PR 78303 was recently marked RESOLVED, WONTFIX. The resolution was to
deprecate the troublesome command-line option.
This patch begins the process of deprecation by issuing a warning
message when this command-line option is specified. The patch has
bootstrapped and tested without regressions on
powerpc64le-unknown-linux. Is this ok for trunk?
gcc/ChangeLog:
2018-02-13 Kelvin Nilsen <kel...@gcc.gnu.org>
* config/rs6000/rs6000.c (rs6000_option_override_internal): Issue
warning message if user requests -maltivec=be.
gcc/testsuite/ChangeLog:
2018-02-13 Kelvin Nilsen <kel...@gcc.gnu.org>

this test case still works ok.
