* rts: RetainerSet: Remove obsolete fist/second-approach choiceDaniel Gröber2019-09-221-27/+2
| | | | | | | | | | | | | In the old code when DEBUG_RETAINER was set, FIRST_APPROACH is implied. However ProfHeap.c now depends on printRetainerSetShort which is only available with SECOND_APPROACH. This is because with FIRST_APPROACH retainerProfile() will free all retainer sets before returning so by the time ProfHeap calls dumpCensus the retainer set pointers are segfaulty. Since all of this debugging code obviously hasn't been compiled in ages anyways I'm taking the liberty of just removing it. Remember guys: Dead code is a liability not an asset :)
* eventlog: Add biographical and retainer profiling tracesMatthew Pickering2019-09-171-1/+1
| | | | | | | | | | This patch adds a new eventlog event which indicates the start of a biographical profiler sample. These are different to normal events as they also include the timestamp of when the census took place. This is because the LDV profiler only emits samples at the end of the run. Now all the different profiling modes emit consumable events to the eventlog.

* rts: Replace `nat` with `uint32_t`Erik de Castro Lopo2016-05-051-4/+4
| | | | | | | | | | | | The `nat` type was an alias for `unsigned int` with a comment saying it was at least 32 bits. We keep the typedef in case client code is using it but mark it as deprecated.

* rts: add Emacs 'Local Variables' to every .c fileAustin Seipp2014-07-281-0/+8
| | | | | | | | This will hopefully help ensure some basic consistency in the forward by overriding buffer variables. In particular, it sets the wrap length, the offset to 4, and turns off tabs. Signed-off-by: Austin Seipp <austin@well-typed.com>

* Declare RTS-private prototypes with __attribute__((visibility("hidden")))Simon Marlow2009-08-051-0/+4
| | | | | | | | | | This has no effect with static libraries, but when the RTS is in a shared library it does two things: - it prevents the function from being exposed by the shared library - internal calls to the function can use the faster non-PLT calls, because the function cannot be overriden at link time.
* Reorganisation of the source treeSimon Marlow2006-04-071-0/+201
Most of the other users of the fptools build system have migrated to Cabal, and with the move to darcs we can now flatten the source tree without losing history, so here goes. The main change is that the ghc/ subdir is gone, and most of what it contained is now at the top level. The build system now makes no pretense at being multi-project, it is just the GHC build system. No doubt this will break many things, and there will be a period of instability while we fix the dependencies. A straightforward build should work, but I haven't yet fixed binary/source distributions. Changes to the Building Guide will follow, too.
