@opindex mcpu=
Specifies the ISA to use. Accepted values are @samp{msp430},
@samp{f5series} for the 16/32-bit multiply supported by F5-series MCUs.
A value of @samp{auto} can also be given. This tells GCC to deduce
the hardware multiply support based upon the MCU name provided by the
-@option{-mmcu} option. If no @option{-mmcu} option is specified then
-@samp{32bit} hardware multiply support is assumed. If the MCU name is
-not recognised then no hardware multiply support is assumed.
-@code{auto} is the default setting.

Hardware multiplies are normally performed by calling a library
routine. This saves space in the generated code. When compiling at
