* Remove unused global variablesSylvain Henry2020-09-301-4/+0
| | | | | | | | | | Some removed globals variables were still declared in the RTS. They were removed in the following commits: * 4fc6524a2a4a0003495a96c8b84783286f65c198 * 0dc7985663efa1739aafb480759e2e2e7fca2a36 * bbd3c399939311ec3e308721ab87ca6b9443f358
* Remove unsafeGlobalDynFlags (#17957, #14597)Sylvain Henry2020-09-301-1/+3
| | | | | There are still global variables but only 3 booleans instead of a single DynFlags.

* cpp: Use #pragma once instead of #ifndef guardsBen Gamari2017-04-231-4/+1
| | | | | | | | | | | | | | This both says what we mean and silences a bunch of spurious CPP linting warnings. This pragma is supported by all CPP implementations which we support.

* Make globals use sharedCAFMoritz Angermann2016-12-111-9/+18
| | | | | | | | | | | | | | | | | | | Summary: The use of globals is quite painful when multiple rts are loaded, e.g. when plugins are loaded, which bring in a second rts. The sharedCAF appraoch was employed for the FastStringTable; I've taken the libery to extend this to the other globals I could find. This is a reboot of D2575, that should hopefully not exhibit the same windows build issues.

* Second attempt to fix #1185 (forkProcess and -threaded)Simon Marlow2009-11-111-1/+5
| | | | | | | | | | | | Patch 1/2: second part of the patch is to libraries/base This time without dynamic linker hacks, instead I've expanded the existing rts/Globals.c to cache more CAFs, specifically those in GHC.Conc. We were already using this trick for signal handlers, I should have realised before. It's still quite unsavoury, but we can do away with rts/Globals.c in the future when we switch to a dynamically-linked GHCi.
* Tidy up file headers and copyrights; point to the wiki for docsSimon Marlow2009-08-251-0/+5
| | | | | | | I've updated the wiki page about the RTS headers http://hackage.haskell.org/trac/ghc/wiki/Commentary/SourceTree/Includes to reflect the new layout and explain some of the rationale. All the header files now point to this page.
* RTS tidyup sweep, first phaseSimon Marlow2009-08-021-0/+18
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.
