[gentoo-user] dev-libs/ppl-0.12 breaks gcc?

[gentoo-user] dev-libs/ppl-0.12 breaks gcc?

[Doug Hunley]

I'm currently running ~amd64 and when I ran a world update,
dev-libs/ppl-0.12 was pulled down, compiled and installed. At that
point, gcc stops compiling. It doesn't matter what I try to compile,
whether it's the dev-libs/cloog-ppl rebuild that dev-libs/ppl-0.12.
says to do, a recompile of gcc, or anything else. They all die with
with 'internal compiler error'. I end up having to 'emerge -k gcc' and
then masking dev-libs/ppl-0.12 to get back to a working compiler
chain.

Am I the only one facing this? How did you guys get through the mud here?

What are you using for CFLAGS?

-O2, -pipe, -march and -mtune look fine (though -mtune is implied by
-march), as does -mpopcnt and -msahf. -fomit-frame-pointer is implied
by -O2.

I don't know about the others.

Given you're updating a shared library, I'd wonder about some of these.


I'd also wonder if a depclean and revdep-rebuild prior to upgrading
ppi might reveal something.

Aside. Try:
MAKEOPTS="--jobs --load=6"
(--quiet is default for parallel builds)

Also, try:
EMERGE_DEFAULT_OPTS="--jobs --load-average=6"

-ftree-loop-linear is an alias for -floop-interchange.  They do the same 
thing.

Strange, isn't it. How can those bugs make it into the tree? It's ~arch,
but this should not mean that it hasn't been tested at all.

Nope.

Looking for ppl on bugs.gentoo org, finding bug #412117 [*], rebuilding
ppl and cloog-ppl without -floop* CFLAGS, then again with floop* CFLAGS.

I see you're using gcc's graphite...

Welcome to the club! :-D

Oh, and glad you had the problem fixed ;-)

I can't explain why the "internal compiler error" but I'd guess it's
probably something in your CFLAGS, as the other replies suggested.

But be aware that once you finally get ppl upgraded you'll need to
rebuild cloog-ppl *without* the -floop-* flags because gcc will not
build anything *with* those flags because the old cloog-ppl will
now be broken.  Until you rebuild it, of course.
