* Revert "rts: add Emacs 'Local Variables' to every .c file"Simon Marlow2014-09-291-8/+0
| | | | This reverts commit 39b5c1cbd8950755de400933cecca7b8deb4ffcd.
* 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>

* rts_isProfiled should be a visible API (fixes T2615(dyn))Simon Marlow2010-09-151-2/+0

* Use StgWord64 instead of ullongIan Lynagh2010-04-211-1/+1
| | | | | | This patch also fixes ullong_format_string (renamed to showStgWord64) so that it works with values outside the 32bit range (trac #3979), and simplifies the without-commas case.

* 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.

* RTS tidyup sweep, first phaseSimon Marlow2009-08-021-18/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* When debugging, have the allocator help us a bitIan Lynagh2006-12-111-0/+3
| | | | | | | We now check for freeing memory that isn't allocated, and overwrite memory we are about to free with 0xaa. It might be nice to also have a flag to control whether the memory actually gets free'd.
* replace stgMallocBytesRWX() with our own allocatorSimon Marlow2006-05-301-3/+0
| | | | | | | | | | | | | | | | | | | | See bug #738 Allocating executable memory is getting more difficult these days. In particular, the default SELinux policy on Fedora Core 5 disallows making the heap (i.e. malloc()'d memory) executable, although it does apparently allow mmap()'ing anonymous executable memory by default. Previously, stgMallocBytesRWX() used malloc() underneath, and then tried to make the page holding the memory executable. This was rather hacky and fails with Fedora Core 5. This patch adds a mini-allocator for executable memory, based on the block allocator. We grab page-sized blocks and make them executable, then allocate small objects from the page. There's a simple free function, that will free whole pages back to the system when they are empty.
* Reorganisation of the source treeSimon Marlow2006-04-071-0/+54
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.
