ghc/rts/win32 GetTime.c
Log:
Improvments to time-measurement and stats:
- move all the platform-dependent timing related stuff into
posix/GetTime.c and win32/GetTime.c, with the machine-indepent
interface specified in GetTime.h. This is now used by
Stats.c.
- On Unix, use gettimeofday() and getrusage() by default, falling
back to time() if one of these isn't available.
- try to implement thread-specfic CPU-time measurement using
clock_gettime() on Unix. Doesn't work reliably on Linux, because
the implemenation tries to use the processor TSC, which on an
SMP machine goes wrong when the thread moves between CPUs. However,
it's slightly less bogus that before, and hopefully will improve
in the future.
