b67cd85cb4
2 bugs fixed:
...
empty string will be true in conditional expressions,but now it is false(and string that is not empty and is not numerable will be true)
foreach(var i;func(){return []}()); will cause sigsegv because codegen generates error op_pop and op_cntpop,now the counter in_foreach and in_forindex change after generating
foreach/forindex expression before block generation.

...
change parameter type to avoid unnecessary copies of string.
change stack depth from 65536<<4 to 16+(65536<<2).
now you could know stack overflow when it happens

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
b2e85de7a7
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.
2021-05-31 19:10:59 +08:00

bug fixed
