Description: Allow unregisterised ghc-8.6 to build newer GHC
|
|||
|
|
Commit af9b744bbf1 introduced a regression stopping existing unregisterised
|
|||
|
|
compilers from being able to compile newer versions of GHC. The problem is
|
|||
|
|
that the bootstrap compiler uses the newer `includes/stg/MiscClosures.h` file
|
|||
|
|
where some defines have been renamed, resulting in the following error:
|
|||
|
|
.
|
|||
|
|
error: ‘stg_atomicModifyMutVarzh’ undeclared (first use in this function); did you mean ‘stg_atomicModifyMutVar2zh’?
|
|||
|
|
.
|
|||
|
|
For more information, see https://gitlab.haskell.org/ghc/ghc/issues/17111.
|
|||
|
|
.
|
|||
|
|
This patch can be removed, once ghc-8.6 is no longer the bootstrap compiler.
