[Gomp-discuss] Decision about semaphores ..

[Lars Segerlund]

 I am trying to write some semaphores for the fork/join of threads, ( 
more specificly the join ), and I have the decision on using primitives 
from POSIX threads, or an asm macro using native instructions in the 
target cpu to do atomic updates.

 What is the opinion on this among you people ?

 The native instruction approach is FAST, however it would be easier to 
support different architectures by using the threading lib ?

 It's just the overhead of the join and such that concerns me.
