2003-07-21Added code that checks to see if a global variable is external before replacingJohn Criswell
a load of the global variable with the variable's constant value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7216 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7201 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-17Dinakar and I fixed a bug where we were trying to get the initializer ofJohn Criswell
an external constant. Since external constants don't have initializers, we were failing on an assert() call in llvm/GlobalVariable.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7193 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-11Trace loads and stores as they happen (stores were beingVikram S. Adve
remembered in valuesStoredInFunction, but never traced at function return, and that's too late to be finding the error anyway). Stores trace both the value and the address being stored to, but after some experience I think only values should be traced. The pointer hash table just fills up far too quickly if every store address were traced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7169 91177308-0d34-0410-b5e6-96231b3b80d8

gross, but until DSA is working all of the time and is totally reliable, we do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6917 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-24Do not mark ALL terminators live if any instruciton in the block is live. ↵Chris Lattner
We only want to mark it live if it is an unconditional branch. This fixes bug: ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6887 91177308-0d34-0410-b5e6-96231b3b80d8
