* Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want toBill Wendling2009-04-282-2/+3
| | | | | | | | | | | | use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'm not 100% sure if it's necessary to change it there... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70270 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen2008-08-171-1/+1
| | | | | | | | | | | | | | | | | | In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54899 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement CBE support for first-class structs and array values,Dan Gohman2008-06-021-18/+77
| | | | | | | | | | | | | | | | and insertvalue and extractvalue instructions. First-class array values are not trivial because C doesn't support them. The approach I took here is to wrap all arrays in structs. Feedback is welcome. The 2007-01-15-NamedArrayType.ll test needed to be modified because it has a "not grep" for a string that now exists, because array types now have associated struct types, and those struct types have names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51881 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix the CBE's handling of instructions whose result is an i1. Previously,Chris Lattner2008-05-311-20/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | we did not truncate the value down to i1 with (x&1). This caused a problem when the computation of x was nontrivial, for example, "add i1 1, 1" would return 2 instead of 0. This makes the testcase compile into: ... llvm_cbe_t = (((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u))&1); llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t)); ... instead of: ... llvm_cbe_t = ((llvm_cbe_r == 0u) + (llvm_cbe_r == 0u)); llvm_cbe_u = (((unsigned int )(bool )llvm_cbe_t)); ...

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-121-20/+19
| | | | | | | | | | | | | | | | | | | | | | | | | 1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8
