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

AttributeSet accessor method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171256 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-30Remove Function::getParamAttributes and use the AttributeSet accessor ↵Bill Wendling
methods instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171255 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-30Remove the Function::getFnAttributes method in favor of using the AttributeSetBill Wendling
directly. This is in preparation for removing the use of the 'Attribute' class as a collection of attributes. That will shift to the AttributeSet class instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171253 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-22Change 'AttrVal' to 'AttrKind' to better reflect that it's a kind of ↵Bill Wendling
attribute instead of the value of the attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170972 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Add a new attribute, 'noduplicate'. If a function contains a noduplicate ↵James Molloy
call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call. Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170704 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Refactor isIntrinsic() to be quicker, and change classof() (and thus, ↵Michael Ilseman
isa<IntrinsicInst>()) to use it. This decreases the number of occurrences of the slow-path string matching performed by getIntrinsicID(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170602 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-19Rename the 'Attributes' class to 'Attribute'. It's going to represent a ↵Bill Wendling
single attribute in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170502 91177308-0d34-0410-b5e6-96231b3b80d8

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

2012-10-15Move the Attributes::Builder outside of the Attributes class and into its ↵Bill Wendling
own class named AttrBuilder. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165960 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-15Attributes RewriteBill Wendling
Convert the internal representation of the Attributes class into a pointer to an opaque object that's uniqued by and stored in the LLVMContext object. The Attributes class then becomes a thin wrapper around this opaque object. Eventually, the internal representation will be expanded to include attributes that represent code generation options, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165917 91177308-0d34-0410-b5e6-96231b3b80d8

enums. These are then created via the correct Attributes creation method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165607 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-10Have 'addFnAttr' take the attribute enum value. Then have it build the ↵Bill Wendling
attribute object and add it appropriately. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165595 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-09Create enums for the different attributes.Bill Wendling
We use the enums to query whether an Attributes object has that attribute. The opaque layer is responsible for knowing where that specific attribute is stored. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165488 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Buildbot Fix.Bill Wendling
This method can be called with a '0' argument which checks the return value. However, the method it calls doesn't expect '0' as a valid value. Call the correct method when it's 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164735 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Remove the `hasFnAttr' method from Function.Bill Wendling
The hasFnAttr method has been replaced by querying the Attributes explicitly. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164725 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-20Refactor code from inlining and globalopt that checks whether a function ↵Eli Friedman
definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142572 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-17Correct over-zealous removal of hack.Bill Wendling
Some code want to check that *any* call within a function has the 'returns twice' attribute, not just that the current function has one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142221 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Fix some issues Duncan found in the previous commit.Rafael Espindola
I kept the reference to the ABI since that is the common case. The -fno-asynchronous-unwind-tables option is a user controlled way of breaking the ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132053 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Replace the -unwind-tables option with a per function flag. This is moreRafael Espindola

2010-03-24Finally land the InvokeInst operand reordering.Gabor Greif
I have audited all getOperandNo calls now, fixing hidden assumptions. CallSite related uglyness will be eliminated successively. Note this patch has a long and griveous history, for all the back-and-forths have a look at CallSite.h's log. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99399 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-29add a layer of accessors around the Value::SubClassData member, and use Chris Lattner
a convention (shadowing the setter with private forwarding function) to prevent subclasses from accidentally using it. This exposed some bogosity in ConstantExprs, which was propaging the opcode of the constant expr into the NUW/NSW/Exact field in the getWithOperands/getWithOperandReplaced methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92239 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-15mark getIntrinsicID() 'readonly'. This allows various classof methods Chris Lattner
(like DbgDeclareInst's) to shrink substantially. It sucks that we have to pull Compiler.h into such a public header, but at least Compiler.h doesn't pull anything else in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88863 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25re-committing yesterday's r79938.Gabor Greif
This time there is no additional include of llvm/Config/config.h at all.

2009-08-24Resubmit an earlier patch of mine:Gabor Greif
reduce the size of relevant "ghostly" sentinels by a pointer. This attempt now makes the compactification dependent on the configure variable LLVM_COMPACT_SENTINELS and should not cause any bootstrap failures for llvm-gcc any more. Please note that this is not yet the final version, and (as settled with Chris) I shall take out the autofoo/cmake portions in the next days. This will also lose the assertability on sentinel dereferencing and operator++, but that seems an acceptable price to pay for the simplified build logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79938 91177308-0d34-0410-b5e6-96231b3b80d8
