* Be more precise about which conversions of NaNsDale Johannesen2008-10-063-3/+49
| | | | | | | | | | are Inexact. (These are not Inexact as defined by IEEE754, but that seems like a reasonable way to abstract what happens: information is lost.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57218 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow scalarrepl to treat an all-zero GEP just as bitcast.Matthijs Kooijman2008-10-062-14/+52
| | | | | | | | This includes not marking a GEP involving a vector as unsafe, but only when it has all zero indices. This allows scalarrepl to work in a few more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57177 91177308-0d34-0410-b5e6-96231b3b80d8
* Actually run Obj-C++ tests if llvm-gcc supports.Duncan Sands2008-10-063-3/+3
| | | | | | | | | | | | Before there were two problems: (1) configure turned "obj-c++" into "obj" in the langs line; (2) the dejagnu library called it objc++ not obj-c++.
