\ Batching: |
| |
|
| |
\ New words are deferred, and the corresponding C functions are |
| |
\ collected in one file, until the first word is EXECUTEd; then the |
| |
\ file is compiled and linked into the system, and the word is |
| |
\ resolved. |
| |
|
| |
\ Caching: |
| |
|
| |
\ Instead of compiling all this stuff anew for every execution, we |
| |
\ keep the files around and have an index file containing the function |
| |
\ names and their corresponding .so files. If the needed wrapper name |
| |
\ is already present, it is just linked instead of generating the |
| |
\ wrapper again. This is all done by loading the index file(s?), |
| |
\ which define words for the wrappers in a separate wordlist. |
| |
|
| |
\ The files are built in .../lib/gforth/$VERSION/libcc/ or |
| |
\ ~/.gforth/libcc/$HOST/. |
