* [Modules] Move InstIterator out of the Support library, where it had noChandler Carruth2014-03-04
| | | | | | | | | | | | | business. This header includes Function and BasicBlock and directly uses the interfaces of both classes. It has to do with the IR, it even has that in the name. =] Put it in the library it belongs to. This is one step toward making LLVM's Support library survive a C++ modules bootstrap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202814 91177308-0d34-0410-b5e6-96231b3b80d8
* Put the functionality for printing a value to a raw_ostream as anChandler Carruth2014-01-09
| | | | | | | | | | | | operand into the Value interface just like the core print method is. That gives a more conistent organization to the IR printing interfaces -- they are all attached to the IR objects themselves. Also, update all the users. This removes the 'Writer.h' header which contained only a single function declaration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198836 91177308-0d34-0410-b5e6-96231b3b80d8
* Move the LLVM IR asm writer header files into the IR directory, as theyChandler Carruth2014-01-07
| | | | | | | | | | | | | | | | | are part of the core IR library in order to support dumping and other basic functionality. Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198688 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | 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
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | 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

* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-19
| | | | | | | | | | | | | | | | | | exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8
