| # 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'. |
