TODO: call/cc broken with or with SCHEME_STACK, also in tinyscheme |
| 3 |
TODO: fix .atom names |

TODO: |name|? (TOK_STRATOM) |

TODO: simpler cell memory management, only one block |

|
| 7 |
- major size optimisations |
| 8 |
- struct layout for both typical CISC and RISC cpus. |
| 9 |
- optional error messages. |
| 10 |
- optional error checking. |
| 11 |
- cell size reduced by not storing both float and int forms of a number, |
| 12 |
- major dependency optimisations (no stdio etc.) |
| 13 |
- faster and vastly simpler vector memory management (execution speed |
| 14 |
is roughly twice faster than tinyscheme when optimised for size, and 2.5 |
| 15 |
times faster when optimised for speed). |
| 16 |
- no need for consecutive cells |
| 17 |
- more compact and faster vectors. |
| 18 |
- resizable vectors (TODO: not exposed yet). |
| 19 |
- faster environment implementation, not hashed by name but by symbol address. |
| 20 |
- simpler and faster memory management (no need for sorted free lists). |
| 21 |
- much faster call stack implementation, fully supporting continuations, |
| 22 |
while greatly reducing cell thrashing, thus fewer gc's and overall |
| 23 |
much faster execution. |
| 24 |
- allow full 32 bit size range for strings and vectors, where possible. |
| 25 |
- made ports optional. |
| 26 |
- made error checking and error strings optional. |
| 27 |
- ripped out features: dynamic loading, nonstandard C targets. |
| 28 |
- fix numerous ISO C violations (mostly _ namespace). |
| 29 |
- fix numerous uninitialised value violations. |
| 30 |
- fix some bufer overflows (mostly relying on _snprintf terminating with 0). |
| 31 |
- fix numerous sign/truncation problems. |
| 32 |
- remove limit of 65535 args maximum. |
| 33 |
- move ~6kb opcode table into read-only segemnt, saves 6kb rss. |
| 34 |
- reduce ~6kb opcode table to 1.2kb. |
| 35 |
- subnormals are no longer flushed to zero in some comparisons. |
| 36 |
- scheme fix: gensym does not intern the symbol. |
| 37 |
- scheme fix: properly support atom names starting with '.' |
