2004-07-20Rewrite cast->cast elimination code completely based on the information weChris Lattner
actually care about. Someday when the cast instruction is gone, we can do better here, but this will do for now. This implements instcombine/cast.ll:test17/18 as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15018 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-19Added support for stdint.h. It is now automatically included byJohn Criswell
DataTypes.h. So far, it doesn't seem to break Linux, Solaris, or MacOS X. This should automatically include it for those people who need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15006 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-19When joining intervals, join intervals in deeply nested loops first. ThisChris Lattner
is a simple change, but seems to improve code a little. For example, on 256.bzip2, we went from 75.0s -> 73.33s (2% speedup). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15004 91177308-0d34-0410-b5e6-96231b3b80d8

Patch contributed by the fabulous Nate Begeman. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14994 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-19Two changes, both very significant:Chris Lattner
* vreg <-> vreg joining now works, enable it unconditionally when joining is enabled (which is the default). * Fix a serious pessimization of spill code where we were saying that a spilled DEF operand was live into the subsequent instruction. This allows for substantially better code when spilling starts to happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14993 91177308-0d34-0410-b5e6-96231b3b80d8
