Comment (by guest):
I have tried some SSE instructions using harpy in GHC-6.10, but the test
program terminates with:
{{{ghci: pthread_mutex_lock.c:82: __pthread_mutex_lock: Assertion
`mutex->__data.__owner == 0' failed.}}}
Of course, this can be due to a programming error. However, is the Haskell
runtime prepared for SSE instructions at all? If two threads use XMM
registers - do their usage of these registers interfer?
