* CMake: Make most target symbols hidden by defaultTom Stellard2020-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Song2020-01-111-2/+0
| | | | | | | | | | 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.
* [cmake] Explicitly mark libraries defined in lib/ as "Component Libraries"Tom Stellard2019-11-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Revert CMake: Make most target symbols hidden by defaultTom Stellard2019-06-111-1/+1
| | | | | | | | | | | | | | | 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

* [Sparc] Create a TargetInfo header. NFCRichard Trieu2019-05-151-6/+1
| | | | | | | | Move the declarations of getThe<Name>Target() functions into a new header in TargetInfo and make users of these functions include this new header. This fixes a layering problem. llvm-svn: 360733
* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-192-8/+6
| | | | | | | | | | | | | | | | | 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

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787

| | | | | | | | | | | | | | | | the Sparc back-end. This will allow inline assembler code to utilize these features, but no automatic lowering is provided, except for the previously provided @llvm.trap, which lowers to "ta 5". The change also separates out the different assembly language syntaxes for V8 and V9 Sparc. Previously, only V9 Sparc assembly syntax was provided. The change also corrects the selection order of trap disassembly, allowing, e.g. "ta %g0 + 15" to be rendered, more readably, as "ta 15", ignoring the %g0 register. This is per the sparc v8 and v9 manuals. Check-in includes many extra unit tests to check this works correctly on both V8 and V9 Sparc processors.

* [Sparc] Implement i64 load/store support for 32-bit sparc.James Y Knight2015-08-101-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LDD/STD instructions can load/store a 64bit quantity from/to memory to/from a consecutive even/odd pair of (32-bit) registers. They are part of SparcV8, and also present in SparcV9. (Although deprecated there, as you can store 64bits in one register). As recommended on llvmdev in the thread "How to enable use of 64bit load/store for 32bit architecture" from Apr 2015, I've modeled the 64-bit load/store operations as working on a v2i32 type, rather than making i64 a legal type, but with few legal operations. The latter does not (currently) work, as there is much code in llvm which assumes that if i64 is legal, operations like "add" will actually work on it. The same assumption does not hold for v2i32 -- for vector types, it is workable to support only load/store, and expand everything else. This patch: - Adds a new register class, IntPair, for even/odd pairs of registers. - Modifies the list of reserved registers, the stack spilling code, and register copying code to support the IntPair register class. - Adds support in AsmParser. (note that in asm text, you write the name of the first register of the pair only. So the parser has to morph the single register into the equivalent paired register). - Adds the new instructions themselves (LDD/STD/LDDA/STDA). - Hooks up the instructions and registers as a vector type v2i32. Adds custom legalizer to transform i64 load/stores into v2i32 load/stores and bitcasts, so that the new instructions can actually be generated, and marks all operations other than load/store on v2i32 as needing to be expanded. - Copies the unfortunate SelectInlineAsm hack from ARMISelDAGToDAG. This hack undoes the transformation of i64 operands into two arbitrarily-allocated separate i32 registers in SelectionDAGBuilder. and instead passes them in a single IntPair. (Arbitrarily allocated registers are not useful, asm code expects to be receiving a pair, which can be passed to ldd/std.) Also adds a bunch of test cases covering all the bugs I've added along the way. Differential Revision: http://reviews.llvm.org/D8713 llvm-svn: 244484

* Sparc: Add the "alternate address space" load/store instructions.James Y Knight2015-05-181-0/+11
| | | | | | | | | | | | | | | | | | - Adds support for the asm syntax, which has an immediate integer "ASI" (address space identifier) appearing after an address, before a comma. - Adds the various-width load, store, and swap in alternate address space instructions. (ldsba, ldsha, lduba, lduha, lda, stba, stha, sta, swapa) This does not attempt to hook these instructions up to pointer address spaces in LLVM, although that would probably be a reasonable thing to do in the future.
