* CodeGen: Introduce a class for registersMatt Arsenault2019-06-242-2/+2
| | | | | | | | | Avoids using a plain unsigned for registers throughoug codegen. Doesn't attempt to change every register use, just something a little more than the set needed to build after changing the return type of MachineOperand::getReg(). llvm-svn: 364191
* [TargetLowering] Add allowsMemoryAccess(MachineMemOperand) helper wrapper. NFCI.Simon Pilgrim2019-06-111-2/+2
| | | | | | As suggested by @arsenm on D63075 - this adds a TargetLowering::allowsMemoryAccess wrapper that takes a Load/Store node's MachineMemOperand to handle the AddressSpace/Alignment arguments and will also implicitly handle the MachineMemOperand::Flags change in D63075. llvm-svn: 363048
* Revert CMake: Make most target symbols hidden by defaultTom Stellard2019-06-114-4/+4
| | | | | | | | | | | | | | | This reverts r362990 (git commit 374571301dc8e9bc9fdd1d70f86015de198673bd) This was causing linker warnings on Darwin: ld: warning: direct access in function 'llvm::initializeEvexToVexInstPassPass(llvm::PassRegistry&)' from file '../../lib/libLLVMX86CodeGen.a(X86EvexToVex.cpp.o)' to global weak symbol 'void std::__1::__call_once_proxy<std::__1::tuple<void* (&)(llvm::PassRegistry&), std::__1::reference_wrapper<llvm::PassRegistry>&&> >(void*)' from file '../../lib/libLLVMCore.a(Verifier.cpp.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings. llvm-svn: 363028
* CMake: Make most target symbols hidden by defaultTom Stellard2019-06-104-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: For builds with LLVM_BUILD_LLVM_DYLIB=ON and BUILD_SHARED_LIBS=OFF this change makes all symbols in the target specific libraries hidden by default. A new macro called LLVM_EXTERNAL_VISIBILITY has been added to mark symbols in these libraries public, which is mainly needed for the definitions of the LLVMInitialize* functions. This patch reduces the number of public symbols in libLLVM.so by about 25%. This should improve load times for the dynamic library and also make abi checker tools, like abidiff require less memory when analyzing libLLVM.so One side-effect of this change is that for builds with LLVM_BUILD_LLVM_DYLIB=ON and LLVM_LINK_LLVM_DYLIB=ON some unittests that access symbols that are no longer public will need to be statically linked.

* [AsmPrinter] refactor to support %c w/ GlobalAddress'Nick Desaulniers2019-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Targets like ARM, MSP430, PPC, and SystemZ have complex behavior when printing the address of a MachineOperand::MO_GlobalAddress. Move that handling into a new overriden method in each base class. A virtual method was added to the base class for handling the generic case. Refactors a few subclasses to support the target independent %a, %c, and %n. The patch also contains small cleanups for AVRAsmPrinter and SystemZAsmPrinter. It seems that NVPTXTargetLowering is possibly missing some logic to transform GlobalAddressSDNodes for TargetLowering::LowerAsmOperandForConstraint to handle with "i" extended inline assembly asm constraints.

* [CUDA] Implemented _[bi]mma* builtins.Artem Belevich2019-04-251-0/+2
| | | | | | | | | | | | | | | | These builtins provide access to the new integer and sub-integer variants of MMA (matrix multiply-accumulate) instructions provided by CUDA-10.x on sm_75 (AKA Turing) GPUs. Also added a feature for PTX 6.4. While Clang/LLVM does not generate any PTX instructions that need it, we still need to pass it through to ptxas in order to be able to compile code that uses the new 'mma' instruction as inline assembly (e.g used by NVIDIA's CUTLASS library https://github.com/NVIDIA/cutlass/blob/master/cutlass/arch/mma.h#L101) Differential Revision: https://reviews.llvm.org/D60279 llvm-svn: 359248
* PTX 6.3 extends `wmma` instruction to support s8/u8/s4/u4/b1 -> s32.Artem Belevich2019-04-253-54/+243
| | | | | | | | | | | | All of the new instructions are still handled mostly by tablegen. I've slightly refactored the code to drive intrinsic/instruction generation from a master list of supported variants, so all irregularities have to be implemented in one place only. The test generation script wmma.py has been refactored in a similar way. Differential Revision: https://reviews.llvm.org/D60015 llvm-svn: 359247
* [NVPTX] generate correct MMA instruction mnemonics with PTX63+.Artem Belevich2019-04-254-129/+170
| | | | | | | | | | | PTX 6.3 requires using ".aligned" in the MMA instruction names. In order to generate correct name, now we pass current PTX version to each instruction as an extra constant operand and InstPrinter adjusts its output accordingly.

