bug fixed & more efficient callfv
...
I changed callfv's way of calling a function with arguments in vm_vec.
now callfv fetches arguments from val_stack directly,so it runs test/fib.nas from 2.4s to 1.9s.
delete operand callf,add operands callfv & callfh.
also,i check val_stack's top to make sure there is not a stack overflow.
2021-06-03 21:49:31 +08:00

bug fixed
...
a gc bug which causes fatal error.
add member value collect to make sure that nasal_val is not collected repeatedly.
use builtin_alloc in builtin function to avoid incorrect collection of value in use(gc_alloc).
change free_list to free_list[vm_type_size] to avoid too many calls of new/delete(but seems useless?)
but the most important thing is fixing this bug.
