Joel Dice	a17cbf2880	fix reversed operand encoding for shift instructions	2008-01-10 14:56:08 -07:00
Joel Dice	4c938d496e	fix 64-bit bitshifts on 32-bit systems	2008-01-10 13:47:55 -07:00
Joel Dice	15f627701b	fix thinko in 8-byte shift operation implementations	2008-01-10 11:38:25 -07:00
Joel Dice	8e5ce11047	refactor memory management code ... We now support immortal objects, which the GC will scan for references but not consider for collection. On x86_64, we allocate JIT code memory via mmap, which lets us map memory into the bottom 2GB of the address space, ensuring that 32-bit relative jumps and calls work.	2008-01-09 18:20:36 -07:00
