Can someone with access to ARM please run libs/smart_ptr/test/spinlock_test.cpp and/or take a look at boost/detail/spinlock_gcc_arm.hpp? I've verified that it compiles, but can't run it. What is the expected behavior? I get no output, no CPU usage, and an indefinite running time.
This means a deadlock. The test just locks and unlocks two spinlocks, the expected behavior is to return immediately. You can try spinlock_try_test.cpp which might produce some output.
OK, I made it output which code it's going to execute. And it only gets as far as the first call: ==== coda$ ./spinlock_test // sp.lock(); // boost::detail::yield( 0 ); // boost::detail::yield( 1 ); // boost::detail::yield( 2 ); // boost::detail::yield( 3 ); // boost::detail::yield( 4 ); [and so on...] ====
Here's the relevant portion of spinlock_gcc_arm.hpp:
bool try_lock() [...]
That would help if I knew ARM assembly ;-) -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail
