Perhaps it's a linker # bug that linker-defined symbols set the symbol-type. # # Note that we smuggle this into OTHER_TEXT_SECTIONS (at the end # of .text) rather than TEXT_START_SYMBOLS. This is necessary, as # DEFINED wouldn't find the symbol if it was at the top; presumably # before the definition, if the definition is not in the first file. # FIXME: Arguably a linker bug. # Only do this for a final link, or else we'll mess up e.g. error # messages.
