* Get rid of unused isPodLike definitions.Eli Friedman2013-09-111-10/+0

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-2/+2
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 171366
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-7/+7
| | | | | | | | | | | | | | | | | 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. =] llvm-svn: 169131

* Make MemoryBuiltins aware of TargetLibraryInfo.Benjamin Kramer2012-08-291-1/+1
| | | | | | | | | | | | | | | | This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. llvm-svn: 162841

* Fix a couple hash functions so that they do not depend on undefined shifts. ↵Eli Friedman2011-10-121-2/+2
| | | | | | Based on patch by Ahmed Charles. llvm-svn: 141820
* Change a bunch of isVolatile() checks to check for atomic load/store as well.Eli Friedman2011-09-121-2/+2
| | | | | | | | No tests; these changes aren't really interesting in the sense that the logic is the same for volatile and atomic. I believe this completes all of the changes necessary for the optimizer to handle loads and stores correctly. I'm going to try and come up with some additional testing, though. llvm-svn: 139533
* Duncan deftly points out that readnone functions aren'tChris Lattner2011-01-031-1/+5
| | | | | | | invalidated by stores, so they can be handled as 'simple' operations. llvm-svn: 122785
* stength reduce my previous patch a bit. The only instructionsChris Lattner2011-01-031-6/+9
| | | | | | | | | | | that are allowed to have metadata operands are intrinsic calls, and the only ones that take metadata currently return void. Just reject all void instructions, which should not be value numbered anyway. To future proof things, add an assert to the getHashValue impl for calls to check that metadata operands aren't present. llvm-svn: 122759
* fix PR8895: metadata operands don't have a strong use of theirChris Lattner2011-01-031-4/+10
| | | | | | | | | | nested values, so they can change and drop to null, which can change the hash and cause havok. It turns out that it isn't a good idea to value number stuff with metadata operands anyway, so... don't. llvm-svn: 122758
* earlycse can do trivial with-a-block dead store Chris Lattner2011-01-031-6/+38
| | | | | | | elimination as well. This deletes 60 stores in 176.gcc that largely come from bitfield code. llvm-svn: 122736

* Teach EarlyCSE to do trivial CSE of loads and read-only calls.Chris Lattner2011-01-031-22/+152
| | | | | | | On 176.gcc, this catches 13090 loads and calls, and increases the number of simple instructions CSE'd from 29658 to 36208. llvm-svn: 122727
