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.

JeffBezanson 672558d30f bytecode vm is now working, off by default
various bug fixes

language changes:
• constant symbols no longer shadow everything
• eval* removed
• vararg lists always allocated on entry, dotted argument
  lists not preserved

new applyn() entry point
2009-04-15 00:12:01 +00:00
JeffBezanson 43e8d1fbf0 adding the ability to heap-allocate extentions to the value stack,
so recursion depth is limited only by the process stack limit.

reorganizing evaluator so the same code is used for evaluating
and pushing arguments for both builtin functions and lambdas.
for now this is slower, but it was done in preparation for
Things To Come.

implementing the calling convention for long argument lists in
bytecode compiler. arguments are broken down into a nest of
list and nconc calls.

2008-12-20 06:16:00 +00:00
JeffBezanson 6962211e76 changing representation of cvalue types so each type is
explicitly represented in an fltype_t struct, and symbolic
types are hash-consed. a lot of code is smaller and simpler

characters

ASCII pictures of the mona lisa
