I think 8.0 requires llvm 3.7 and only supports that version. Are we still planning to bundle opt and LLC in the final release ?<span></span><br><br>On Wednesday, January 13, 2016, George Colpitts <<a

The GHC Team is very pleased to announce the first release candidate of<br>
the Glasgow Haskell Compiler 8.0.1 release. Source and binary<br>
distributions as well as the newly revised users guide can be found at<br>
<br>
<a href="http://downloads.haskell.org/~ghc/8.0.1-rc1/" rel="noreferrer" target="_blank">http://downloads.haskell.org/~ghc/8.0.1-rc1/</a><br>
<br>
This is the first in a series of release candidates which will allow us<br>
to get wider testing of the significant changes that have occurred since<br>
the 7.10 series. These include,<br>
<br>
* the TypeInType extension, which unifies types and kinds allowing for<br>
promotion of more Haskell constructs to the type-level<br>
<br>
* the introduction of type application in source programs<br>
<br>
* support for recursive superclass relationships<br>
<br>
* support for Applicative do notation<br>
<br>
* introduction of the DuplicateRecordFields language extension<br>
<br>
* a rewritten and substantially more thorough pattern match checker<br>
<br>
* the introduction of injective type classes<br>
<br>
* introduction of the Strict and StrictData language extensions,<br>
allowing modules to be compiled with strict-by-default evaluation<br>
of bindings<br>
<br>
* the ability to run the GHCi interpreter in a separate process,<br>
allowing a callstacks in GHCi, easier integration with tooling, and<br>
more<br>
<br>
and much more.<br>
<br>
Changes of this magnitude will invariably bring bugs. This release<br>
candidate in particular is known to suffer from a few significant issues<br>
which are being actively worked upon,<br>
<br>
* The new -XInjectiveTypeFamilies language extension will likely be<br>
renamed to -XTypeFamilyDependencies<br>
<br>
* #11120: Type representations are missing for some types and promoted<br>
constructors<br>
<br>
* #11334: Solving for Typeable (Proxy :: Proxy 'Compose) fails<br>
<br>
* #11276: Pattern checker performance can degrade significantly in<br>
presence of pattern matches with guards<br>
<br>
* #11405: Type-level skolem-escape check fails incorrectly<br>
<br>
* #11414: Use of -XStrict results in compiler abort<br>
<br>
* #11379: Instance solver fails to terminate<br>
<br>
* #11419: Haddock documentation is currently not included in the binary<br>
distributions (and hence is missing on <a href="http://downloads.haskell.org" rel="noreferrer" target="_blank">downloads.haskell.org</a>)<br>
<br>
* #11370: -Wredundant-constraints being included in -Wall breaks<br>
the three-release compatibility policy<br>
<br>
In the coming weeks we will continue to iterate on these issues. We will<br>
also look at Trac tickets marked with "highest" priority on the release<br>
status page [2].<br>
<br>
If you have a ticket that you would like to see addressed that does not<br>
meet one of these criteria, please bring this to our attention.<br>
Likewise, if you encounter an issue please open a ticket if one does not<br>
already exist.<br>
<br>
Also note that we currently cannot offer 32-bit Windows builds due to<br>
breaking changing in a recent Windows 10 upgrade. We'll work to<br>
resolve this before the 8.0 release but please let us know if this poses<br>
a significant problem for you.<br>
<br>
Cheers,<br>
<br>
