* Convert RegClass::IsColorUsedArr from a dynamically allocated array toChris Lattner2002-05-231-5/+4
| | | | | | | a vector. This makes asserting on array bounds easier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2731 91177308-0d34-0410-b5e6-96231b3b80d8
* 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2642 91177308-0d34-0410-b5e6-96231b3b80d8
