Clang is unable to handle the situation that a chunk of inline assembly ends with a compat branch instruction and then compiler generates another control transfer instruction immediately after this compat branch. The later instruction will end up in forbidden slot and cause exception. Workaround by add a option to control the use of compact branch. Currently it's selected by CC_IS_CLANG and hopefully we can change it to a version check in future if clang manages to fix it. Fix boot on boston board.
