Alex Shinn	39fdd89474	not trying to adjust the heap, just keeping a linked list ... of heap chunks. expanding the heap thus works now, so i've removed all the debugging utils from gc.c, except the conservative checks which are now a config option.	2009-06-17 22:37:21 +09:00
Alex Shinn	ba484795d1	considering adjusting heap a dead-end for now	2009-06-15 19:04:44 +09:00

Alex Shinn	bddbaedfa7	test suite now passes with new gc, even starting ... with a tiny heap and causing multiple allocations. pointer adjusting after a moved realloc still segfaults.	2009-06-13 21:16:49 +09:00

Alex Shinn	54baeaca36	don't sweep the free-list elements! ... implementing heap expansion w/ realloc. realloc is always giving back the same pointer right now, so pointer adjusting not tested yet.	2009-06-10 00:38:15 +09:00
Alex Shinn	d65e7255f8	stack is now a data type (maybe merge w/ vector), ... new gc seems initially functional	2009-06-08 02:06:24 +09:00

Alex Shinn	28d5775bbe	string and vector data is now packed, no longer allocing arbitrary ... blocks of untagged data, string and vector reads use an initial buffer to reduce allocations	2009-05-06 22:43:24 +09:00
