In fact, from all documents that I can found about n32, it seems that long == pointer == 32bit. This is mentioned in the MIPSpro N32 ABI Handbook and in the MIPS Tech document MD00305 'MIPS ABIs Described'.
The only strange thing for n32 is that register_t is 64bit, and vm_paddr_t is similar to PAE. > In particular, sizeof(long) == 4, according to the AMD64 ABI Draft 0.99.8, > which includes both LP64 and ILP32 (x32) ABI description. > _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
