Description Tony Ducrocq 2013-01-29 18:58:03 UTC
Compilation fail for all version of mlt that I tryed to build.

I've tryed to basically do a ./configure && make on mlt-0.8.8 and it seems to compile.

emerge --info '=media-libs/mlt-0.8.8'

Comment 2 Jeroen Roovers (RETIRED) gentoo-dev 2013-01-29 20:43:13 UTC
What if you removed -ftree-vectorize from CFLAGS?
Comment 3 Tony Ducrocq 2013-01-29 20:49:15 UTC
removing -ftree-vectorize did not solve the problem but putting CFLAGS="" solved it. I'll try removing it one by one to find the one that is problematic.

Anyway thanks for the help.
Comment 4 Tony Ducrocq 2013-01-29 20:57:06 UTC
The problem do not come from one flags but a combination of several, don't know which one know but it works with

CFLAGS="-march=bdver1 -mprefer-avx128 -mno-3dnow -ftree-vectorize -funroll-all-loops -fprefetch-loop-arrays --param prefetch-latency=300 -pipe -mtune=bdver1"

works also with

CFLAGS="O2"

but do not work with both.
Comment 5 Tony Ducrocq 2013-01-29 21:02:05 UTC
The minimal combination of problematic CFLAGS seems to be :

CFLAGS="-O2 -fprefetch-loop-arrays"

maybe some other also but I didn't try all the combinations.
Comment 6 Ben de Groot (RETIRED) gentoo-dev 2013-02-01 10:14:17 UTC
As long as it works with CFLAGS="-O2 -march=native" then it's good enough for us, and we probably won't take any action on this bug.
Comment 7 Alexis Ballier gentoo-dev 2013-07-12 13:12:34 UTC
its a gcc ICE, reassigning to toolchain@
Comment 9 Ryan Hill (RETIRED) gentoo-dev 2013-12-24 00:59:18 UTC
Fixed in 4.6.3 p1.1.