* [NVPTX] Refactor generation of MMA intrinsics and instructions. NFC.Artem Belevich2019-04-251-329/+183
| | | | | | | | | | | | | | | Generalized constructions of 'fragments' of MMA operations to provide common primitives for construction of the ops. This will make it easier to add new variants of the instructions that operate on integer types. Use nested foreach loops which makes it possible to better control naming of the intrinsics. This patch does not affect LLVM's output, so there are no test changes. Differential Revision: https://reviews.llvm.org/D59389 llvm-svn: 359245
* Add "const" in GetUnderlyingObjects. NFCBjorn Pettersson2019-04-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Both the input Value pointer and the returned Value pointers in GetUnderlyingObjects are now declared as const. It turned out that all current (in-tree) uses of GetUnderlyingObjects were trivial to update, being satisfied with have those Value pointers declared as const. Actually, in the past several of the users had to use const_cast, just because of ValueTracking not providing a version of GetUnderlyingObjects with "const" Value pointers. With this patch we get rid of those const casts.

* [NVPTXAsmPrinter] clean up dead code. NFCNick Desaulniers2019-04-162-45/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The printOperand function takes a default parameter, for which there are zero call sites that explicitly pass such a parameter. As such, there is no case to support. This means that the method printVecModifiedImmediate is purly dead code, and can be removed. The eventual goal for some of these AsmPrinter refactoring is to have printOperand be a virtual method; making it easier to print operands from the base class for more generic Asm printing. It will help if all printOperand methods have the same function signature (ie. no Modifier argument when not needed).

* [AsmPrinter] refactor to remove remove AsmVariant. NFCNick Desaulniers2019-04-102-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: The InlineAsm::AsmDialect is only required for X86; no architecture makes use of it and as such it gets passed around between arch-specific and general code while being unused for all architectures but X86. Since the AsmDialect is queried from a MachineInstr, which we also pass around, remove the additional AsmDialect parameter and query for it deep in the X86AsmPrinter only when needed/as late as possible. This refactor should help later planned refactors to AsmPrinter, as this difference in the X86AsmPrinter makes it harder to make AsmPrinter more generic.

* [NVPTX] Fix the codegen for llvm.round.Bixia Zheng2019-04-013-10/+107
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously, we translate llvm.round to PTX cvt.rni, which rounds to the even interger when the source is equidistant between two integers. This is not correct as llvm.round should round away from zero. This change replaces llvm.round with a round away from zero implementation through target specific custom lowering. Modify a few affected tests to not check for cvt.rni. Instead, we check for the use of a few constants used in implementing round. We are also adding CUDA runnable tests to check for the values produced by llvm.round to test-suites/External/CUDA.

* [NVPTX] Allow libcalls that are defined in the current module.Justin Lebar2018-12-268-4/+202
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds a possibility to make library calls on NVPTX. An important thing about library functions - they must be defined within the current module. This basically should guarantee that we produce a valid PTX assembly (without calls to not defined functions). The one who wants to use the libcalls is probably will have to link against compiler-rt or any other implementation. Currently, it's completely impossible to make library calls because of error LLVM ERROR: Cannot select: i32 = ExternalSymbol '...'. But we can lower ExternalSymbol to TargetExternalSymbol and verify if the function definition is available. Also, there was an issue with a DAG during legalisation. When we expand instruction into libcall, the inner call-chain isn't being "integrated" into outer chain. Since the last "data-flow" (call retval load) node is located in call-chain earlier than CALLSEQ_END node, the latter becomes a leaf and therefore a dead node (and is being removed quite fast). Proposed here solution relies on another data-flow pseudo nodes (ProxyReg) which purpose is only to keep CALLSEQ_END at legalisation and instruction selection phases - we remove the pseudo instructions before register scheduling phase.

NVPTX target allows to represent the vector of the data of the same type as a vector, where values are separated using `,` symbol: `.b8 <data1>,<data2>,...`.

This is the biggest remaining chunk of the usage of `getTerminator()` that insists on the narrow type and so is an easy batch of updates.

All of these were trivial in nature (pervasively using `Instruction` instead just worked). llvm-svn: 344502
