* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-092-89/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Fix a subtle issue in SmallVector. The following code did not work as expected:Owen Anderson2011-07-061-21/+27
| | | | | | | | | | vec.insert(vec.begin(), vec[3]); The issue was that vec[3] returns a reference into the vector, which is invalidated when insert() memmove's the elements down to make space. The method needs to specifically detect and handle this case to correctly match std::vector's semantics. Thanks to Howard Hinnant for clarifying the correct behavior, and explaining how std::vector solves this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134554 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | all over the place in different styles and variants. Standardize on two preferred entrypoints: one that takes a StructType and ArrayRef, and one that takes StructType and varargs. In cases where there isn't a struct type convenient, we now add a ConstantStruct::getAnon method (whose name will make more sense after a few more patches land). It would be "really really nice" if the ConstantStruct::get and ConstantVector::get methods didn't make temporary std::vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133412 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach getCastOpcode about element-by-element vector casts. For example, "trunc"Duncan Sands2011-05-181-0/+8
| | | | | | | | | | | | | | can be used to turn a <4 x i64> into a <4 x i32> but getCastOpcode would assert if you passed these types to it. Note that this strictly extends the previous functionality: if getCastOpcode previously accepted two vector types (i.e. didn't assert) then it still will and returns the same opcode (BitCast). That's because before it would only accept vectors with the same bitwidth, and the new code only touches vectors with the same length. However if two vectors have both the same bitwidth and the same length then their element types have the same bitwidth, so the new logic will return BitCast as before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131530 91177308-0d34-0410-b5e6-96231b3b80d8

* Add APFloat::getExactInverse.Benjamin Kramer2011-03-301-0/+23
| | | | | | | | | | | | | | The idea is, that if an ieee 754 float is divided by a power of two, we can turn the division into a cheaper multiplication. This function sees if we can get an exact multiplicative inverse for a divisor and returns it if possible. This is the hard part of PR9587. I tested many inputs against llvm-gcc's frotend implementation of this optimization and didn't find any difference. However, floating point is the land of weird edge cases, so any review would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128545 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | Add a unnamed_addr bit to global variables and functions. This will be used to indicate that the address is not significant and therefore the constant or function can be merged with others. If an optimization pass can show that an address is not used, it can set this. Examples of things that can have this set by the FE are globals created to hold string literals and C++ constructors. Adding unnamed_addr to a non-const global should have no effect unless an optimization can transform that global into a constant. Aliases are not allowed to have unnamed_addr since I couldn't figure out any use for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123063 91177308-0d34-0410-b5e6-96231b3b80d8
