1.1 |
- major size optimisations |
| 12 |
|
|
- struct layout for both typical CISC and RISC cpus. |
| 13 |
|
|
- optional error messages. |
| 14 |
|
|
- optional error checking. |
| 15 |
root |
1.3 |
- cell size reduced by not storing both float and int forms of a number, |
| 16 |
root |
1.1 |
- major dependency optimisations (no stdio etc.) |
| 17 |
root |
1.2 |
- faster and vastly simpler vector memory management (execution speed |
| 18 |
|
|
is roughly twice faster than tinyscheme when optimised for size, and 2.5 |
| 19 |
|
|
times faster when optimised for speed). |
| 20 |
root |
1.1 |
- no need for consecutive cells |
| 21 |
|
|
- more compact and faster vectors. |
| 22 |
root |
1.6 |
- resizable vectors (TODO: not exposed yet). |
| 23 |
root |
1.4 |
- faster environment implementation, not hashed by name but by symbol address. |
| 24 |
root |
1.6 |
- simpler and faster memory management (no need for sorted free lists). |
| 25 |
root |
1.1 |
- much faster call stack implementation, fully supporting continuations, |
| 26 |
|
|
while greatly reducing cell thrashing, thus fewer gc's and overall |
| 27 |
|
|
much faster execution. |
| 28 |
root |
1.10 |
- move caaaar etc. to C, which should effectively save some memory |
| 29 |
root |
1.11 |
(and should also be faster). |
| 30 |
root |
1.6 |
- allow full 32 bit size range for strings and vectors, where possible. |
| 31 |
root |
1.1 |
- made ports optional. |
| 32 |
|
|
- made error checking and error strings optional. |
| 33 |
root |
1.11 |
- implemented small-integer cache, reducing number of cells allocated. |
| 34 |
root |
1.1 |
- ripped out features: dynamic loading, nonstandard C targets. |
| 35 |
|
|
- fix numerous ISO C violations (mostly _ namespace). |
| 36 |
|
|
- fix numerous uninitialised value violations. |
| 37 |
root |
1.6 |
- fix some bufer overflows (mostly relying on _snprintf terminating with 0). |
| 38 |
root |
1.1 |
- fix numerous sign/truncation problems. |
| 39 |
|
|
- remove limit of 65535 args maximum. |
| 40 |
root |
1.6 |
- move ~6kb opcode table into read-only segemnt, saves 6kb rss. |
| 41 |
|
|
- reduce ~6kb opcode table to 1.2kb. |
| 42 |
root |
1.8 |
- symbols use one cell instead of two now. |
| 43 |
root |
1.1 |
- subnormals are no longer flushed to zero in some comparisons. |
| 44 |
root |
1.16 |
- new procedure: gensym? |
| 45 |
root |
1.6 |
- scheme fix: gensym does not intern the symbol. |
| 46 |
root |
1.7 |
- scheme fix: properly support symbol names starting with '.' |
| 47 |
|
|
- scheme improvement: support |identifier| syntax. |
| 48 |
root |
1.19 |
- numerous R7RS improvements: |
| 49 |
|
|
- many added procedures. |
| 50 |
|
|
- aligned existing procedures. |
| 51 |
|
|
- multiline string (\whitespace) parsing. |
| 52 |
root |
1.12 |
- removed unused 1kb linebuf from scheme context. |
| 53 |
root |
1.13 |
- abstract cell pointer types, to quickly experiment with different |
| 54 |
|
|
representations. |
| 55 |
root |
1.14 |
- use c99 rounding functions. |
