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
