Hi,
What do you think to a new switch for cc?
cc has the extra compiler options -pthread and -kthread which invoke
the userland pthreads or the kernel threads respectivly.
How easy would it be to change this to
cc -pthread *New meaning*. It invokes either -uthread or -kthread,
depending on a
envoronment variable or a setting in a config file (eg
/etc/thread_type)
cc -uthread use useland threads (what is currently -pthread)
cc -kthread use kernel threads
I compile pthreaded code on several machines, some uni-processor,
some SMP using kthreads and Luoqi's SMP thread patches.
It means I could have one makefile, with just the -pthread option, and
compile my
code on all my machines with the same makefile.
Is this even possible?
(there is the problem of issuing the -DLINUXTHREAD option alongside
-kthread, but
perhaps this is already done)
Comment please?
Bye
Roger
