[Comment 1 Paweł Hajdan, Jr. (RETIRED) 2013-11-23 19:11:11 UTC]

Actually chromium-31.0.1650.57 and 32 is also affected. I wonder why this wasn't reported by anyone before.

[Comment 2 Steev Klimaszewski (RETIRED) 2013-11-24 09:29:26 UTC]

If I had to wager a guess, it's because chromium takes a while to build, so once we have a working version, we have it keyworded as "=www-client/chromium-30.0.1599.101" in the package.accept_keywords/chromium file, and so we don't upgrade it every single time there is a new version pushed into portage :)

That said, I can take a look tomorrow sometime, the Samsung has been sitting by idling while I've been working on SELinux as well as Xen for ARM.  There's only so much time to spare.

[Comment 3 Mikhail Kurinnoi 2013-11-25 21:15:08 UTC]

I did't have any issues with www-client/chromium (30,31 and 32 versions) and neon support. Just now emerged www-client/chromium-32.0.1700.19 with "neon" USE flag on my ARM box.
As I see, you are using -mfpu=vfpv3 in CXXFLAGS, here is mine:
CXXFLAGS="-O2 -pipe -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=hard"

Probably, "Error: selected FPU does not support instruction -- `vmov.i32 q9,#0'" error line could be connected to wrong mfpu (vfpv3 instead of neon)?

[Comment 4 Steev Klimaszewski (RETIRED) 2013-11-25 21:55:40 UTC]

More specifically, it should not be enabling neon code without neon support being enabled - either via neon in mfpu or a useflag of some sort.

We're running into something very similar in Firefox, when libpng is built with the neon useflag enabled, but users don't have mfpu=neon.

It SHOULD be possible to use neon code even when mfpu!=neon, at least, that's my understanding of it.  I could be wrong though.

[Comment 5 Paweł Hajdan, Jr. (RETIRED) 2014-06-09 06:57:33 UTC]

It seems fixed as of www-client/chromium-36.0.1985.1 on ~arm.
