# Usage: $0 top_srcdir
#
# This script walks all headers in $top_srcdir/include and makes sure that all
# functions declared tehre are marked as inline or constexpr (which implies
# inline). This makes sure the xsimd headers does not define symbol with global
# linkage, and somehow convey our itnent to have all functions in xsimd being
# inlined by the compiler.
