2007-10-17Updated VC++ build system.Hartmut Kaiser
Silenced some VC warnings.

2007-07-11Add FastDSE, a new algorithm for doing dead store elimination. This ↵Owen Anderson
algorithm is not as accurate as the current DSE, but it only a linear scan over each block, rather than quadratic. Eventually (once it has been improved somewhat), this will replace the current DSE.

2007-05-02Use 'static const char' instead of 'static const int'.Devang Patel
Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36652 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-15For PR1195:Reid Spencer
Rename PackedType -> VectorType, ConstantPacked -> ConstantVector, and PackedTyID -> VectorTyID. No functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34293 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-05For PR411:Reid Spencer
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
