* [ARM] Add ADD tests for Thumb2 narrowing (nfc)Scott Douglass2015-07-091-1/+67
| | | | | | Differential Revision: http://reviews.llvm.org/D11053 llvm-svn: 241798
* Test for 241794 (nest attribute in AArch64)Renato Golin2015-07-091-0/+23
| | | | | | | | Forgot to git add the test. Patch by Stephen Cross. llvm-svn: 241797
* Add support for nest attribute to AArch64 backendRenato Golin2015-07-091-0/+5
| | | | | | | | | | | | | | | The nest attribute is currently supported on the x86 (32-bit) and x86-64 backends, but not on ARM (32-bit) or AArch64. This patch adds support for nest to the AArch64 backend. Register x18 is used by GCC for this purpose and hence is used here. As discussed on the GCC mailing list the register choice is an ABI issue and so choosing the same register as GCC means __builtin_call_with_static_chain is compatible. Patch by Stephen Cross. llvm-svn: 241794
* Add getSizeInBits function to the APFloat classTamas Berghammer2015-07-092-8/+19

* Fix shift legalization and lowering for big constants.Pawel Bylica2015-07-094-19/+62
| | | | | | | | | | | | Summary: If shift amount is a constant value > 64 bit it is handled incorrectly during type legalization and X86 lowering. This patch the type of shift amount argument in function DAGTypeLegalizer::ExpandShiftByConstant from unsigned to APInt.

* Extended syntax of vector version of getelementptr instruction.Elena Demikhovsky2015-07-099-36/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | The justification of this change is here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/082989.html According to the current GEP syntax, vector GEP requires that each index must be a vector with the same number of elements. %A = getelementptr i8, <4 x i8*> %ptrs, <4 x i64> %offsets In this implementation I let each index be or vector or scalar. All vector indices must have the same number of elements. The scalar value will mean the splat vector value. (1) %A = getelementptr i8, i8* %ptr, <4 x i64> %offsets or (2) %A = getelementptr i8, <4 x i8*> %ptrs, i64 %offset In all cases the %A type is <4 x i8*> In the case (2) we add the same offset to all pointers. The case (1) covers C[B[i]] case, when we have the same base C and different offsets B[i]. The documentation is updated. http://reviews.llvm.org/D10496 llvm-svn: 241788

* [LAA] Rename IsRTNeeded to IsRTCheckAnalysisNeededAdam Nemet2015-07-091-6/+17
| | | | | | | | | | | | The original name was too close to NeedRTCheck which is what the actual memcheck analysis returns. This flag, as the new name suggests, is only used to whether to initiate that analysis. Also a comment is added to answer one question I had about this code for a long time. Namely, how does this flag differ from isDependencyCheckNeeded since they are seemingly set at the same time. llvm-svn: 241784

* Redirect DataLayout from TargetMachine to Module in ComputeValueVTs()Mehdi Amini2015-07-0916-104/+113
| | | | | | | | | | | | | | | | | | | | Summary: Avoid using the TargetMachine owned DataLayout and use the Module owned one instead.

* [LAA] Revert a small part of r239295Adam Nemet2015-07-082-6/+62
| | | | | | | | | | | | | | | | This commit ([LAA] Fix estimation of number of memchecks) regressed the logic a bit. We shouldn't quit the analysis if we encounter a pointer without known bounds *unless* we actually need to emit a memcheck for it. The original code was using NumComparisons which is now computed differently. Instead I compute NeedRTCheck from NumReadPtrChecks and NumWritePtrChecks. As side note, I find the separation of NeedRTCheck and CanDoRT confusing, so I will try to merge them in a follow-up patch. llvm-svn: 241756

* [Win64] Only treat some functions as having the Win64 conventionReid Kleckner2015-07-082-2/+38
| | | | | | | | | | | | | | | | All the usual X86 target-specific conventions are collapsed to the normal Win64 convention, but the custom conventions like GHC and webkit should not be. Previously we would assume that the caller allocated 32 bytes of shadow space for us, which is not how webkit_jscc or other custom conventions are supposed to work. Based on a patch by peavo@outlook.com. Fixes PR24051. llvm-svn: 241725
* Start adding support for writing archives in BSD format.Rafael Espindola2015-07-085-16/+69
| | | | | | | | No support for the symbol table yet (but will hopefully add it today). We always use the long filename format so that we can align the member, which is an advantage of the BSD format. llvm-svn: 241721
* MIR Parser: Use source locations for MBB naming errors.Alex Lorenz2015-07-084-9/+23
| | | | | | | | | This commit changes the type of the field 'Name' in the struct 'yaml::MachineBasicBlock' from 'std::string' to 'yaml::StringValue'. This change allows the MIR parser to report errors related to the MBB name with the proper source locations. llvm-svn: 241718

| | | | | | | | | The inferred output file name is based on the first input file, not the first one with extension .obj. The output file was also being written to the wrong directory; it needs to be written to whichever directory on the libpath it was found in. This change fixes both issues. llvm-svn: 241710
