* This fixes PR531, a crash when running the CBE on a bytecode file.Chris Lattner2005-03-062-4/+50
| | | | | | | | | | | | | | | | | | | The problem is that Function::renameLocalSymbols is iterating through the symbol table planes, occasionally calling setName to rename a value (which used to do a symbol table remove/insert pair). The problem is that if there is only a single value in a particular type plane that the remove will nuke the symbol table plane, and the insert will create and insert a new one. This hoses Function::renameLocalSymbols because it has an iterator to the old plane, under the (very reasonable) assumption that simply renaming a value won't cause the type plane to disappear. This patch fixes the bug by making the rename operation a single atomic operation, which has a side effect of making the whole thing faster too. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20469 91177308-0d34-0410-b5e6-96231b3b80d8
