+# Generate a list of SYS_* macros from the linux __NR macros.
+#
+# Before version 2.6, linux had separate 32-bit and 64-bit MIPS ports,
+# each with its own set of headers.  The ports were merged for 2.6 and
+# this merged port defines the syscalls in a slightly different way.
+# There are therefore three sets of headers that we need to consider:
+#
+#    (1) Headers from the separate 32-bit MIPS port.  They just define
+#	 a single list of __NR macros.
+#
+#    (2) Headers from the separate 64-bit MIPS port.  They unconditionally
+#	 define syscalls for all three ABIs, with o32 syscalls prefixed
+#	 by __NR_O32, n32 syscalls prefixed by __NR_N32 and n64 syscalls
+#	 prefixed by plain __NR.
+#
+#    (3) Headers from the combined port.  They use the _MIPS_SIM macro to
+#	 define the right set of syscalls for the current ABI.  The syscalls
+#	 themselves have no special ABI prefix, but the headers also define:
+#
+#	    __NR_O32_Linux{,_syscalls}
+#	    __NR_N32_Linux{,_syscalls}
+#	    __NR_64_Linux{,_syscalls}
+#
+# In case (1) we just want a simple list of SYS_* macros.  In cases (2)
+# and (3) we want a file that will work for all three ABIs, regardless
+# of which ABI we are currently using.  We also want the file to work
+# if the user later moves from (2) to (3).  Thus the file we create
+# for (2) and (3) has the form:
+#
+#    #if _MIPS_SIM == _ABIN32
+#    # ifdef __NR_N32_open
+#    #  define SYS_n32syscall1 __NR_N32_n32syscall1
+#    #  ...
+#    # else
+#    #  define SYS_n32syscall1 __NR_n32syscall1
+#    #  ...
+#    # endif
+#    #elif _MIPS_SIM == _ABI64
+#    # define SYS_n64syscall1 __NR_n64syscall1
+#    # ...
+#    #else
+#    # ifdef __NR_O32_open
+#    #  define SYS_o32syscall1 __NR_O32_o32syscall1
+#    #  ...
+#    # else
+#    #  define SYS_o32syscall1 __NR_o32syscall1
+#    #  ...
+#    # endif
+#    #endif
+#
+# Here, __NR_N32_open and __NR_O32_open are used to detect case (2)
+# over case (3).  The n64 SYS_* macros can always use the normal
+# ABI-less names.
