about GCC dependencies cloog/ppl/isl

[niXman]

Hello,

I produce MinGW builds already about a year. In builds are used
gmp+mpfr+mpc+ppl+cloog. Now I can not remember why I use ppl, and on
the basis of what documentation I have come to this.
Accidentally have I read the list of prerequisites for GCC and found
that there is not a word about ppl, but says only about cloog and isl.
But, nevertheless, I configure GCC using the option '--with-ppl', and
my builds depend on libppl_c-4.dll.
Therefore, I want to find out do I need to use ppl? Is there any
difference what to use - ppl or cloog+isl? What is the difference?


Thanks.

Until recently the optional Graphite loop optimisations required cloog
and ppl. Now trunk requires cloog and isl instead, so you can stop
using ppl on trunk.

I understand.
Thank you!

The last question.
gcc-4_6-branch and the gcc-4_7-branch can be builded using cloog+isl?
Or only with ppl?

Thanks.

I think they still need cloog + ppl, although I could be wrong.

4.7 can use CLooG + ISL, but PPL is still required.  I believe 4.6 is the
same.
