* CMake: Make most target symbols hidden by defaultTom Stellard2020-01-146-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [Disassembler] Delete the VStream parameter of MCDisassembler::getInstruction()Fangrui Song2020-01-112-5/+5
| | | | | | | | | | The argument is llvm::null() everywhere except llvm::errs() in llvm-objdump in -DLLVM_ENABLE_ASSERTIONS=On builds. It is used by no target but X86 in -DLLVM_ENABLE_ASSERTIONS=On builds. If we ever have the needs to add verbose log to disassemblers, we can record log with a member function, instead of passing it around as an argument.
* CodeGen: Use LLT instead of EVT in getRegisterByNameMatt Arsenault2020-01-092-2/+2
| | | | | | Only PPC seems to be using it, and only checks some simple cases and doesn't distinguish between FP. Just switch to using LLT to simplify use from GlobalISel.

* [MC] Add parameter `Address` to MCInstPrinter::printInstFangrui Song2020-01-062-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | printInst prints a branch/call instruction as `b offset` (there are many variants on various targets) instead of `b address`. It is a convention to use address instead of offset in most external symbolizers/disassemblers. This difference makes `llvm-objdump -d` output unsatisfactory. Add `uint64_t Address` to printInst(), so that it can pass the argument to printInstruction(). `raw_ostream &OS` is moved to the last to be consistent with other print* methods. The next step is to pass `Address` to printInstruction() (generated by tablegen from the instruction set description). We can gradually migrate targets to print addresses instead of offsets. In any case, downstream projects which don't know `Address` can pass 0 as the argument. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D72172
* Revert "Honor -fuse-init-array when os is not specified on x86"Mitch Phillips2019-12-171-0/+1

* Fix assertion failure in getMemOperandWithOffsetWidthKristof Beyls2019-12-171-2/+4
| | | | | | | | | | | | | | | | | | | | This fixes an assertion failure that triggers inside getMemOperandWithOffset when Machine Sinking calls it on a MachineInstr that is not a memory operation. Different backends implement getMemOperandWithOffset differently: some return false on non-memory MachineInstrs, others assert. The Machine Sinking pass in at least SinkingPreventsImplicitNullCheck relies on getMemOperandWithOffset to return false on non-memory MachineInstrs, instead of asserting. This patch updates the documentation on getMemOperandWithOffset that it should return false on any MachineInstr it cannot handle, instead of asserting. It also adapts the in-tree backends accordingly where necessary. Differential Revision: https://reviews.llvm.org/D71359

* [ARM] Teach the Arm cost model that a Shift can be folded into other ↵David Green2019-12-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | instructions This attempts to teach the cost model in Arm that code such as: %s = shl i32 %a, 3 %a = and i32 %s, %b Can under Arm or Thumb2 become: and r0, r1, r2, lsl #3 So the cost of the shift can essentially be free. To do this without trying to artificially adjust the cost of the "and" instruction, it needs to get the users of the shl and check if they are a type of instruction that the shift can be folded into. And so it needs to have access to the actual instruction in getArithmeticInstrCost, which if available is added as an extra parameter much like getCastInstrCost. We otherwise limit it to shifts with a single user, which should hopefully handle most of the cases. The list of instruction that the shift can be folded into include ADC, ADD, AND, BIC, CMP, EOR, MVN, ORR, ORN, RSB, SBC and SUB. This translates to Add, Sub, And, Or, Xor and ICmp.

* [cmake] Explicitly mark libraries defined in lib/ as "Component Libraries"Tom Stellard2019-11-214-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Most libraries are defined in the lib/ directory but there are also a few libraries defined in tools/ e.g. libLLVM, libLTO. I'm defining "Component Libraries" as libraries defined in lib/ that may be included in libLLVM.so. Explicitly marking the libraries in lib/ as component libraries allows us to remove some fragile checks that attempt to differentiate between lib/ libraries and tools/ libraires: 1. In tools/llvm-shlib, because llvm_map_components_to_libnames(LIB_NAMES "all") returned a list of all libraries defined in the whole project, there was custom code needed to filter out libraries defined in tools/, none of which should be included in libLLVM.so. This code assumed that any library defined as static was from lib/ and everything else should be excluded. With this change, llvm_map_components_to_libnames(LIB_NAMES, "all") only returns libraries that have been added to the LLVM_COMPONENT_LIBS global cmake property, so this custom filtering logic can be removed. Doing this also fixes the build with BUILD_SHARED_LIBS=ON and LLVM_BUILD_LLVM_DYLIB=ON. 2. There was some code in llvm_add_library that assumed that libraries defined in lib/ would not have LLVM_LINK_COMPONENTS or ARG_LINK_COMPONENTS set. This is only true because libraries defined lib lib/ use LLVMBuild.txt and don't set these values. This code has been fixed now to check if the library has been explicitly marked as a component library, which should now make it easier to remove LLVMBuild at some point in the future. I have tested this patch on Windows, MacOS and Linux with release builds and the following combinations of CMake options: - "" (No options) - -DLLVM_BUILD_LLVM_DYLIB=ON - -DLLVM_LINK_LLVM_DYLIB=ON - -DBUILD_SHARED_LIBS=ON - -DBUILD_SHARED_LIBS=ON -DLLVM_BUILD_LLVM_DYLIB=ON - -DBUILD_SHARED_LIBS=ON -DLLVM_LINK_LLVM_DYLIB=ON Reviewers: beanz, smeenai, compnerd, phosek Reviewed By: beanz Subscribers: wuzish, jholewinski, arsenm, dschuff, jyknight, dylanmckay, sdardis, nemanjai, jvesely, nhaehnle, mgorny, mehdi_amini, sbc100, jgravelle-google, hiraditya, aheejin, fedor.sergeev, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, steven_wu, rogfer01, MartinMosbeck, brucehoult, the_o, dexonsmith, PkmX, jocewei, jsji, dang, Jim, lenary, s.egerton, pzheng, sameer.abuasal, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D70179

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [CodeGen] Add "const" to MachineInstr::mayAliasBjorn Pettersson2019-04-192-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | Summary: The basic idea here is to make it possible to use MachineInstr::mayAlias also when the MachineInstr is const (or the "Other" MachineInstr is const). The addition of const in MachineInstr::mayAlias then rippled down to the need for adding const in several other places, such as TargetTransformInfo::getMemOperandWithOffset.

* [AsmPrinter] refactor to remove remove AsmVariant. NFCNick Desaulniers2019-04-101-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [Lanai] Be super conservative about atomicsPhilip Reames2019-02-251-1/+2
| | | | | | | | As requested during review of D57601 <https://reviews.llvm.org/D57601>, be equally conservative for atomic MMOs as for volatile MMOs in all in tree backends. At the moment, all atomic MMOs are also volatile, but I'm about to change that. Reviewed as part of https://reviews.llvm.org/D58490, with other backends still pending review. llvm-svn: 354800
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-1956-224/+168
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [CodeGen][NFC] Make `TII::getMemOpBaseImmOfs` return a base operandFrancis Visoiu Mistrih2018-11-282-18/+21
| | | | | | | | | | | | | | | | | | Currently, instructions doing memory accesses through a base operand that is not a register can not be analyzed using `TII::getMemOpBaseRegImmOfs`. This means that functions such as `TII::shouldClusterMemOps` will bail out on instructions using an FI as a base instead of a register. The goal of this patch is to refactor all this to return a base operand instead of a base register. Then in a separate patch, I will add FI support to the mem op clustering in the MachineScheduler.
