| ## This file is generated from the following C++ source code. |
| ## |
| ## ``` |
| ## int main() { |
| ## try { |
| ## throw 42; |
| ## } catch (...) { |
| ## return 0; |
| ## } |
| ## return 1; |
| ## } |
| ## ``` |
| ## The exception table is modified to use udata4 encoding for LPStart and |
| ## sdata4 encoding for call sites. |
