I am in the process of trying to run the gcc testsuite with -mtbm, with and without the patchset, to see (1) if the new insns get used and (2) that they run ok.
FWIW, make check-gcc RUNTESTFLAGS='--target_board=unix/-mtbm execute.exp' shows 204 failures on a host that does not support TBM, so the extension is being used. A browse through exactly one of these used only bextr. Running the same tests with dejagnu using qemu-x86_64 -cpu qemu64,+tbm shows zero failures.
