Alex Shinn	24d9bfc950	switching to linking as a library	2009-06-20 21:57:28 +09:00
Alex Shinn	56dcf497de	various fixes, gc can handle running the whole test suite ... in a loop hundreds of times. the heuristics for growing the heap still cause it to grow very slowly over time, but nonetheless slower than boehm.	2009-06-19 17:57:40 +09:00
Alex Shinn	9e6a0c1300	adding immediate flonum support	2009-06-18 16:15:56 +09:00
Alex Shinn	7e3014ba38	cleanup, removing mid-function returns which could corrupt ... the gc_var trace.	2009-06-18 00:36:39 +09:00
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	c725c48f74	switching to data-driven sexp_mark	2009-06-15 17:34:26 +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	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	a85d80038c	while still working towards the precise gc, reordering the ... context argument to all functions	2009-05-08 23:27:04 +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
