* RTS tidyup sweep, first phaseSimon Marlow2009-08-021-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first phase of this tidyup is focussed on the header files, and in particular making sure we are exposinng publicly exactly what we need to, and no more. - Rts.h now includes everything that the RTS exposes publicly, rather than a random subset of it. - Most of the public header files have moved into subdirectories, and many of them have been renamed. But clients should not need to include any of the other headers directly, just #include the main public headers: Rts.h, HsFFI.h, RtsAPI.h. - All the headers needed for via-C compilation have moved into the stg subdirectory, which is self-contained. Most of the headers for the rest of the RTS APIs have moved into the rts subdirectory. - I left MachDeps.h where it is, because it is so widely used in Haskell code. - I left a deprecated stub for RtsFlags.h in place. The flag structures are now exposed by Rts.h. - Various internal APIs are no longer exposed by public header files. - Various bits of dead code and declarations have been removed - More gcc warnings are turned on, and the RTS code is more warning-clean. - More source files #include "PosixSource.h", and hence only use standard POSIX (1003.1c-1995) interfaces. There is a lot more tidying up still to do, this is just the first pass. I also intend to standardise the names for external RTS APIs (e.g use the rts_ prefix consistently), and declare the internal APIs as hidden for shared libraries.
* FIX #1955: confusion between .exe.hp and .hp suffixes for heap profilesSimon Marlow2008-05-191-5/+20
| | | | Now we use <prog>.hp and <prog>.prof consistently.
* FIX #2234: don't generate <prog>.prof unless we're going to put something in itSimon Marlow2008-05-121-27/+37

* new RTS flag: -V to modify the resolution of the RTS timerIan Lynagh2006-09-051-3/+5
| | | | | | | | | Fixed version of an old patch by Simon Marlow. His description read: Also, now an arbitrarily short context switch interval may now be specified, as we increase the RTS ticker's resolution to match the requested context switch interval. This also applies to +RTS -i (heap profiling) and +RTS -I (the idle GC timer). +RTS -V is actually only required for increasing the resolution of the profile timer.
* #807: Removed double fclose of prof_fileIan Lynagh2006-07-081-2/+0
| | | | | prof_file was being fclose'd in both gen_XML_logfile and hs_exit, leading to glibc complaining of a double free.
* New tracing interfaceSimon Marlow2006-06-081-5/+6
| | | | | | | | A simple interface for generating trace messages with timestamps and thread IDs attached to them. Most debugging output goes through this interface now, so it is straightforward to get timestamped debugging traces with +RTS -vt. Also, we plan to use this to generate parallelism profiles from the trace output.

* Reorganisation of the source treeSimon Marlow2006-04-071-0/+941
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.
