| Source code for C/C++ system libaries |
| ===================================== |
| |
| This directory contains the source code for libc, libc++ and other C/C++ system |
| libraries. Where possible these are clones of upstream projects (e.g. musl). |
| For more details about each library see the individual readme files in the |
| subdirectoris. |
| |
| Static constructor ordering |
| --------------------------- |
| |
| These are several static constructors in the emscripten system libraries and they |
| are in a specific order. When adding/remove/updating these please update this |
| document. |
| |
| These current set of static constructors in system libraries and their priorities |
| (lowest run first) are: |
| |
| - 47: `initialize_emmalloc_heap` (emmalloc.c) |
| - 48: `__emscripten_init_main_thread` (pthread/library_pthread.c) |
| - 50: asan init (??) |
| |
| Priorities 0 - 100 are reserved for system libraries and user-level |
| constructors should all run at 101 and above (for example libc++ initializes |
| its standard I/O streams at priority 101). |
