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. gdb/ChnageLog PR gdb/14441 * NEWS: Mention support for rvalue references in GDB and python. * doc/gdb.texinfo (C Plus Plus Expressions): Mention that GDB supports both lvalue and rvalue references. gdb/testsuite/ChangeLog PR gdb/14441 * gdb.cp/demangle.exp: Add rvalue reference tests. * gdb.cp/rvalue-ref-casts.cc: New file. * gdb.cp/rvalue-ref-casts.exp: New file. * gdb.cp/rvalue-ref-overload.cc: New file. * gdb.cp/rvalue-ref-overload.exp: New file. * gdb.cp/rvalue-ref-params.cc: New file. * gdb.cp/rvalue-ref-params.exp: New file. * gdb.cp/rvalue-ref-sizeof.cc: New file. * gdb.cp/rvalue-ref-sizeof.exp: New file. * gdb.cp/rvalue-ref-types.cc: New file. * gdb.cp/rvalue-ref-types.exp: New file. * gdb.python/py-rvalue-ref-value-cc.cc: New file. * gdb.python/py-rvalue-ref-value-cc.exp: New file.
