m32c_md_end attempted to pad out a code section with nops, but this was just plain wrong in many ways: - The padding didn't happen at all if the last section emitted wasn't a code section. - The padding went to the wrong place if subsections were used, and the last subseg used wasn't the highest numbered subseg. - Padding wasn't added to all code sections. - If the last section was empty, it was padded to 4 bytes. - The padding didn't go to a 4-byte alignment boundary, instead it effectively made the last instruction 4 bytes in size. - The padding didn't take into account that code sections may have contents other than machine instructions. So, rip it out and handle nop padding properly, also fixing .align .balign/.p2align in the middle of code. gas/ * config/tc-m32c.c (insn_size): Delete static var. (md_begin): Don't set it.
