These @samp{-m} options are defined for the HPPA family of computers:
@table @code
@item -mpa-risc-1-0
Generate code for a PA 1.0 processor.
@item -march=@var{architecture type}
Generate code for the specified architecture. The choices for
@var{architecture type} are @samp{1.0} for PA 1.0, @samp{1.1} for PA
1.1, and @samp{2.0} for PA 2.0 processors. Refer to
@file{/usr/lib/sched.models} on an HP-UX system to determine the proper
architecture option for your machine. Code compiled for lower numbered
architectures will run on higher numbered architectures, but not the
other way around.
PA 2.0 support currently requires gas snapshot 19990413 or later. The
next release of binutils (current is 2.9.1) will probably contain PA 2.0
support.
@item -mpa-risc-1-0
@item -mpa-risc-1-1
Generate code for a PA 1.1 processor.
@item -mpa-risc-2-0
Synonyms for -march=1.0, -march=1.1, and -march=2.0 respectively.
@item -mbig-switch
Generate code suitable for big switch tables. Use this option only if
