a388ca19ee fix build for GCC 4.3
Note that this requires removing the -Wconversion flag for now.  I'll
see about restoring it when I'm ready to tackle all those warnings.

ee60d48cfe fix subtle bug in hashMapInsert which caused us to update the old array previously associated with the hash map, whereas a GC causes the table to be resized when a weak reference is removed and thus a new array used 2008-01-19 13:12:16 -07:00

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.
