* Now Attributes are divided in three groupsDevang Patel2008-09-262-8/+49
| | | | | | | | | | | | | | - return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index. Function attributes use ~0U as the index. This patch requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56704 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-enables the new vector select in the bitcode reader, by modifying theDan Gohman2008-09-161-5/+23
| | | | | | | | | | | | | | | | | | | | | | | bitcode reader/writer as follows: - add and use new bitcode FUNC_CODE_INST_VSELECT to handle the llvm select opcode using either i1 or [N x i1] as the selector. - retain old BITCODE FUNC_CODE_INST_SELECT in the bitcode reader to handle select on i1 for backwards compatibility with existing bitcode files. - re-enable the vector-select.ll test program. Also, rename the recently added bitcode opcode FUNC_CODE_INST_VCMP to FUNC_CODE_INST_CMP2 and make the bitcode writer use it to handle fcmp/icmp on scalars or vectors. In the bitcode writer, use FUNC_CODE_INST_CMP for vfcmp/vicmp only. In the bitcode reader, have FUNC_CODE_INST_CMP handle icmp/fcmp returning bool, for backwards compatibility with existing bitcode files.

* Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen2008-08-171-8/+8
| | | | | | | | | | | | | | | | | | 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
* Enable first-class aggregates support.Dan Gohman2008-07-231-13/+27
| | | | | | | | | | | | | Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a little wrapper header that is put around bc files when emittingChris Lattner2008-07-091-1/+51
| | | | | | | | | | | | | | | | | bc files for modules with a target triple that indicates they are for darwin. The reader unconditionally handles this, and the writer could turn this on for more targets if we care. This change has two benefits for darwin: 1) it allows us to encode the cpu type of the file in an easy to read place that doesn't require decoding the bc file. 2) it works around a bug (IMO) in darwin's AR where it is incapable of handling files that are not a multiple of 8 bytes long. BC files are only guaranteed to be multiples of 4 bytes long. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53275 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner2008-03-122-21/+10
| | | | | | | | | | | | | | | | | | | | | | | | | 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
