* Checking in Chris's suggestions:John Criswell2003-11-041-3/+32
| | | | | | | | | | | Added assert() to ensure symbol table is well formed. Added code to remember the value that was found; resolving types can change the symbol table and invalidate the value of the iterator. Added comments to the ResolveTypes() function (mainly for my own benefit). Please feel free to correct the comments if they are not accurate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9693 91177308-0d34-0410-b5e6-96231b3b80d8

* Make this pass substantially stronger by having it delete dead return valuesChris Lattner2003-10-231-127/+354
| | | | | | | | | | as well as arguments. Now it can delete arguments and return values which are only passed into other arguments or are returned, if they are dead.
