2012-12-03Sort the #include lines for the include/... tree with the script.Chandler Carruth
AKA: Recompile *ALL* the source code! This one went much better. No manual edits here. I spot-checked for silliness and grep-checked for really broken edits and everything seemed good. It all still compiles. Yell if you see something that looks goofy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169133 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Teach the include sorter to not choke on include guards. ;]Chandler Carruth
Kind of important when prepping the include/... tree version of the sort changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169132 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

2012-12-03Add a completely hack-ish tool to sort includes according to the codingChandler Carruth
standards. I am a terrible Python programmer. Patches more the welcome. Please tell me how this should look if it should look differently. It's just a tiny little script so it didn't make sense to go through pre-commit review, especially as someone who actually knows python may want to just rip it apart and do it The Right Way. I will be preparing a commit shortly that uses this script to canonicalize *all* of the #include lines in LLVM. Really, all of them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169125 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-03Remove some buggy and apparantly unnecessary code from SROA.Chandler Carruth
The partitioning logic attempted to handle uses of an alloca with an offset starting before the alloca so long as the use had some overlap with the alloca itself. However, there was a bug where we tested '(uint64_t)Offset >= AllocSize' without first checking whether 'Offset' was positive. As a consequence, essentially every negative offset (that is, starting *before* the alloca does) would be thrown out, even if it was overlapping. The subsequent code to throw out negative offsets which were actually non-overlapping was essentially dead. The code to *handle* overlapping negative offsets was actually dead! I've just removed all of this, and taught SROA to discard any uses which start prior to the alloca from the beginning. It has the lovely property of simplifying the code. =] All the tests still pass, and in fact no new tests are needed as this is already covered by our testsuite. Fixing the code so that negative offsets work the way the comments indicate they were supposed to work causes regressions. That's how I found this. Anyways, this is all progress in the correct direction -- tightening up SROA to be maximally aggressive. Some day, I really hope to turn out-of-bounds accesses to an alloca into 'unreachable'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169120 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-02Fix a bug in FileCheck that wouldn't let define variables as follows:Eli Bendersky
; CHECK: [[VAR:[a-z]]] The problem was that to find the end of the regex var definition, it was simplistically looking for the next ]] and finding the incorrect one. A better approach is to count nesting of brackets (taking escaping into account). This way the brackets that are part of the regex can be discovered and skipped properly, and the ]] ending is detected in the right place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169109 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-01The patch is to improve the memory footprint of pass GlobalOpt. Zhou Sheng
Also check in a case to repeat the issue, on which 'opt -globalopt' consumes 1.6GB memory. The big memory footprint cause is that current GlobalOpt one by one hoists and stores the leaf element constant into the global array, in each iteration, it recreates the global array initializer constant and leave the old initializer alone. This may result in many obsolete constants left. For example: we have global array @rom = global [16 x i32] zeroinitializer After the first element value is hoisted and installed: @rom = global [16 x i32] [ 1, 0, 0, ... ] After the second element value is installed: @rom = global [16 x 32] [ 1, 2, 0, 0, ... ] // here the previous initializer is obsolete ... When the transform is done, we have 15 obsolete initializers left useless. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169079 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-01Simplify REG_SEQUENCE lowering.Jakob Stoklund Olesen
The TwoAddressInstructionPass takes the machine code out of SSA form by expanding REG_SEQUENCE instructions into copies. It is no longer necessary to rewrite the registers used by a REG_SEQUENCE instruction because the new coalescer algorithm can do it now. REG_SEQUENCE is just converted to a sequence of sub-register copies now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169067 91177308-0d34-0410-b5e6-96231b3b80d8

MachineCopyPropagation doesn't understand super-register liveness well enough to be able to remove implicit defs of super-registers.
