llvm/test/Transforms/ConstProp, branch release_30 http://llvm.org https://git.amat.us/llvm/atom/test/Transforms/ConstProp?h=release_30 2011-07-09T17:41:24Z Land the long talked about "type system rewrite" patch. This 2011-07-09T17:41:24Z Chris Lattner sabre@nondot.org 2011-07-09T17:41:24Z urn:sha1:1afcace3a3a138b1b18e5c6270caa8dae2261ae2 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 implement PR9315, constant folding exp2 in terms of pow (since hosts without 2011-05-22T22:22:35Z Chris Lattner sabre@nondot.org 2011-05-22T22:22:35Z urn:sha1:805fa97a0f5ff61624855da37d4881708fb8f0fb C99 runtimes don't have exp2). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131872 91177308-0d34-0410-b5e6-96231b3b80d8 Fix a ton of comment typos found by codespell.
