2002-12-10This file implements a pass that automatically parallelizes a program,Vikram S. Adve
using the Cilk multi-threaded runtime system to execute parallel code. The current version inserts too many sync() operations in the program because it does not attempt to optimize their placement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4962 91177308-0d34-0410-b5e6-96231b3b80d8

2002-12-06Two bug fixes:Vikram S. Adve
(1) Make entries for Constant values in the ScalarMap. (2) Set MOD bit for the node pointed to by the argument of a free instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4948 91177308-0d34-0410-b5e6-96231b3b80d8
2002-12-06Fix several related bugs in DSNode::mergeWith() caused by theVikram S. Adve
fact that the incoming nodes may be merged away at intermediate steps. Use an extra level of indirection via DSNodeHandles to track the nodes being merged. All this now happens in a static helper function MergeNodes(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4947 91177308-0d34-0410-b5e6-96231b3b80d8
2002-12-05Cute bug fix: when moving links from N to this, some links could haveVikram S. Adve
been missed if node *this got merged away due to recursive merging! Also, links were not moved correctly if a node is collapsed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4933 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-27Fix logical error in TD pass: we should clear Mod/Ref bits of each callerVikram S. Adve
before inlining their graphs into a function. To support this, added flags to CloneFlags to strip/keep Mod/Ref bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4836 91177308-0d34-0410-b5e6-96231b3b80d8
