* 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 Song2020-01-111-4/+4
| | | | | | | | | | 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

* [XCore] Create a TargetInfo header. NFCRichard Trieu2019-05-151-4/+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: 360738
* 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

* Pass an ArrayRef to MCDisassembler::getInstruction.Rafael Espindola2014-11-121-13/+8
| | | | | | | | | | | | With this patch MCDisassembler::getInstruction takes an ArrayRef<uint8_t> instead of a MemoryObject. Even on X86 there is a maximum size an instruction can have. Given that, it seems way simpler and more efficient to just pass an ArrayRef to the disassembler instead of a MemoryObject and have it do a virtual call every time it wants some extra bytes. llvm-svn: 221751

* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. llvm-svn: 206822
* [MC] Require an MCContext when constructing an MCDisassembler.Lang Hames2014-04-151-7/+8
| | | | | | | | | | | | | | | | This patch re-introduces the MCContext member that was removed from MCDisassembler in r206063, and requires that an MCContext be passed in at MCDisassembler construction time. (Previously the MCContext member had been initialized in an ad-hoc fashion after construction). The MCCContext member can be used by MCDisassembler sub-classes to construct constant or target-specific MCExprs. This patch updates disassemblers for in-tree targets, and provides the MCRegisterInfo instance that some disassemblers were using through the MCContext (previously those backends were constructing their own MCRegisterInfo instances). llvm-svn: 206241
