2002-12-03This should fix the bug seen with some registers not being allocatedMisha Brukman
correctly: skipping instructions by incorrectly incrementing the pointer. Also adds support for building a reg-to-regclass map, and splits the function for saving register to stack into two, one suitable for virtual registers (which also assigns it a physical register) and one for simply storing back physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4898 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
2002-11-27(1) Bug fix that was causing nodes with dangling references to be freed.Vikram S. Adve
We run removeDeadNodes() on the TD graph up front before using it. (2) Major enhancement to printing of results: now we list the actual objects that are mod/ref instead of just printing the bit vectors. Also an important bug fix in TDDataStructures pass (no change here): clear Mod/Ref bits of callers before inlining into a function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4833 91177308-0d34-0410-b5e6-96231b3b80d8
