HiïI have one more question for bug fix 19550 on N32's mmap64.
After bug fix 19550, N32' mmap64 can handle 2GB<= offset < 4GBïbut it
can not handle 4GB <= offset < 2^44 - 1( offset is off64_t, the last arg
of mmap64)
which is not identical to o32's mmap64. Since mips n32 does not have
__NR_mmap2
syscall, if a O32 mmap64 application is transplanted into N32, do we
need to handle
this in N32's mmap64?
