109 A try block hole is used to represent a non-contiguous part of
110 of a segment of native code protected by a given .try block.
111 Usually, a try block is defined as a contiguous segment of code.
112 But in some cases it's needed to have some parts of it to not be protected.
113 For example, given "try {} finally {}", the code in the .try block to call
114 the finally part looks like:
120 jump outside try block
126 The instructions between the call and the jump should not be under the try block since they happen
127 after the finally block executes, which means if an async exceptions happens at that point we would
128 execute the finally clause twice. So, to avoid this, we introduce a hole in the try block to signal
129 that those instructions are not protected.
