Chandler Carruth 11c412fd2c Teach LLVM about a PIE option which, when enabled on top of PIC, makes ... optimizations which are valid for position independent code being linked into a single executable, but not for such code being linked into a shared library. I discussed the design of this with Eric Christopher, and the decision was to support an optional bit rather than a completely separate relocation model. Fundamentally, this is still PIC relocation, its just that certain optimizations are only valid under a PIC relocation model when the resulting code won't be in a shared library. The simplest path to here is to expose a single bit option in the TargetOptions. If folks have different/better designs, I'm all ears. =] I've included the first optimization based upon this: changing TLS models to the *Exec models when PIE is enabled. This is the LLVM component of PR12380 and is all of the hard work. llvm-svn: 154294		2012-04-08 17:51:45 +00:00

Generic	Add VSELECT to LegalizeVectorTypes::ScalariseVectorResult. Previously it would crash if it encountered a 1 element VSELECT. Solution is slightly more complicated than just creating a SELET as we have to mask or sign extend the vector condition if it had different boolean contents from the scalar condition.
