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

2012-04-10The MDString class stored a StringRef to the string which was already in aBill Wendling
StringMap. This was redundant and unnecessarily bloated the MDString class. Because the MDString class is a "Value" and will never have a "name", and because the Name field in the Value class is a pointer to a StringMap entry, we repurpose the Name field for an MDString. It stores the StringMap entry in the Name field, and uses the normal methods to get the string (name) back.

2012-03-14Extend the inline cost calculation to account for bonuses due toChandler Carruth
correlated pairs of pointer arguments at the callsite. This is designed to recognize the common C++ idiom of begin/end pointer pairs when the end pointer is a constant offset from the begin pointer. With the C-based idiom of a pointer and size, the inline cost saw the constant size calculation, and this provides the same level of information for begin/end pairs. In order to propagate this information we have to search for candidate operations on a pair of pointer function arguments (or derived from them) which would be simplified if the pointers had a known constant offset. Then the callsite analysis looks for such pointer pairs in the argument list, and applies the appropriate bonus. This helps LLVM detect that half of bounds-checked STL algorithms (such as hash_combine_range, and some hybrid sort implementations) disappear when inlined with a constant size input. However, it's not a complete fix due the inaccuracy of our cost metric for constants in general. I'm looking into that next. Benchmarks showed no significant code size change, and very minor performance changes. However, specific code such as hashing is showing significantly cleaner inlining decisions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152752 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

2010-01-25Change Value::getUnderlyingObject to have the MaxLookup value specified as aBob Wilson
parameter with a default value, instead of just hardcoding it in the implementation. The limit of MaxLookup = 6 was introduced in r69151 to fix a performance problem with O(n^2) behavior in instcombine, but the scalarrepl pass is relying on getUnderlyingObject to go all the way back to an AllocaInst. Making the limit part of the method signature makes it clear that by default the result is limited and should help avoid similar problems in the future. This fixes pr6126. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94433 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
2009-12-28This is a major cleanup of the instruction metadata interfaces thatChris Lattner
I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-13Move the FixedStackPseudoSourceValueVal enum value before InstructionValDan Gohman

2009-09-15When a constant's type is refined, update the constant in placeDan Gohman
instead of cloning and RAUWing it. - Make AbstractTypeUser a friend of Value so that it can offer its subclasses a way to update a Value's type in place. This is better than a universally visible setType method on Value, and it's sufficient for the immediate need. - Eliminate the constant "convert" functions. This eliminates a lot of logic duplication, and fixes a complicated bug where a constant can't actually be cloned during the type refinement process because some of the types that its folder needs are half-destroyed, being in the middle of refinement themselves. - Move the getValType functions from being static overloaded functions in Constants.cpp to be members of class template specializations in ConstantsContext.h. This means that the code ends up getting instantiated twice, however it also makes it possible to eliminate all "convert" functions, so it's not a big net code size increase. And if desired, the duplicate instantiations could be eliminated with some reorganization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81861 91177308-0d34-0410-b5e6-96231b3b80d8
