Hand-written asm often contains non-function symbols in executable sections. _end symbols for finding the size of instruction blocks for runtime processing is one such usage. optprobe_template_end is one example that causes the warning: objtool: optprobe_template_end(): can't find starting instruction This is because the symbol happens to be at the end of the file (and therefore end of a section in the object file). So ignore end-of-section STT_NOTYPE symbols instead of bailing out because an instruction can't be found. While we're here, add a more descriptive warning for STT_FUNC symbols found at the end of a section. [ This also solves a PowerPC regression reported by Sathvika Vasireddy. ] Reported-by: Naveen N.
