JeffBezanson 3793cf676c implementing stack traces
some cleanup
2009-07-06 03:56:48 +00:00
JeffBezanson 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.
2009-07-03 18:43:15 +00:00
JeffBezanson 2f78b407ea some renaming (intern is now symbol) and moving stuff around

2009-06-30 03:21:41 +00:00
JeffBezanson 3844191d70 adding the ability for the VM to use computed goto where available
with gcc v4.3.2 I found the combination of -O2 and computed goto to give the
best performance; with -O3 performance was a little worse and computed goto
was a wash.
