Add a new ".nop" directive to the assembler to allow the creation of no-op instructions in an architeture neutral manner.
* read.c (s_nop): New function. Handles the .nop directive.
(potable): Add entry for "nop".
(s_nops): Code tidy.
* read.h (s_nop): Add prototype.
* config/tc-bpf.h (md_single_noop_insn): Define.
* config/tc-mmix.h (md_single_noop_insn): Define.
* config/tc-or1k.h (md_single_noop_insn): Define.
* config/tc-s12z.c (md_assemble): Preserve the input line pointer,
rather than corrupting it.
* write.c (relax_segment): Update error message regarding
non-absolute values passed to .fill and .nops.
* NEWS: Mention the new directive.
* doc/as.texi: Document the new directive.
* doc/internals.texi: Document the new internal macros used to
implement the new directive.
* testsuite/gas/all/nop.s: New test.
* testsuite/gas/all/nop.d: New test control file.
* testsuite/gas/all/gas.exp: Run the new test.
* testsuite/gas/elf/dwarf-5-nop-for-line-table.s: New test.
* testsuite/gas/elf/dwarf-5-nop-for-line-table.d: New test
control file.
* testsuite/gas/elf/elf.exp: Run the new test.
* testsuite/gas/i386/space1.l: Adjust expected output.
