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