LLVM backend for 6502

Vikram S. Adve 4cecdd206e Several fixes: ... (1) Avoid hard-coding some register numbers. (2) Fix some incorrect branch opcodes. (3) Don't try to move int register to float register! (4) If an operand being forwarded is a constant and it doesn't fit into the immed field of the copy machine instruction, then generate a load-constant instead of a copy. (5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@683 91177308-0d34-0410-b5e6-96231b3b80d8		2001-10-01 00:12:53 +00:00
