As far as I know, the Pi5 does not. I can put the build log in my devspace if you want all 202M of it. Reproducible: Always Steps to Reproduce: 1. emerge chromium on a Pi5 (maybe any arb64?) 2. wait ... get a good sleep 3. observe the failure close to the end of the build. Actual Results: ld.lld: error: undefined symbol: __arm_tpidr2_save Expected Results: After a few more hours, chromium installs and works.
XZ_OPT=-9e tar cJvf logs.tar logs would compress the logs nicely
I've lost the log. I'll build it again. Its only 27 hours.

../../third_party/libyuv/source/row_sve.cc -o obj/third_party/libyuv/libyuv_sve/row_sve.o Its actually an armv8.2-a+crc+crypto CPU, not an armv9a+ as that grep suggests. It will be this time tomorrow before I have the 200+MB build log.
We'll have to wait for the full logs, but this feels like another case of CPU detection gone awry. Can we get an `emerge --info` from that box too?
The complete build log is in my devspace at neddyseagoon@woodpecker ~ $ ls public_html/chromium-133.0.6943.27_build.log.tar.xz -l -rw-r--r-- 1 neddyseagoon users 1457792 Feb 1 20:54 public_html/chromium-133.0.6943.27_build.log.tar.xz Its available to the world at https://dev.gentoo.org/~neddyseagoon/chromium-133.0.6943.27_build.log.tar.xz The compressor had a good go but its too big for a 1.4M floppy. so it won't attach to a bug. I know about --tape-length and split to break a file into pieces too but then it has to be reassembled.

Have reproduced this on an aarch64 VM at Hetzner with 133.0.6943.98
See https://forums.gentoo.org/viewtopic-p-8854657.html#8854657 In particular ... The accomodation for CPU flags in recent Chromium seems to be whack and halfassed. Some of the bundled libraries are all hardcoded to expect later ARM revisions. There is no arm_use_neon_dotprod nor arm_use_sve, etc. For example, libdav1d's preconfigured define headers expect v8.6 and newer. Because they are headers we have to sed patch them if we are expected to make them bend to our will.
