It's been a while... I see the CRIS port broke with the time_t-default-to-64-bit change, observable by a few test-cases in the gcc fortran(!) tests failing, regressing when trying a recent newlib. This is a two-part belt-and-suspenders change: adjust the CRIS port gettimeofday syscall (the only one in newlib/CRIS passing a time_t or struct timeval) to handle a userspace 64-bit time_t and secondly default time_t to 32-bit long anyway. I considered making the local "kernel_timeval" copy in _gettimeofday conditional on (userspace) time_t being 64 bits, but thought it not worth bothering with the few move insns. The effect of a 64-bit time_t is however observable as longer simulation time when running the gcc testsuite and as bigger binaries without any actual upside from the larger time_t size, so I thought better make the default for this port go back to being a "long" again. Tested by running the gcc testsuite over the three combinations of two parts of the patch and observing the expected changes. Committed. libgloss: Adjust for syscall and userspace having different time_t or timeval. * cris/linunistd.h (kernel_time_t, kernel_suseconds_t, kernel_timeval): New types. (gettimeofday): Change the type of the first argument to be a pointer to a struct kernel_timeval. * cris/gensyscalls (_gettimeofday): Use an intermediate struct kernel_timeval for the syscall and initialize the result from that.
