This commit fixes a bug where clang/llvm doesn't emit an unwind table
for a function when it is marked noexcept. Without this patch, the
following code terminates with an uncaught exception on ARM64:
int foo1() noexcept {
try {
throw 0;
} catch (int i) {
return 0;
}
return 1;
}
int main() {
return foo1();
}
