# R.Hanai
#
# Compile options:
#
# * How to scan stacks
# __RETURN_BARRIER: scan stacks incrementally.
# not defined:
#
# * How to stop mutators - any of the next must be specified.
# __USE_POLLING: polling
# __USE_SIGNAL: signal (not implemented)
#
# * How to proceed GC work - any of the next must be specified.
# __GC_ALLOC_DRIVEN:
# __GC_SEPARATE_THREAD:
# __GC_HYBRID: (not yet implemented)
#
# * Mark bits
# __USE_MARK_BITMAP: mark bits are prepared as byte maps, not in object headers.
# not defined: (not implemented correctly)
#
# * Heap expansion
# __HEAP_EXPANDABLE: expandable-heap.
# not defined:
#
# * Other options
#
# __DEBUG: print detailed gc information.
