Howdy all,

Would anyone like to team up on getting ARM64 support into GHC?

Cheers

Subject: [Haskell-iPhone] Screwy Float values (Double fine,
	not rounding errors)
Message-ID: <CANzGtqcEWuWBMQQ449XeTQuTer6Cxv68TTKh-xf7hes3q=ARoA@mail.gmail.com>

Hi all,

I've been noticing some strange Float behaviour (not rounding errors
but totally erroneous values for non-pathological values).

It seems to be a manifestation of GHC ticket #9125 which was reported
from a Raspberry Pi (arm) version.

A quick example:

> print (29.0 :: Float)

gives

> 2109.0

There is more detail at https://ghc.haskell.org/trac/ghc/ticket/9125#comment:1

Has anyone else seen this?  I'm running a compiled-from-source-tarball
7.8.3 as I couldn't get past the dreaded 'illegal instruction:4'
binary installation bug.  Simulator and device behave the same.

Thanks.

Hi Murray,

I guess I'm using Doubles in my project so I hadn't seen this -- I'll give
it a try as soon as I can!

I assume you saw it already but I had some luck getting past illegal
instruction: 4 as semi-chronicled in here
https://github.com/ghc-ios/ghc-ios-scripts/issues/4

Best
Luke
