* (1) Change the way unused regs. are marked and found to consider regTypeVikram S. Adve2003-07-251-24/+24
| | | | | | | | | | | info (since multiple reg types may share the same reg class). (2) Remove machine-specific regalloc. methods that are no longer needed. In particular, arguments and return value from a call do not need machine-specific code for allocation. (3) Rename TargetRegInfo::getRegType variants to avoid unintentional overloading when an include file is omitted. llvm-svn: 7329

* Numerous bug fixes:Vikram S. Adve2002-05-191-0/+16
| | | | | | | | | | | | | | | | | | | -- 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 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 llvm-svn: 2642
