* Intrinsics: expand semantics of LLVMExtendedVectorType (& trunc)Tim Northover2014-03-28
| | | | | | | | | | | | These are used in the ARM backends to aid type-checking on patterns involving intrinsics. By making sure one argument is an extended/truncated version of another. However, there's no reason to limit them to just vectors types. For example AArch64 has the instruction "uqshrn sD, dN, #imm" which would naturally use an intrinsic taking an i64 and returning an i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205003 91177308-0d34-0410-b5e6-96231b3b80d8

* Expose "noduplicate" attribute as a property for intrinsics.Eli Bendersky2014-03-18
| | | | | | | | | | | | | | The "noduplicate" function attribute exists to prevent certain optimizations from duplicating calls to the function. This is important on platforms where certain function call duplications are unsafe (for example execution barriers for CUDA and OpenCL). This patch makes it possible to specify intrinsics as "noduplicate" and translates that to the appropriate function attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204200 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the linker_private and linker_private_weak linkages.Rafael Espindola2014-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These linkages were introduced some time ago, but it was never very clear what exactly their semantics were or what they should be used for. Some investigation found these uses: * utf-16 strings in clang. * non-unnamed_addr strings produced by the sanitizers. It turns out they were just working around a more fundamental problem. For some sections a MachO linker needs a symbol in order to split the section into atoms, and llvm had no idea that was the case. I fixed that in r201700 and it is now safe to use the private linkage. When the object ends up in a section that requires symbols, llvm will use a 'l' prefix instead of a 'L' prefix and things just work. With that, these linkages were already dead, but there was a potential future user in the objc metadata information. I am still looking at CGObjcMac.cpp, but at this point I am convinced that linker_private and linker_private_weak are not what they need. The objc uses are currently split in * Regular symbols (no '\01' prefix). LLVM already directly provides whatever semantics they need. * Uses of a private name (start with "\01L" or "\01l") and private linkage. We can drop the "\01L" and "\01l" prefixes as soon as llvm agrees with clang on L being ok or not for a given section. I have two patches in code review for this. * Uses of private name and weak linkage. The last case is the one that one could think would fit one of these linkages. That is not the case. The semantics are * the linker will merge these symbol by *name*. * the linker will hide them in the final DSO. Given that the merging is done by name, any of the private (or internal) linkages would be a bad match. They allow llvm to rename the symbols, and that is really not what we want. From the llvm point of view, these objects should really be (linkonce|weak)(_odr)?. For now, just keeping the "\01l" prefix is probably the best for these symbols. If we one day want to have a more direct support in llvm, IMHO what we should add is not a linkage, it is just a hidden_symbol attribute. It would be applicable to multiple linkages. For example, on weak it would produce the current behavior we have for objc metadata. On internal, it would be equivalent to private (and we should then remove private). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203866 91177308-0d34-0410-b5e6-96231b3b80d8

* [TableGen] Optionally forbid overlap between named and positional operandsHal Finkel2014-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are currently two schemes for mapping instruction operands to instruction-format variables for generating the instruction encoders and decoders for the assembler and disassembler respectively: a) to map by name and b) to map by position. In the long run, we'd like to remove the position-based scheme and use only name-based mapping. Unfortunately, the name-based scheme currently cannot deal with complex operands (those with suboperands), and so we currently must use the position-based scheme for those. On the other hand, the position-based scheme cannot deal with (register) variables that are split into multiple ranges. An upcoming commit to the PowerPC backend (adding VSX support) will require this capability. While we could teach the position-based scheme to handle that, since we'd like to move away from the position-based mapping generally, it seems silly to teach it new tricks now. What makes more sense is to allow for partial transitioning: use the name-based mapping when possible, and only use the position-based scheme when necessary. Now the problem is that mixing the two sensibly was not possible: the position-based mapping would map based on position, but would not skip those variables that were mapped by name. Instead, the two sets of assignments would overlap. However, I cannot currently change the current behavior, because there are some backends that rely on it [I think mistakenly, but I'll send a message to llvmdev about that]. So I've added a new TableGen bit variable: noNamedPositionallyEncodedOperands, that can be used to cause the position-based mapping to skip variables mapped by name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203767 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace PROLOG_LABEL with a new CFI_INSTRUCTION.Rafael Espindola2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | The old system was fairly convoluted: * A temporary label was created. * A single PROLOG_LABEL was created with it. * A few MCCFIInstructions were created with the same label. The semantics were that the cfi instructions were mapped to the PROLOG_LABEL via the temporary label. The output position was that of the PROLOG_LABEL. The temporary label itself was used only for doing the mapping. The new CFI_INSTRUCTION has a 1:1 mapping to MCCFIInstructions and points to one by holding an index into the CFI instructions of this function. I did consider removing MMI.getFrameInstructions completelly and having CFI_INSTRUCTION own a MCCFIInstruction, but MCCFIInstructions have non trivial constructors and destructors and are somewhat big, so the this setup is probably better. The net result is that we don't create temporary labels that are never used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203204 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an OutPatFrag TableGen classHal Finkel2014-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, it is currently impossible to use a PatFrag as part of an output pattern (the part of the pattern that has instructions in it) in TableGen. Looking at the current implementation, this was clearly intended to work (there is already code in place to expand patterns in the output DAG), but is currently broken by the baked-in type-checking assumption and the order in which the pattern fragments are processed (output pattern fragments need to be processed after the instruction definitions are processed). Fixing this is fairly simple, but requires some way of differentiating output patterns from the existing input patterns. The simplest way to handle this seems to be to create a subclass of PatFrag, and so that's what I've done here. As a simple example, this allows us to write: def crnot : OutPatFrag<(ops node:$in), (CRNOR $in, $in)>; def : Pat<(not i1:$in), (crnot $in)>; which captures the core use case: handling of repeated subexpressions inside of complicated output patterns. This will be used by an upcoming commit to the PowerPC backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202450 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | Hence, they should not be marked nounwind. Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind data for that matter), making deoptimization via stackmaps impossible.
