-@cindex sequential consistency on 88k
-Do, or don't, generate code to guarantee sequential consistency
-of volatile memory references.  By default, consistency is
-guaranteed.
-
-The order of memory references made by the MC88110 processor does
-not always match the order of the instructions requesting those
-references.  In particular, a load instruction may execute before
-a preceding store instruction.  Such reordering violates
-sequential consistency of volatile memory references, when there
-are multiple processors.   When consistency must be guaranteed,
-GCC generates special instructions, as needed, to force
-execution in the proper order.
-
-The MC88100 processor does not reorder memory references and so
-always provides sequential consistency.  However, by default, GCC
-generates the special instructions to guarantee consistency
-even when you use @option{-m88100}, so that the code may be run on an
-MC88110 processor.  If you intend to run your code only on the
-MC88100 processor, you may use @option{-mno-serialize-volatile}.
-
-The extra code generated to guarantee consistency may affect the
-performance of your application.  If you know that you can safely
-forgo this guarantee, you may use @option{-mno-serialize-volatile}.

-@item -mno-check-zero-division

-@opindex mcheck-zero-division
-@cindex zero division on 88k
-Do, or don't, generate code to guarantee that integer division by
-zero will be detected.  By default, detection is guaranteed.
-
-Some models of the MC88100 processor fail to trap upon integer
-division by zero under certain conditions.  By default, when
-compiling code that might be run on such a processor, GCC
-generates code that explicitly checks for zero-valued divisors
-and traps with exception number 503 when one is detected.  Use of
-@option{-mno-check-zero-division} suppresses such checking for code
-generated to run on an MC88100 processor.
-
-GCC assumes that the MC88110 processor correctly detects all instances
-of integer division by zero.  When @option{-m88110} is specified, no
-explicit checks for zero-valued divisors are generated, and both
-@option{-mcheck-zero-division} and @option{-mno-check-zero-division} are
-ignored.
-
-@item -muse-div-instruction
-@opindex muse-div-instruction
-@cindex divide instruction, 88k
-Use the div instruction for signed integer division on the
-MC88100 processor.  By default, the div instruction is not used.
-
-On the MC88100 processor the signed integer division instruction
-div) traps to the operating system on a negative operand.  The
-operating system transparently completes the operation, but at a
-large cost in execution time.  By default, when compiling code
-that might be run on an MC88100 processor, GCC emulates signed
-integer division using the unsigned integer division instruction
-divu), thereby avoiding the large penalty of a trap to the
-operating system.  Such emulation has its own, smaller, execution
-cost in both time and space.  To the extent that your code's
-important signed integer division operations are performed on two
-nonnegative operands, it may be desirable to use the div
-instruction directly.
-
-On the MC88110 processor the div instruction (also known as the
-divs instruction) processes negative operands without trapping to
-the operating system.  When @option{-m88110} is specified,
-@option{-muse-div-instruction} is ignored, and the div instruction is used
-for signed integer division.
-
-Note that the result of dividing @code{INT_MIN} by @minus{}1 is undefined.  In
-particular, the behavior of such a division with and without
-@option{-muse-div-instruction} may differ.

-@opindex mtrap-large-shift

-@cindex bit shift overflow (88k)
-@cindex large bit shifts (88k)
-Include code to detect bit-shifts of more than 31 bits; respectively,
-trap such shifts or emit code to handle them properly.  By default GCC
-makes no special provision for large bit shifts.
-
-@item -mwarn-passed-structs
-@opindex mwarn-passed-structs
-@cindex structure passing (88k)
-Warn when a function passes a struct as an argument or result.
-Structure-passing conventions have changed during the evolution of the C
-language, and are often the source of portability problems.  By default,
-GCC issues no such warning.
