* guix/transformations.scm (package-tuned-for-psabi,
multituned-package): New variables.
Change-Id: I09ac7ae9fc2bcd9aa712b3c30fef807bc7d55895
---
This allows wrapping a package definition in multituned-package, ie:
(define-public opus
(multituned-package
(package
...)))
I'm not sure where to go with this patch from here. This will provide
the psabi libraries for x86_64 and powerpc64le so they get most of the
benefits from tuning for the architecture but without needing to specify
which architecture to tune for. It should also provide a nice boost for
guix packs and docker images and the like.
The downside with using this by default is the larger package size due
to the extra versions of the libraries, and if it is used then the
regular --tune is disabled for that package.
I think adding it as a '--tune=generic' or '--tune=psabi' would be a
nice way to use it.
