| Hans-G?nter@25079 | 1 Orc is basically a simplified assembly language for data processing |
| Hans-G?nter@25079 | 2 (no loops, jumps etc.), it's supposed to map to SIMD instructions on |
| Hans-G?nter@25079 | 3 various architectures curently there are two things: |
| Hans-G?nter@25079 | 4 |
| Hans-G?nter@25079 | 5 - liborc, which is a JIT compiler that will at run-time take orc code |
| Hans-G?nter@25079 | 6 (in some byte format) and generate machine code for the architecture |
| Hans-G?nter@25079 | 7 in question on the fly and then execute that whenever there's a |
| Hans-G?nter@25079 | 8 function call |
| Hans-G?nter@25079 | 9 - we have C backup functions as .c files in the gstreamer source code, |
| Hans-G?nter@25079 | 10 which are also compiled in when orc can't compile some code (for |
| Hans-G?nter@25079 | 11 various reasons), or liborc is not available, then the C backup |
| Hans-G?nter@25079 | 12 function will be used that's the current state of things. |
