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@localhost:/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
