# It is important that CFLAGS at least specifies some optimisation,

# and so be unnecessarily large. (The build deduplicates identical
# system call description, but only references to them, not their
# instantiations (which have static storage), for that it it relies
# on compiler optimisation.)
# If you know that the compiler has __builtin_ffsll([unsigned] long long int)
# which returns the index, plus 1, of the least significant set bit
# or 0 for 0, you can add -DHAVE_BUILTIN_FFSLL to CPPFLAGS; if you
# are using GCC>=3.4 or clang>=5, this is added automatically.

# Uncomment this limit supported architectures. You will find which
# architectures are support in Makefile (don't add anything else).
# If you uncomment this without editing it ('!=' means it will execute
# that text behind it as a shell commend; change to '=' to list
# manually), the architecture you are running on, and modes
# (e.g. i386 and x32 on amd64, however if the kernel is built to
# support them)[1], its supports, will be selected.
# [1] Change 'true' to 'false' to exclude them, or remove 'true'
# to support even ones that the kernel is not compiled to support
# You can also limit supported architectures on an per-OS basis, by
# setting SUPPORTED_${NAME_OF_OS}_ARCHES; you will find the list of
# support architectures in ${name-of-os}/${name-of-os}-support.mk,
# however architectures not support in libsyscalls's core may be listed;
# do not add anything that is not supported by both libsyscalls's core
# and it's OS support
# This file is included multiple times, don't do anything weird
