16 | | // The main() functions in typical LLVM tools start with InitLLVM which does |
17 | | // the following one-time initializations: |
18 | | // |
19 | | // 1. Setting up a signal handler so that pretty stack trace is printed out |
20 | | // if a process crashes. |
21 | | // |
22 | | // 2. Set up the global new-handler which is called when a memory allocation |
23 | | // attempt fails. |
24 | | // |
25 | | // 3. If running on Windows, obtain command line arguments using a |
26 | | // multibyte character-aware API and convert arguments into UTF-8 |
27 | | // encoding, so that you can assume that command line arguments are |
28 | | // always encoded in UTF-8 on any platform. |
29 | | // |
30 | | // InitLLVM calls llvm_shutdown() on destruction, which cleans up |
31 | | // ManagedStatic objects. |
