-- correct sign extensions for integer casts and for shift-by-constant instructions generated for integer multiply -- passing FP arguments to functions with more than 6 arguments -- passing FP arguments to varargs functions -- passing FP arguments to functions with no prototypes -- incorrect stack frame size when padding a section -- folding getelementptr operations with mixed array and struct indexes -- use uint64_t instead of uint for constant offsets in mem operands -- incorrect coloring for CC registers (both int and FP): interferences were being completely ignored for int CC and were considered but no spills were marked for fp CC! Also some code improvements: -- better interface to generating machine instr for common cases (many places still need to be updated to use this interface) -- annotations on MachineInstr to communicate information from one codegen phase to another (now used to pass information about CALL/JMPLCALL operands from selection to register allocation) -- all sizes and offests in class TargetData are uint64_t instead of uint git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2640 91177308-0d34-0410-b5e6-96231b3b80d8
