| 35 """Generate aggregate .cpp files that include multiple V8 binding .cpp files. |
| 36 |
| 37 This can be a single output file, to preserve symbol space; or multiple output |
| 38 files, to reduce maximum compilation unit size and allow parallel compilation. |
| 39 |
| 40 Usage: |
| 41 aggregate_generated_bindings.py COMPONENT_DIR IDL_FILES_LIST -- OUTPUT_FILE1 OUT
PUT_FILE2 ... |
| 42 |
| 43 COMPONENT_DIR is the relative directory of a component, e.g., 'core', 'modules'. |
| 44 IDL_FILES_LIST is a text file containing the IDL file paths, so the command |
| 45 line doesn't exceed OS length limits. |
| 46 OUTPUT_FILE1 etc. are filenames of output files. |
