* For PR411:Reid Spencer2007-02-051-6/+9
| | | | | | | | | | | This patch replaces the SymbolTable class with ValueSymbolTable which does not support types planes. This means that all symbol names in LLVM must now be unique. The patch addresses the necessary changes to deal with this and removes code no longer needed as a result. This completes the bulk of the changes for this PR. Some cleanup patches will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33918 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR411:Reid Spencer2007-01-061-4/+4
| | | | | | | | | | Take an incremental step towards type plane elimination. This change separates types from values in the symbol tables by finally making use of the TypeSymbolTable class. This yields more natural interfaces for dealing with types and unclutters the SymbolTable class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32956 91177308-0d34-0410-b5e6-96231b3b80d8

* This fixes PR531, a crash when running the CBE on a bytecode file.Chris Lattner2005-03-061-4/+14
| | | | | | | | | | | | | | | | | | | 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
