| 10 : | pazsan | 1.23 | \ forth name stack effect category [pronunciation] |
| 11 : | anton | 1.6 | \ [""glossary entry""] |
| 12 : | \ C code | ||
| 13 : | \ [: | ||
| 14 : | \ Forth code] | ||
| 15 : | \ | ||
| 16 : | pazsan | 1.23 | \ The pronunciation is also used for forming C names. |
| 17 : | \ | ||
| 18 : | \ | ||
| 19 : | anton | 1.6 | \ |
| 20 : | pazsan | 1.23 | \ These informations are automatically translated into C-code for the |
| 21 : | \ interpreter and into some other files. I hope that your C compiler has | ||
| 22 : | anton | 1.6 | \ decent optimization, otherwise the automatically generated code will |
| 23 : | \ be somewhat slow. The Forth version of the code is included for manual | ||
| 24 : | \ compilers, so they will need to compile only the important words. | ||
| 25 : | \ | ||
| 26 : | \ Note that stack pointer adjustment is performed according to stack | ||
| 27 : | \ effect by automatically generated code and NEXT is automatically | ||
| 28 : | \ appended to the C code. Also, you can use the names in the stack | ||
| 29 : | \ effect in the C code. Stack access is automatic. One exception: if | ||
| 30 : | \ your code does not fall through, the results are not stored into the | ||
| 31 : | \ stack. Use different names on both sides of the '--', if you change a | ||
| 32 : | \ value (some stores to the stack are optimized away). | ||
| 33 : | \ | ||
| 34 : | pazsan | 1.23 | \ |
