* cpp: Use #pragma once instead of #ifndef guardsBen Gamari2017-04-23183-742/+191
| | | | | | | | | | | | | | 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.

* ghc: tweak cross-compilation to mingw32Sergei Trofimovich2017-04-231-5/+5
| | | | | | | | | | | | | | | The build failure when cross-compiling from linux to windows looks like: HC [stage 1] ghc/stage2/build/tmp/ghc-stage2.exe Call hs_init_ghc() from your main() function to set these options. /usr/libexec/gcc/i686-w64-mingw32/ld: cannot find -lHSghc-8.3-0 Similar to commit 745032dd02da511067c2939259ed212852187e0f ("rts: tweak cross-compilation to mingw32") decision to split stage2 should be done based based on TargetOS, not HostOS.

* Minor reordering of `#include`s fixing compilation on AIXHerbert Valerio Riedel2017-04-233-7/+7
| | | | | | | This helps ensure that system includes on some more fragile platforms (like e.g. AIX) see a more consistent set of CPP defines, and consequently reduce the risk of conflicting typdefs/prototypes being exposed.
* rts: tweak cross-compilation to mingw32Sergei Trofimovich2017-04-231-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Found the problem on x86_64-linux host where I tried to cross-compile GHC to windows as: $ ./configure --target=i686-w64-mingw32 \ Windres=i686-w64-mingw32-windres \ DllWrap=i686-w64-mingw32-dllwrap As a result build failed as POSIX bits of RTS. For example 'rts/posix/OSMem.c' contains unix-specific mmap() syscalls and constants and thus can't be compiled by i686-w64-mingw32 toolchain. It's caused by the following part of 'rts/ghc.mk': ifeq "$(HostOS_CPP)" "mingw32" ALL_DIRS += win32 else ALL_DIRS += posix endif In our case _CPP variables are defined this way (project.mk): BuildOS_CPP = linux HostOS_CPP = linux TargetOS_CPP = mingw32 RTS should never be built for 'BuildOS' or 'HostOS' as it's always built by ghc-stage1 (targeted at TargetOS). The change is to flip 'HostOS_CPP' to 'TargetOS_CPP' in 'rts/ghc.mk'. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* base: Fix hWaitForInput with timeout on POSIXBen Gamari2017-04-213-12/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | This was previously broken (#13252) by f46369b8a1bf90a3bdc30f2b566c3a7e03672518, which ported the fdReady function from `select` to `poll` and in so doing dropping support for timeouts. Unfortunately, while `select` tells us the amount of time not slept (on Linux anyways; it turns out this is implementation dependent), `poll` does not give us this luxury. Consequently, we manually need to track time slept in this case. Unfortunately, portably measuring time is hard. Ideally we would use `clock_gettime` with the monotonic clock here, but sadly this isn't supported on most versions of Darwin. Consequently, we instead use `gettimeofday`, running the risk of system time changes messing us up.
