Hi
First of all thanks for the continued updates to CLFS.
Some observations and typos on the current build.
1. The date is wrong, surely should be GIT-20120415 ?
2. 5.14. Cross Binutils-2.22
why? --with-cloog=/cross-tools --enable-cloog-backend=isl,
surely binutils doesn't do graphite optimisation, I could
understand this if binutils was built at the same time as gcc,
under the same tree, but it doesn't make sense to me.
3. 6.9. Binutils-2.22
ditto as above --with-ppl=/tools --with-cloog=/tools
--enable-cloog-backend=isl
7. 10.15. Binutils-2.22
ditto item 2
cheers

Hello Martin.
http://sourceware.org/ml/binutils/2012-02/msg00224.html Hmmmmm
maybe we will rectify that, then. When we were talking about it, I
may have asked Cosmo to do that when really we shouldn't be doing
that. I was the one messing with cloog isl backend to get it into
the book.
Sincerely,
William

Thanks, I think the message was the one I saw as well, looks familiar!
Incidentally, I build with a separate isl package available here
http://www.kotnet.org/~skimo/isl/
martin
Current cloog isl uses 0.08. Wouldn't be hard to use the latest isl.
Also, ppl 0.12 will be well. Also I build using cloog 0.17 and it has
openscop, as well. What is lacking is the documentation in the CLFS
build system to use them. For my builds I use -floop-block
-floop-interchange -floop-strip-mine -fgraphite-identity
-floop-parallelize-all We have a graphite toolchain but it isn't
being utilized. MPFR 3.2 will be released soon, and the tree is
looking well. Any comments about the next step to cloog 0.17 and ppl
0.12?
-William

Hi William
For the last couple of builds , I have been using GCC-4.7.0 with an arch
patch so it recognises cloog-0.17 and isl-0.09. is working well so far,
just tried ppl 0.12 as well, so far no problems, but I lack the courage
and documentation to full utilise the graphite.
ops.
For GCC-4.7.0 i had to redo the pure patches and used the following
flags --disable-build-with-cxx --disable-build-poststage1-with-cxx
--with-native-system-header-dir=/tools in building the cross compiler
which got rid of the impure headers warning and enable me to delete the
line where we adjust the start file include prefix
However i had to disable stack smashing protection when constructing the
final libc library in 10.7 other wise it wouldn't build
Other problems encounted were when I upgraded to util-linux-2.21, as I
use the boot method (cross compile from an earlier x86 build to pure
x64), the login utils now have a PAM dependency , so i cheated and used
the earlier versions copy, probably want to cross compile shadow, but I
couldn't get it to work correctly.
cheers
Martin
