happens in ARM64 (same error for me)
Confirmed, copying arm64@
(In reply to matoro from comment #3) > Confirmed, copying arm64@ cpu_flags_arm_neon is masked on arm64. This appears to be unmasked by users who are unaware of the breakage they introduce in packages such as libpng.

This appears to be unmasked by users > who are unaware of the breakage they introduce in packages such as libpng. I have it set in package.use but that should not override a mask. All I did to get this was: $ cpuid2cpuflags CPU_FLAGS_ARM: edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 aes sha1 sha2 crc32 v4 v5 v6 v7 v8 thumb2 Then I just put that in package.use: */* CPU_FLAGS_ARM: edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 aes sha1 sha2 crc32 v4 v5 v6 v7 v8 thumb2 But a mask should override anything in package.use right? So why would it still apply?

Until 1.6.38, it _did_ work on arm64: # Sam James <sam@gentoo.org> (2021-04-14) # Supports 64-bit NEON # Note: libpng-compat 1.5.30 does NOT seem to. media-libs/libpng -cpu_flags_arm_neon It definitely did work and I'd tested it extensively. So 1.6.38 has broken it somehow.
It was this commit https://sourceforge.net/p/libpng/code/ci/8c542ad9dfc3e7f8a8c790343a43d9cffbc54fd8/ if that helps any.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=6795cc4ecfff4ff5c94a6f6a39e68df0d51e12b6 commit 6795cc4ecfff4ff5c94a6f6a39e68df0d51e12b6 Author: Sam James <sam@gentoo.org> AuthorDate: 2022-09-17 17:48:15 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2022-09-17 17:49:37 +0000 media-libs/libpng: fix NEON on ARM64 As of 1.6.38, =check is banned on arm64 because NEON is always present there. We don't need =check otherwise, so just enable conditionally based on whether cpu_flags_arm_neon is on. (configure also says =check is deprecated/unsupported.) Note that while cpu_flags_arm_neon is masked on arm64 in general, it's unmasked for packages which we know work, like libpng (as it's been fine before 1.6.38).
