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).
