Valk Richard Li	166fe32839	front end optimization&stack overflow prompt ... 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	2021-06-07 23:53:43 +08:00
Valk Richard Li	a3dbaebfd8	bug fixed ... fixed SIGSEGV when failed to load file in nasal_lexer::openfile	2021-06-06 19:17:02 +08:00
Valk Richard Li	a3d629a08e	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
Valk Richard Li	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
