Use one of the @samp{-A} options to select one of the SPARC
architectures explicitly. If you select an architecture explicitly,
@code{@value{AS}} reports a fatal error if it encounters an instruction
xmpmul, xmontmul and xmontsqr instructions, as well as the instructions
enabled by @samp{-Av8plusv} and @samp{-Av9v}.
+@samp{-Av8plusm8} and @samp{-Av9m8} enable the instructions introduced
+in the Oracle SPARC Architecture 2017 and the M8 processor, as
+well as the instructions enabled by @samp{-Av8plusm} and @samp{-Av9m}.
+
@samp{-Asparc} specifies a v9 environment. It is equivalent to
@samp{-Av9} if the word size is 64-bit, and @samp{-Av8plus} otherwise.
@samp{-Asparc5} is equivalent to @samp{-Av9m}.
+@samp{-Asparc6} is equivalent to @samp{-Av9m8}.

@item -bump
Warn whenever it is necessary to switch to another level.
Select the word size, either 32 bits or 64 bits.
These options are only available with the ELF object file format,
and require that the necessary BFD support has been included.
+
+@item --dcti-couples-detect
+Warn if a DCTI (delayed control transfer instruction) couple is found
+when generating code for a variant of the SPARC architecture in which
+the execution of the couple is unpredictable, or very slow. This is
+disabled by default.
