marked read-write. Use const so that they can be allocated in a read-only segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48800 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-12Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner
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

2008-01-07Enabling the target-independent garbage collection infrastructure by hooking itGordon Henriksen
up to the various compiler pipelines. This doesn't actually add support for any GC algorithms, which means it temporarily breaks a few tests. To be fixed shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45669 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-03Rather than having special rules like "intrinsics cannotDuncan Sands
throw exceptions", just mark intrinsics with the nounwind attribute. Likewise, mark intrinsics as readnone/readonly and get rid of special aliasing logic (which didn't use anything more than this anyway). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44544 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Work around a GCC bug, producing this code:Chris Lattner
unsigned char *llvm_cbe_X; ... llvm_cbe_X = 0; *((void**)&llvm_cbe_X) = __builtin_stack_save(); instead of: llvm_cbe_X = __builtin_stack_save(); See PR1809 for details. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44415 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-27Fix PR1146: parameter attributes are longer part ofDuncan Sands
the function type, instead they belong to functions and function calls. This is an updated and slightly corrected version of Reid Spencer's original patch. The only known problem is that auto-upgrading of bitcode files doesn't seem to work properly (see test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully a bitcode guru (who might that be? :) ) will fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44359 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-15Fix PR1666, SPASS with the CBE and 254.gap with the CBE.Chris Lattner
GCC optimizes away things like ptr < NULL to false. To "fix" this, have the CBE emit casts of pointers to intptr_t when doing relational pointer comparisons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41983 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-14Remove the assumption that FP's are either float orDale Johannesen
double from some of the many places in the optimizers it appears, and do something reasonable with x86 long double. Make APInt::dump() public, remove newline, use it to dump ConstantSDNode's. Allow APFloats in FoldingSet. Expand X86 backend handling of long doubles (conversions to/from int, mostly). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41967 91177308-0d34-0410-b5e6-96231b3b80d8

access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41858 91177308-0d34-0410-b5e6-96231b3b80d8
