjmp-calling-function's restore code. FP restoration (which is restored into r31) works the same way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186545 91177308-0d34-0410-b5e6-96231b3b80d8

* Add FILE_SHARE_WRITE to openFileForRead.Rafael Espindola2013-07-171-1/+1
| | | | | | | | | | | | | | This should fix the windows bots. It looks like the failing tests are of the form prog1 > file prog2 file and prog2 fails trying to read the file.

* Tweak the cmake interaction between CMAKE_BUILD_TYPE and LLVM_ENABLE_ASSERTIONS.Duncan Sands2013-07-172-3/+3
| | | | | | | | | | | | | | | The issue is that CMAKE_BUILD_TYPE=RelWithDebInfo LLVM_ENABLE_ASSERTIONS=ON was not building with assertions enabled. (I was unable to find what in the LLVM source tree was adding -DNDEBUG to the build line in this case, so decided that it must be cmake itself that was adding it - this may depend on the cmake version). The fix treats any mode that is not Debug as being the same as Release for this purpose (previously it was being assumed that cmake would only add -DNDEBUG for Release and not for RelWithDebInfo or MinSizeRel). If other versions of cmake don't add -DNDEBUG for RelWithDebInfo then that's OK: with this change you just get a useless but harmless -UNDEBUG or -DNDEBUG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186499 91177308-0d34-0410-b5e6-96231b3b80d8

* PPC: Add CTR-register clobber to builtin setjmpHal Finkel2013-07-174-0/+59
| | | | | | | | | | | | | Because the builtin longjmp implementation uses a CTR-based indirect jump, when the control flow arrives at the builtin setjmp call, the CTR register has necessarily been clobbered. Correspondingly, this adds CTR to the list of implicit definitions of the builtin setjmp pseudo instruction. We don't need to add CTR to the implicit definitions of builtin longjmp because, even though it does clobber the CTR register, the control flow cannot return to inside the loop unless there is also a builtin setjmp call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186488 91177308-0d34-0410-b5e6-96231b3b80d8
