# This file contains a pre-compiled version of chacha_vec.c for ARM. This is
# needed to support switching on NEON code at runtime. If the whole of OpenSSL
# were to be compiled with the needed flags to build chacha_vec.c, then it
# wouldn't be possible to run on non-NEON systems.

# EABI attribute 28 sets whether VFP register arguments were used to build this
# file. If object files are inconsistent on this point, the linker will refuse
# to link them. Thus we report whatever the compiler expects since we don't use
