9.26.6 Directives to control code generation
--------------------------------------------
The '.module' directive allows command-line options to be set directly
from assembly. The format of the directive matches the '.set' directive
but only those options which are relevant to a whole module are
supported. The effect of a '.module' directive is the same as the
corresponding command-line option. Where '.set' directives support
returning to a default then the '.module' directives do not as they
define the defaults.
These module-level directives must appear first in assembly.
Traditional MIPS assemblers do not support this directive.
The directive '.set insn32' makes the assembler only use 32-bit
instruction encodings when generating code for the microMIPS processor.
This directive inhibits the use of any 16-bit instructions from that
point on in the assembly. The '.set noinsn32' directive allows 16-bit
instructions to be accepted.
Traditional MIPS assemblers do not support this directive.
