* Wrap MVT::ValueType in a struct to get type safetyDuncan Sands2008-06-061-2/+1
| | | | | | | | | | | | | | | | and better control the abstraction. Rename the type to MVT. To update out-of-tree patches, the main thing to do is to rename MVT::ValueType to MVT, and rewrite expressions like MVT::getSizeInBits(VT) in the form VT.getSizeInBits(). Use VT.getSimpleVT() to extract a MVT::SimpleValueType for use in switch statements (you will get an assert failure if VT is an extended value type - these shouldn't exist after type legalization). This results in a small speedup of codegen and no new testsuite failures (x86-64 linux). llvm-svn: 52044

* When the register allocator runs out of registers, spill a physical register ↵Evan Cheng2008-03-111-5/+6
| | | | | | around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting. llvm-svn: 48218
