* New VNInfo alignment patch by Ryan Flynn.Lang Hames2009-07-141-14/+3
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75609 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the internal interface to makeNameProper to take a bool thatChris Lattner2009-07-146-46/+31
| | | | | | | | | | | | | | indicates whether the label is private or not, instead of taking prefix stuff. One effect of this is that symbols will be generated with *just* the private prefix, instead of both the private prefix *and* the user-label-prefix, but this doesn't matter as long as it is consistent. For example we'll now get "Lfoo" instead of "L_foo". These are just assembler temporary labels anyway, so they never even make it into the .o file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75607 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a new LoopInfo utility function makeLoopInvariant, whichDan Gohman2009-07-142-1/+89
| | | | | | | | | | | | works similar to isLoopInvariant, except that it will do trivial hoisting to try to make the value loop invariant if it isn't already. This makes it easier for transformation passes to clear trivial instructions out of the way (the regular LICM pass doesn't run until relatively late). This is code factored out of LoopSimplify and other places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75578 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | descriptive. Thange them to keep track of the ID of a global that is assigned, not the first mangled name returned for it. Without doing this, we are required to always use the same suffix for a global that gets mangled. This means that we can mangle the same global once with $stub and another time with $non_lazy_ptr or whatever. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75561 91177308-0d34-0410-b5e6-96231b3b80d8

* Two changes:Chris Lattner2009-07-132-11/+3
| | | | | | | | | | | | 1) unique globals with the existing "Count" local in Mangler, not with atomic nonsense. Using atomics will give us nondeterminstic output from the compiler when using multiple threads, which is bad. 2) Do not mangle an unknown global name with a type suffix.
