* [Modules] Fix a layering issue that is actually impacting the modulesChandler Carruth2014-03-06
| | | | | | | | | | | | | | | | | | | | | | selfhost. The 'Core.h' C-API header is part of the IR LLVM library. (One might even argue it should be called IR.h, but that's a separate point.) We can't include it into a Support header without violating the layering, and in a way that breaks modules. MemoryBuffer's opaque C type was being defined in the Core.h C-API header despite being in the Support library, and thus we ended up with this weird issue. It turns out that there were other constructs from the Support library in the Core.h header. This patch lifts all of them into Support.h and then includes that into Core.h. The only possible fallout is if someone was including Support.h and relying on Core.h to be visible for their own uses. Considering the narrow interface actually provided by the C-API for the Support library, this seems a very, very unlikely mistake. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203071 91177308-0d34-0410-b5e6-96231b3b80d8
* [C++11] Add overloads for externally used OwningPtr functions.Ahmed Charles2014-03-05
| | | | | | | | This will allow external callers of these functions to switch over time rather than forcing a breaking change all a once. These particular functions were determined by building clang/lld/lldb. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202959 91177308-0d34-0410-b5e6-96231b3b80d8

* Split getOpenFile into getOpenFile and getOpenFileSlice.Rafael Espindola2013-07-23
| | | | | | | | | | | | | | | | The main observation is that we never need both the filesize and the map size. When mapping a slice of a file, it doesn't make sense to request a null terminator and that would be the only case where the filesize would be used. There are other cleanups that should be done in this area: * A client should not have to pass the size (even an explicit -1) to say if it wants a null terminator or not, so we should probably swap the argument order. * The default should be to not require a null terminator. Very few clients require this, but many end up asking for it just because it is the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186984 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo2013-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
