2013-05-04Fix a performance bug in the Linker.Rafael Espindola
Now that we hava a convinient place to keep it, remeber the set of identified structs as we merge modules. This speeds up the linking of all the bitcode files in clang with the gold plugin and -plugin-opt=emit-llvm (i.e., link only, no codegen) from 5:25 minutes to 13.6 seconds! Patch by Xiaofei Wan! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181104 91177308-0d34-0410-b5e6-96231b3b80d8

2013-05-01This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo
the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-11Replace DepLibs bitcode record with metadataDerek Schuff
It keeps the same Module interface as the existing/old deplibs feature, but populates the library list from the metadata after reading the bitcode/LL into the Module. Keeping the same module interface will allow us to keep the existing uses (e.g. in the gold plugin) as they are. Internally it still uses the LibraryList variable, but uses it basically as a cache backed by the metadata. BUG= Review URL: https://codereview.chromium.org/11615013

2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-03Move the "findUsedStructTypes" functionality outside of the Module class.Bill Wendling
The "findUsedStructTypes" method is very expensive to run. It needs to be optimized so that LTO can run faster. Splitting this method out of the Module class will help this occur.

2012-06-23Extend the IL for selecting TLS models (PR9788)Hans Wennborg
This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-23It's possible for two types, which are isomorphic, to be added to theBill Wendling
destination module, but one of them isn't used in the destination module. If another module comes along and the uses the unused type, there could be type conflicts when the modules are finally linked together. (This happened when building LLVM.) The test that was reduced is: Module A: %Z = type { %A } %A = type { %B.1, [7 x x86_fp80] } %B.1 = type { %C } %C = type { i8* } declare void @func_x(%C*, i64, i64) declare void @func_z(%Z* nocapture) Module B: %B = type { %C.1 } %C.1 = type { i8* } %A.2 = type { %B.3, [5 x x86_fp80] } %B.3 = type { %C.1 } define void @func_z() { %x = alloca %A.2, align 16 %y = getelementptr inbounds %A.2* %x, i64 0, i32 0, i32 0 call void @func_x(%C.1* %y, i64 37, i64 927) nounwind ret void } declare void @func_x(%C.1*, i64, i64) declare void @func_y(%B* nocapture) (Unfortunately, this test doesn't fail under llvm-link, only during an LTO linking.) The '%C' and '%C.1' clash. The destination module gets the '%C' declaration. When merging Module B, it looks at the '%C.1' subtype of the '%B' structure. It adds that in, because that's cool. And when '%B.3' is processed, it uses the '%C.1'. But the '%B' has used '%C' and we prefer to use '%C'. So the '@func_x' type is changed to 'void (%C*, i64, i64)', but the type of '%x' in '@func_z' remains '%A.2'. The GEP resolves to a '%C.1', which conflicts with the '@func_x' signature. We can resolve this situation by making sure that the type is used in the destination before saying that it should be used in the module being merged in. With this fix, LLVM and Clang both compile under LTO. <rdar://problem/10913281> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153351 91177308-0d34-0410-b5e6-96231b3b80d8
