* Create the new linker type "linker_private_weak_def_auto".Bill Wendling2010-08-201-0/+10
| | | | | | | | | | | | | It's similar to "linker_private_weak", but it's known that the address of the object is not taken. For instance, functions that had an inline definition, but the compiler decided not to inline it. Note, unlike linker_private and linker_private_weak, linker_private_weak_def_auto may have only default visibility. The symbols are removed by the linker from the final linked image (executable or dynamic library). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111684 91177308-0d34-0410-b5e6-96231b3b80d8

* re-commit r109220, the compile error has already been fixedGabor Greif2010-07-261-0/+5
| | | | | | | | | | | | | | | | Simplifying use_iterators by dereferencing is not a good idea. The codebase does not depend in this any more, and it may introduce hidden runtime cost. If you get compile errors, please dereference your iterator before passing to cast<> (and friends). Also: please consider caching the result of operator* and reusing that instead of dereferencing many times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109425 91177308-0d34-0410-b5e6-96231b3b80d8

* Add new RegionInfo pass.Tobias Grosser2010-07-221-0/+12

Furthermore an hierarchical region tree is built.

* Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"Duncan Sands2010-07-072-7/+7
| | | | | | | | | | | | | | builds to "Release". The default build is unchanged (optimization on, assertions on), however it is now called Release+Asserts. The intent is that future LLVM releases released via llvm.org will be Release builds in the new sense, i.e. will have assertions disabled (currently they have assertions enabled, for a more than 20% slowdown). This will bring them in line with MacOS releases, which ship with assertions disabled. It also means that "Release" now means the same things in make and cmake builds: cmake already disables assertions for "Release" builds AFAICS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107758 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | the noalias argument on function attributes be usable to model the C99 restrict keyword on arguments, and to allow AliasAnalysis to consider a noalias-attributed argument to be an "identified object". To support this, refactor a new "based on" concept out of the current pointer aliasing "associated" concept. This "based on" concept is very similar to (though it is not identical with) the "based on" concept in C99. Also, reword the definition of NoAlias to more closely describe the concept that the optimizer uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107495 91177308-0d34-0410-b5e6-96231b3b80d8
