This description makes no sense to me. Whatever you do, the address where the image starts executuin is what is called the entry point. Whether this is needs special code to swutch to thumb mode or not does not make any difference. Whichever address you use with the "go" command is the "entry point". Also, can the mode switching not be done inside the body of the regular hello_world() function? This would be much better as it wuld allow to always use the same method to determine the entry point address (line running "nm" on the binary and grepping for the name "hello_world"). With your code, you would have to fix all documentation and explain that the entry pooint name is suddenly domething totally different (and an unexpected, unusal name like "dummy2" as well) for thumb images. Sorry, but this does not seem a good idea to me.
