* CMake: Add a new configuration option LLVM_BUILD_CLANG that'sDouglas Gregor2011-07-141-1/+4
| | | | | | | | | | | | available when Clang is found within the LLVM tree. If enabled (the default), Clang will be built as part of LLVM. If disabled, Clang will be skipped... and can be built by configuring a separate object directory just for Clang. This helps break up the monolithic LLVM+Clang project that many Clang developers use, improving build/load times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135218 91177308-0d34-0410-b5e6-96231b3b80d8

* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-093-23/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Change createAsmParser to take a MCSubtargetInfo instead of triple,Evan Cheng2011-07-093-6/+13
| | | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134795 91177308-0d34-0410-b5e6-96231b3b80d8
* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-082-2/+6
| | | | | | | | | | | - Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134678 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LSDA is a bit difficult for the non-initiated to read.
