configure is
CC="clang -Wall -Wextra" CXX="clang++ -Wall -Wextra" \
../trunk/configure --prefix=/home/pi/gcc/results.20210516 \
--disable-multilib \
--disable-werror \
--with-pkgversion=$HASH \
--enable-checking=yes \
--enable-languages=c,c++,fortran \
--with-cpu=cortex-a72 \
--with-fpu=neon-fp-armv8 \
--with-float=hard \
--build=arm-linux-gnueabihf \
--host=arm-linux-gnueabihf \
--target=arm-linux-gnueabihf
sed 's/-O2/-O3 -march=native/' < Makefile > Makefile.tmp
diff Makefile Makefile.tmp
mv Makefile.tmp Makefile
Host machine is a raspberry pi 3B+. It is entirely possible the configure
is not quite optimal, although it seems to work.
The command line I used is
$ /home/pi/gcc/results.20210516/bin/gcc -c
gcc.target/aarch64/simd/vgetq_lane_s64_indices_1.c
The bug still seems to occur in yesterday's compiler.
