altos/scheme: Replace per-type indexed stash with poly stash heap

2017-12-19T20:39:20+00:00

Instead of having a random set of stash arrays with explicit indices used by callers, just have a general heap. Less error prone, and less code. Signed-off-by: Keith Packard

altos/scheme: Replace memory pool macros with inlines

2017-12-19T20:16:24+00:00

AO_SCHEME_IS_CONST -> ao_scheme_is_const_addr AO_SCHEME_IS_POOL -> ao_scheme_is_pool_addr Provides better typechecking and avoids confusion with ao_scheme_is_const inline (which takes an ao_poly instead of a void *) Signed-off-by: Keith Packard

altos/scheme: AO_SCHEME_IS_CONS -> ao_scheme_is_cons

2017-12-19T19:51:33+00:00

This inline was already defined; just use it. Also, switch some places to use ao_scheme_is_pair instead as appropriate. Signed-off-by: Keith Packard

altos/scheme: ao_scheme__cons -> ao_scheme_cons

2017-12-19T19:43:23+00:00

Fix the double underscore in this name. Ick. Signed-off-by: Keith Packard

altos/scheme: Don't optimize ao_scheme_make_const

2017-12-19T19:40:08+00:00

Performance isn't interesting, and it's nice to have a bare system ready for debugging. Signed-off-by: Keith Packard

altos/scheme: Clean up test CFLAGS

2017-12-19T19:39:39+00:00

make it easy to switch between debug and optimized builds. Signed-off-by: Keith Packard

altos/scheme: (define (foo . bar)) has a pair, not list as card

2017-12-19T19:37:33+00:00

When defining a lambda with varargs, the args are not a list as the final element is not a pair or nil. Use pair? instead of list? to detect this form correctly. Signed-off-by: Keith Packard

altos/scheme: apply also needs to not free value list on lambdas

2017-12-19T19:35:09+00:00

When apply is invoked on any function, the cons in the argument list cannot be immediately freed as they have been passed to the function. That applies to both built-ins as well as lambdas; this patch removes the special ao_scheme_skip_cons_free global and just marks the stack in both cases. Signed-off-by: Keith Packard

altos/scheme: Rework display/write code

2017-12-19T19:33:36+00:00

Unify output functions and add bool to switch between write and display mode. Make that only affect strings (as per r⁷rs). Use print recursion detection in frame and stack code, eliminating PRINT flags in type field. Signed-off-by: Keith Packard

altos/scheme: Compile scheme test with -O3

2017-12-18T10:14:57+00:00

This level of optimization caused trouble, so use it all of the time. Signed-off-by: Keith Packard
