Subject: [PATCH] Disable unboxed arrays on big-endian
|
|
|
|
Unboxed arrays are broken on big-endian architectures, see
|
|
https://gitlab.haskell.org/ghc/ghc/-/issues/16998 for details.
|
|
This patch makes the use of unboxed arrays conditional on
|
|
little-endian architecture.
|
|
|
|
Fixes #673
