@opindex mapcs
This is a synonym for @option{-mapcs-frame}.
-@item -mapcs-26
-@opindex mapcs-26
-Generate code for a processor running with a 26-bit program counter,
-and conforming to the function calling standards for the APCS 26-bit
-option. This option replaces the @option{-m2} and @option{-m3} options
-of previous releases of the compiler.
-
-@item -mapcs-32
-@opindex mapcs-32
-Generate code for a processor running with a 32-bit program counter,
-and conforming to the function calling standards for the APCS 32-bit
-option. This option replaces the @option{-m6} option of previous releases
-of the compiler.

@ignore
@c not currently implemented
@item -mapcs-stack-check
big-endian ARM processors generated by versions of the compiler prior to
2.8.
-@item -malignment-traps
-@opindex malignment-traps
-Generate code that will not trap if the MMU has alignment traps enabled.
-On ARM architectures prior to ARMv4, there were no instructions to
-access half-word objects stored in memory. However, when reading from
-memory a feature of the ARM architecture allows a word load to be used,
-even if the address is unaligned, and the processor core will rotate the
-data as it is being loaded. This option tells the compiler that such
-misaligned accesses will cause a MMU trap and that it should instead
-synthesize the access as a series of byte accesses. The compiler can
-still use word accesses to load half-word data if it knows that the
-address is aligned to a word boundary.
-
-This option is ignored when compiling for ARM architecture 4 or later,
-since these processors have instructions to directly access half-word
-objects in memory.
-
-@item -mno-alignment-traps
-@opindex mno-alignment-traps
-Generate code that assumes that the MMU will not trap unaligned
-accesses. This produces better code when the target instruction set
-does not have half-word memory operations (i.e.@: implementations prior to
-ARMv4).
-
-Note that you cannot use this option to access unaligned word objects,
-since the processor will only fetch one 32-bit aligned object from
-memory.
-
-The default setting for most targets is @option{-mno-alignment-traps}, since
-this produces better code when there are no half-word memory
-instructions available.
