System: NetBSD shamshu.zia.io 10.0_STABLE NetBSD 10.0_STABLE (GENERIC64) #0: Thu Aug 1 20:53:39 UTC 2024 john@shamshu.zia.io:/usr/obj-evbarm/sys/arch/evbarm/compile/GENERIC64 evbarm
Architecture: aarch64
Machine: evbarm
>Description:

When attempting to compile recent (130 and greater) firefox on aarch64, 
the compile fails with:

ld: ../../../media/libyuv/libyuv/libyuv_libyuv/convert.o: in function `ARGBToI420':
convert.cc:(.text.ARGBToI420+0xf0): undefined reference to `ARGBToUVRow_SVE2'
ld: convert.cc:(.text.ARGBToI420+0xf8): undefined reference to `ARGBToUVRow_SVE2'
ld: ../../../media/libyuv/libyuv/libyuv_libyuv/convert.o: in function `BGRAToI420':
convert.cc:(.text.BGRAToI420+0xf0): undefined reference to `BGRAToUVRow_SVE2'
ld: convert.cc:(.text.BGRAToI420+0xf8): undefined reference to `BGRAToUVRow_SVE2'
ld: ../../../media/libyuv/libyuv/libyuv_libyuv/convert.o: in function `ABGRToI420':

and so on.
>How-To-Repeat:

Attempt to compile www/firefox on NetBSD/aarch64
>Fix:

SVE2 is not available on my machines, and I don't know why the SVE2 
versions of functions is being referred to here.

Swapping the SVE2 functions with NEON ones works, though, and would work for 
all aarch64 since NEON is a requirement for aarch64:

sed -i 's/_SVE2/_NEON/g' work/firefox-130.0.1/media/libyuv/libyuv/source/convert.cc
sed -i 's/_SVE2/_NEON/g' work/firefox-130.0.1/media/libyuv/libyuv/source/scale_argb.cc
sed -i 's/_SVE2/_NEON/g' work/firefox-130.0.1/media/libyuv/libyuv/source/convert_argb.cc

 There is something wrong in the upstream code. When the build system 
 detects that the assembler on the build machine cannot do SVE2, it 
 correctly suppresses compiling functions like I444ToARGBRow_SVE2(). 
 However, it fails to tell potential users of those functions to not use 
 the SVE2 implementation, which results in references to missing symbols. 
 We don't know the cause of this but jklos@'s hack works fine.
