2011-07-18indvars: LinearFunctionTestReplace for non-canonical IVs.Andrew Trick
For -disable-iv-rewrite, perform LFTR without generating a new "canonical" induction variable. Instead find the "best" existing induction variable for use in the loop exit test and compute the final value of that IV for use in the new loop exit test. In short, convert to a simple eq/ne exit test as long as it's cheap to do so. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135420 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-12indvars: Code reorganization in preparation forAndrew Trick
LinearFunctionTestReplace rewrite. No functionality. I've been wanting to group the indvar subphases into sections and order them by their logical sequence. My next checkin adds functions related to LFTR, and doing the reorg now should help reviewers. Since, most of the code in IndVarSimplify.cpp has recently been replaced or will be replaced soon, obscuring blame should not be an issue. This seems like an ideal time to shuffle the code around. I'm happy to take more suggestions for cleaning up the code. Or if you've been wanting to cleanup anything in this file yourself, now is a good time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134941 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8
