| | | | | | | | | | AND. This is speedup on any reasonable target, but particularly on 32-bit targets where this often turns into a libcall like udivdi3. We know that alignments are a power of two but the compiler doesn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60688 91177308-0d34-0410-b5e6-96231b3b80d8

* Generalize bugpoint's concept of a "safe" backend, and add optionsDan Gohman2008-12-085-63/+155
| | | | | | | | | | | | | | | to allow the "safe" backend to be run with a different path, and/or with different command-line options. This enables the following use cases: - bugpoint llc against an llc command from a different build - bugpoint llc against the same llc with different command-line options - and more... Also, document the existing "custom" interpreter options. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60681 91177308-0d34-0410-b5e6-96231b3b80d8

* Use intptr_t instead of unsigned here, which is more appropriateDan Gohman2008-12-071-1/+1

* Enable the Clang plugin by default.Mikhail Glushenkov2008-12-071-1/+1
| | | | | | | This will eventually replace `ccc`. The command `llvmc -clang` now uses the Clang toolchain instead of `llvm-gcc`. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60661 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a new MemDep::getNonLocalPointerDependencyChris Lattner2008-12-072-13/+94
| | | | | | | | | | method. This will eventually take over load/store dep queries from getNonLocalDependency. For now it works fine, but is incredibly slow because it does no caching. Lets not switch GVN to use it until that is fixed :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60649 91177308-0d34-0410-b5e6-96231b3b80d8
