* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-14172-812/+813
| | | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | "$non_lazy_ptr" to symbols instead of doing it with "printSuffixedName". This gets us to the point where there is a real separation between computing a symbol name and printing it, something I need for MC printer stuff. This patch also fixes a corner case bug where unnamed private globals wouldn't get the private label prefix. Next up, rename all uses of getValueName -> getMangledName for better greppability, and then tackle the ppc/arm backends to eliminate "printSuffixedName". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75610 91177308-0d34-0410-b5e6-96231b3b80d8
* New VNInfo alignment patch by Ryan Flynn.Lang Hames2009-07-141-14/+3

* 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).
