================
Comment at: lib/Target/WebAssembly/WebAssemblyExceptionInfo.cpp:25-26
+/// Because CFGSort requires all the BBs within a catch part to be sorted
+/// together as it does for loops, this pass calculates the nesting structure of
+/// catch part of exceptions in a function.

Like loop nesting structure, catch block structure should form a nested structure, so a BB belongs to both catch1 and catch2, catch1 should contain catch2 or vice versa.
