I probably don't understand the compiler, but I have been trying
with -static and without, using -Wall -Wextra -v -save-temps
-ftree-parallelize-loops=12 -O2 -std=c++11
I have also tried 0 on that number with same results.
I always get single-threaded programs, and my stuff contains a lot of vectors
and loops.
I have also tried with -floop-parallelize-all -ftree-slp-vectorize
additionally with same results.
it's like that -ftree-parallize-loops is being ignored by the compiler. I did
what everybody said and used the posix/pthreads version. this has not helped.
auto-threadind seems broken in 4.9.0 v3rev2.
I see libgcc_s_sjlj.a but not libgcc_s_pthread.a there's probably a reason for
this, or maybe it's a mistake. I don't know. maybe someone else can figure this
out.
