2009-07-06 03:56:48 +00:00
494e439510
using lisp value stack for call frames instead of the C stack
...
adding the ability to grow the value stack as needed
the net effect is that calls use much less space, and stack frames
can use all available heap space. the only downside is that C builtins
must be aware that the stack can change out from under them if they call
lisp code. currently the only example of this is table.foldl.
also fixing bug where exceptions failed to unwind the gc handle stack.

best performance; with -O3 performance was a little worse and computed goto
was a wash.

bfbbf051c9
doing a better job hashing circular structure. the hash function is now
...
always fast and gives conservative correct answers, at the expense of
fidelity on medium and large size structures. for example (hash (iota 15))
gives the same result as (hash (iota 14)).
