* Drop GHC 7.10 compatibilityRyan Scott2017-08-011-2/+0
| | | | | | | | | | | | | | | | GHC 8.2.1 is out, so now GHC's support window only extends back to GHC 8.0. This means we can delete gobs of code that was only used for GHC 7.10 support. Hooray!

* hschooks.c: Ensure correct header file is includedBen Gamari2016-11-291-1/+8
| | | | | | | | | | | | | | | | Consider the case of building a stage1 compiler. `hschooks.c` will be built by stage0 `ghc` and linked against the `stage0` RTS. Despite this it was #including the stage1 `Rts.h`. There is, of course, no guarantee that this is ABI-compatible with the stage0 RTS and when they diverge Bad Things happen (e.g. bells ringing at inappropriate times in D2699).

* Fix #8754 again.Austin Seipp2014-02-201-1/+14
| | | | | | | | This time, we carefully initialize the GC stats only if they're not already initialized - this way the user can override them (e.g. `+RTS -t --machine-readable`). Signed-off-by: Austin Seipp <austin@well-typed.com>
* Deprecate lnat, and use StgWord insteadSimon Marlow2012-09-071-1/+1
| | | | | | | | | | | | lnat was originally "long unsigned int" but we were using it when we wanted a 64-bit type on a 64-bit machine. This broke on Windows x64, where long == int == 32 bits. Using types of unspecified size is bad, but what we really wanted was a type with N bits on an N-bit machine. StgWord is exactly that. lnat was mentioned in some APIs that clients might be using (e.g. StackOverflowHook()), so we leave it defined but with a comment to say that it's deprecated.

* Time handling overhaulSimon Marlow2011-11-251-0/+4
| | | | | | | | | | | | | | | | | | | | | Terminology cleanup: the type "Ticks" has been renamed "Time", which is an StgWord64 in units of TIME_RESOLUTION (currently nanoseconds). The terminology "tick" is now used consistently to mean the interval between timer signals. The ticker now always ticks in realtime (actually CLOCK_MONOTONIC if we have it). Before it used CPU time in the non-threaded RTS and realtime in the threaded RTS, but I've discovered that the CPU timer has terrible resolution (at least on Linux) and isn't much use for profiling. So now we always use realtime. This should also fix The default tick interval is now 10ms, except when profiling where we drop it to 1ms. This gives more accurate profiles without affecting runtime too much (<1%). Lots of cleanups - the resolution of Time is now in one place only (Rts.h) rather than having calculations that depend on the resolution scattered all over the RTS. I hope I found them all.
* Cleanup sweep and fix a bug in RTS flag processing.Simon Marlow2011-04-121-1/+0
| | | | | | | | | | | | | This code has accumulated a great deal of cruft over the years, this pass cleans up a lot of the surrounding cruft but leaves the actual argument processing alone - so there's still more that could be done. Bug fixed: - ghc_rts_opts should not be subject to the --rtsopts setting. If the programmer explicitly declares options with ghc_rts_opts, they shouldn't also have to accept command-line RTS options to make them work.
