\ 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/. |
