Re: Stop Gas from generating line info or address ranges
* doc/as.texi (.nop): Document optional size arg.
* dwarf2dbg.c (dwarf2_gen_line_info_1): Only check SEC_ALLOC
when ELF. Warn whenever dwarf line number information is ignored.
* frags.c (frag_offset_ignore_align_p): New function.
* frags.h (frag_offset_ignore_align_p): Declare.
* read.c (s_nop): Extend to support optional size arg.
* testsuite/gas/elf/dwarf2-20.d: Expect warnings, and exact range.
* testsuite/gas/elf/dwarf2-20.s: Emit 16 bytes worth of nops.
* testsuite/gas/m68hc11/indexed12.d: Expect warnings.
