The source project of this merge request has been removed.

Adrian Bunk requested to merge (removed):master into master Jan 20, 2023

@edd This fixes https://bugs.debian.org/1024012 (autopkgtest failure in r-cran-xts)

It does cost some performance on i386 to workaround the x87 excess precision with -ffloat-store, but if anyone who cares about FPU performance in R is still using it on i386 in the year 2023 then the latter is the problem. OTOH, this avoids i386-specific maintainer work in R packages where upstream tests expect exact results and fail on the excess precision.
