-These @samp{-m} options are defined for picoChip implementations:
-
-@table @gcctabopt
-
-@item -mae=@var{ae_type}
-@opindex mcpu
-Set the instruction set, register set, and instruction scheduling
-parameters for array element type @var{ae_type}.  Supported values
-for @var{ae_type} are @samp{ANY}, @samp{MUL}, and @samp{MAC}.
-
-@option{-mae=ANY} selects a completely generic AE type.  Code
-generated with this option runs on any of the other AE types.  The
-code is not as efficient as it would be if compiled for a specific
-AE type, and some types of operation (e.g., multiplication) do not
-work properly on all types of AE.
-
-@option{-mae=MUL} selects a MUL AE type.  This is the most useful AE type
-for compiled code, and is the default.
-
-@option{-mae=MAC} selects a DSP-style MAC AE.  Code compiled with this
-option may suffer from poor performance of byte (char) manipulation,
-since the DSP AE does not provide hardware support for byte load/stores.
-
-@item -msymbol-as-address
-Enable the compiler to directly use a symbol name as an address in a
-load/store instruction, without first loading it into a
-register.  Typically, the use of this option generates larger
-programs, which run faster than when the option isn't used.  However, the
-results vary from program to program, so it is left as a user option,
-rather than being permanently enabled.
-
-@item -mno-inefficient-warnings
-Disables warnings about the generation of inefficient code.  These
-warnings can be generated, for example, when compiling code that
-performs byte-level memory operations on the MAC AE type.  The MAC AE has
-no hardware support for byte-level memory operations, so all byte
-load/stores must be synthesized from word load/store operations.  This is
-inefficient and a warning is generated to indicate
-that you should rewrite the code to avoid byte operations, or to target
-an AE type that has the necessary hardware support.  This option disables
-these warnings.
