+@item -mtune=itanium1
+@itemx -mtune=itanium2
+Tune for a particular IA-64 CPU, @var{itanium1} or @var{itanium2}. The
+default is @var{itanium2}.
+
+@item -munwind-check=warning
+@itemx -munwind-check=error
+These options control what the assembler will do when performing
+consistency checks on unwind directives. @code{-munwind-check=warning}
+will make the assembler issue a warning when an unwind directive check
+fails. This is the default. @code{-munwind-check=error} will make the
+assembler issue an error when an unwind directive check fails.
+
+@item -mhint.b=ok
+@itemx -mhint.b=warning
+@itemx -mhint.b=error
+These options control what the assembler will do when the @samp{hint.b}
+instruction is used. @code{-mhint.b=ok} will make the assembler accept
+@samp{hint.b}. @code{-mint.b=warning} will make the assembler issue a
+warning when @samp{hint.b} is used. @code{-mhint.b=error} will make
+the assembler treat @samp{hint.b} as an error, which is the default.
