Hi,
while working on cp_build_binary_op I noticed that the testsuite wasn't
exercising the warnings in case RROTATE_EXPR / LROTATE_EXPR, even more
the code handling those tree codes seemed completely unused. Turned out
that the C front-end doesn't handle those tree codes at all: I'm coming
to the conclusion that the C++ front-end bits too are now obsolete and
may be removed, because only the middle-end generates those codes in
order to implement optimizations. Anything I'm missing? Any additional
testing? Tested x86_64-linux.
Thanks, Paolo.
