- Authentication-results: sourceware.org; auth=none
- References: <1458593958-25656-1-git-send-email-artemiyv at acm dot org> <20160606192225 dot 12384-1-artemiyv at acm dot org>
This patch adds tests for the initial rvalue reference support patchset. All
of the new tests are practically mirrored regular references tests and, except
for the demangler ones, are introduced in new files, which are set to be
compiled with -std=gnu++11. Tested are printing of rvalue reference types and
values, rvalue reference parameters in function overloading, demangling of
function names containing rvalue reference parameters, casts to rvalue
reference types, application of the sizeof operator to rvalue reference types
and values, and support for rvalue references within the gdb python module.
