-mfpu=neon is also unnecessary on aarch64: $ clang -target aarch64-unknown-freebsd12.0 -mfpu=neon -c test.c clang: warning: argument unused during compilation: '-mfpu=neon' [-Wunused-command-line-argument] $ aarch64-unknown-freebsd12.0-gcc -mfpu=neon -c test.c aarch64-unknown-freebsd12.0-gcc: error: unrecognized command line option '-mfpu=neon'
-march=armv7-a seems wrong even for armv6 in case user defines CPUTYPE=thunderx (or armv8-a) via make.conf.
(In reply to Jan Beich from comment #2) > CPUTYPE=thunderx Oops, wrong example. Cavium ThunderX doesn't implement aarch32.

strejda informed me that the patch for building the neon bits of vc4 was only meant to be used on armv6
