Doesn't __mips64__ imply 64 bit wide pointers?
__mips64__ is whatever the build system of cln likes it to be, note the triling underscores. The compiler predefines __mips__ (always), and __mips64 when it uses 64bit wide registers (i.e. with -mabi=n32 or -mabi=64). The pointer width depends on the ABI. o32 ABI and n32 ABI share the same C type widths (they are ILP32). long long is mapped to a register pair in o32, and to a single register in n32. n64 is LP64. Debian currently uses exclusively o32 ABI. Thiemo -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
