* [MCJIT] Fix an iterator invalidation bug in MCJIT::finalizeObject.Lang Hames2014-09-051-5/+7
| | | | | | | | | | | The finalizeObject method calls generateCodeForModule on each of the currently 'added' objects, but generateCodeForModule moves objects out of the 'added' set as it's called. To avoid iterator invalidation issues, the added set is copied out before any calls to generateCodeForModule. This should fix http://llvm.org/PR20851 . llvm-svn: 217291

* Give ExecutionEngine of top level buffers.Rafael Espindola2014-08-261-3/+5
| | | | | | | Long term the idea if for the engine to not own the buffers, but for now this is consistent with the rest of the API. llvm-svn: 216484
* Don't own the buffer in object::Binary.Rafael Espindola2014-08-191-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries (like Archive) and we had to create dummy buffers just to handle that. It is also a bad fit for IRObjectFile where the Module wants to own the buffer too. Keeping this ownership would make supporting IR inside native objects particularly painful. This patch focuses in lib/Object. If something elsewhere used to own an Binary, now it also owns a MemoryBuffer. This patch introduces a few new types. * MemoryBufferRef. This is just a pair of StringRefs for the data and name. This is to MemoryBuffer as StringRef is to std::string. * OwningBinary. A combination of Binary and a MemoryBuffer. This is needed for convenience functions that take a filename and return both the buffer and the Binary using that buffer. The C api now uses OwningBinary to avoid any change in semantics. I will start a new thread to see if we want to change it and how. llvm-svn: 216002

* Revert "Replace Execution Engine's mutex with std::recursive_mutex."Zachary Turner2014-06-201-18/+19
| | | | | | | | | | This reverts commit 1f502bd9d7d2c1f98ad93a09ffe435e11a95aedd, due to GCC / MinGW's lack of support for C++11 threading. It's possible this will go back in after we come up with a reasonable solution. llvm-svn: 211401
* Replace Execution Engine's mutex with std::recursive_mutex.Zachary Turner2014-06-181-19/+18
| | | | | | | | | | | | | This change has a bit of a trickle down effect due to the fact that there are a number of derived implementations of ExecutionEngine, and that the mutex is not tightly encapsulated so is used by other classes directly.

* PR19553: Memory leak in RuntimeDyldELF::createObjectImageFromFileDavid Blaikie2014-04-291-5/+5
| | | | | | | | | | | | | | | | This starts in MCJIT::getSymbolAddress where the unique_ptr<object::Binary> is release()d and (after a cast) passed to a single caller, MCJIT::addObjectFile. addObjectFile calls RuntimeDyld::loadObject. RuntimeDld::loadObject calls RuntimeDyldELF::createObjectFromFile And the pointer is never owned at this point. I say this point, because the alternative codepath, RuntimeDyldMachO::createObjectFile certainly does take ownership, so this seemed like a good hint that this was a/the right place to take ownership. llvm-svn: 207580

* [ExecutionEngine] Allow JIT clients to enable/disable module verification.Lang Hames2014-04-181-1/+2
| | | | | | | | | | | | Previously module verification was always enabled, with no way to turn it off. As of this commit, module verification is on by default in Debug builds, and off by default in release builds. The default behaviour can be overridden by calling setVerifyModules(bool) on the JIT instance (this works for both the old JIT, and MCJIT). <rdar://problem/16150008> llvm-svn: 206561

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-5/+5
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

* Use DataLayout from the module when easily available.Rafael Espindola2014-02-251-1/+2
| | | | | | | | | | | | | | | | | Eventually DataLayoutPass should go away, but for now that is the only easy way to get a DataLayout in some APIs. This patch only changes the ones that have easy access to a Module. One interesting issue with sometimes using DataLayoutPass and sometimes fetching it from the Module is that we have to make sure they are equivalent. We can get most of the way there by always constructing the pass with a Module. In fact, the pass could be changed to point to an external DataLayout instead of owning one to make this stricter. Unfortunately, the C api passes a DataLayout, so it has to be up to the caller to make sure the pass and the module are in sync. llvm-svn: 202204
* Make DataLayout a plain object, not a pass.Rafael Espindola2014-02-251-1/+1
| | | | | | | Instead, have a DataLayoutPass that holds one. This will allow parts of LLVM don't don't handle passes to also use DataLayout. llvm-svn: 202168
* move getNameWithPrefix and getSymbol to TargetMachine.Rafael Espindola2014-02-191-1/+1
| | | | | | | | | | TargetLoweringBase is implemented in CodeGen, so before this patch we had a dependency fom Target to CodeGen. This would show up as a link failure of llvm-stress when building with -DBUILD_SHARED_LIBS=ON. This fixes pr18900. llvm-svn: 201711
* Add back r201608, r201622, r201624 and r201625Rafael Espindola2014-02-191-1/+2
| | | | | | | | | | | | | | r201608 made llvm corretly handle private globals with MachO. r201622 fixed a bug in it and r201624 and r201625 were changes for using private linkage, assuming that llvm would do the right thing. They all got reverted because r201608 introduced a crash in LTO. This patch includes a fix for that. The issue was that TargetLoweringObjectFile now has to be initialized before we can mangle names of private globals. This is trivially true during the normal codegen pipeline (the asm printer does it), but LTO has to do it manually. llvm-svn: 201700

* Fix PR18743.Rafael Espindola2014-02-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | The IR @foo = private constant i32 42 is valid, but before this patch we would produce an invalid MachO from it. It was invalid because it would use an L label in a section where the liker needs the labels in order to atomize it. One way of fixing it would be to just reject this IR in the backend, but that would not be very front end friendly. What this patch does is use an 'l' prefix in sections that we know the linker requires symbols for atomizing them. This allows frontends to just use private and not worry about which sections they go to or how the linker handles them. One small issue with this strategy is that now a symbol name depends on the section, which is not available before codegen. This is not a problem in practice. The reason is that it only happens with private linkage, which will be ignored by the non codegen users (llvm-nm and llvm-ar). llvm-svn: 201608

* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-031-2/+2
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. llvm-svn: 198438

* Remove the isImplicitlyPrivate argument of getNameWithPrefix.Rafael Espindola2013-12-051-1/+1
| | | | | | | | | | | | getSymbolWithGlobalValueBase use is to create a name of a new symbol based on the name of an existing GV. Assert that and then remove the last call to pass true to isImplicitlyPrivate. This gives the mangler API a 1:1 mapping from GV to names, which is what we need to drop the mangler dependency on the target (and use an extended datalayout instead). llvm-svn: 196472
