# Generate the list of SYS_* macros for the system calls (__NR_* macros).

# If there is more than one syscall list for different architecture
# variants, the CPU/Makefile defines abi-variants to be a list of names
# for those variants (e.g. 32 64), and, for each variant, defines
# abi-$(variant)-options to be compiler options to cause <asm/unistd.h>
# to define the desired list of syscalls and abi-$(variant)-condition to
# be the condition for those options to use in a C #if condition.
# abi-includes may be defined to a list of headers to include
# in the generated header, if the default does not suffice.
#
# The generated header is compiled with `-ffreestanding' to avoid any
# circular dependencies against the installed implementation headers.
# Such a dependency would require the implementation header to be
# installed before the generated header could be built (See bug 15711).
# In current practice the generated header dependencies do not include
# any of the implementation headers removed by the use of `-ffreestanding'.
