pass the correct -Dxxx_HOST_ARCH and -Dxxx_HOST_OS to hsc2hs; Fixes #7761. Patch from Stephen Blackheath.
5:07 PM Changeset in base [93a4bda]data-proxydbcsghc-7.8 by Ian Lynagh <ian@…>
Build fix for iOS; fixes #7759 Patch from Stephen Blackheath. The issue here is that the #defines EVFILT_READ and EVFILT_WRITE have the values -1 and -2. The original code translates that to filterRead = Filter -1 which is wrong Haskell and fails to compile. The modified code produces the correct code filterRead = Filter (-1)

Use a pthread-based implementation of Itimer.c on iOS Patch from Stephen Blackheath. timer_create doesn't exist and setitimer doesn't fire on iOS, so we're using a pthreads-based implementation. It may be to do with interference with the signals of the debugger. Revisit. See #7723.
4:41 PM Changeset in base [31153f1]data-proxydbcsghc-7.8 by Ian Lynagh <ian@…>
Implement faster System.Timeout.timeout for the threaded RTS. The basic idea is to use the Timer Manager rather than spawning an auxilliary thread to handle timeouts; this was proposed by Bas van Dijk two years ago (#4963), and recently by Herbert Valerio. The key idea to make this work is to spawn an auxilliary thread for the delivery of the Timeout exception. This idea as well as most of the code is due to Akio Takano.

Merge b737a4 into the 7.6 branch, curing Trac #7748 The caching of goals in the constraint solver led to a equality-constraint loop even in a really simple program! commit b737a45391201fd475b89227ed1d7c9b72b24eea Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Fri Aug 31 10:05:03 2012 +0100 More simplifications to the constraint solver * inert_solved becomes dictionaries-only, inert_solved_dicts * inert_solved_dicts is used only to cache the result of uses of a top level instance declaration, just like inert_solved_funeqs * That in turn simplifies xCtFlavor and rewriteCtFlavor, because they no longer need a "should I cache" parameter. (Moreover the settings for this parameter were very subtle; it's easy to get loops if you cache too much. Caching only top-level instance uses is much safer, and eliminates all these subtle cases.)

Fix the dynflags consistency code It was checking to see whether the hscTarget is HscC or HscLlvm, and changing it to HscC otherwise. But this meant that as well as rejecting HscAsm, it also rejected HscInterpreted and HscNothing. Now we just check whether it's HscAsm.

Make explicit that there can be only one entry point per cmm procedure on Darwin/PPC, because of splitting. x86 should be treated the same way, I'll come back to that later.

ignore RealWorld in size_expr; flag to keep w/w from creating sharing size_expr now ignores RealWorld lambdas, arguments, and applications. Worker-wrapper previously removed all lambdas from a function, if they were all unused. Removing *all* value lambdas is no longer allowed. Instead (\_ -> E) will become (\_void -> E), where it used to become E. The previous behavior can be recovered via the new -ffun-to-thunk flag.

Fix segfaults on SELinux machines; fixes #7629 Patch from wgmitchener. From the ticket: The two addresses (adjustorStub and code) contain the same memory (double-mapped), but one is writable while the other is executable. This is how libffi works around the SELinux restrictions. On non-SELinux systems the code and data addresses are probably the same.

This changes fixes a bad error in canonicalisation, concerning kind equality We care careful not to construct a canonical equality whose LHS and RHS have incompatible kinds. (This is one of the invariants of a canonical equality.) See Note [Equalities with incompatible kinds]. However, what I had not dealt with is when LHS and RHS *look* as if they have different kinds, but after zonking they become the same. Bad! (This led to an ASSERT failure in the test for Trac #7176.)

Change how we handle libffi I think overall the new approach is simpler. Rather than unpacking the libffi.a and putting the .o files into our libHSrts.a, we just use the libffi.a. This change also means that when compiling programs for the dyn way, they get explicitly linked against libffi.so (rather than relying on librts.so being linked against it). This might fix a problem on FreeBSD, where programs cannot find libffi.so.
