Yes, that sort of thing. For a while there was a higher version required for powerpc64le, and there will be again soon, so that's an example. -- Joseph S.

Something along the lines... - * GCC 6.2 or newer + * GCC 6.2 or newer (For some architectures specific later versions needed) - GCC 6.2 or higher is required. In general it is recommended to use - the newest version of the compiler that is known to work for + GCC 6.2 or higher is required. ARC architecture needs gcc 8.2 or later. + In general it is recommended to use the newest version of the compiler > > An alternative in some cases is increasing the global minimum.

"normal" means "the versions documented in install.texi, node Tools for Compilation, as the minimum for building glibc on most architectures". That node should give comprehensive information on what tool versions are needed to build glibc. If an architecture requires GCC more recent than 6.2, or binutils more recent than 2.25, that needs to be documented there (unless the minimum versions for that architecture are the minimum binutils / GCC versions that supported that architecture at all). An alternative in some cases is increasing the global minimum. Typically the global minimum is a version from a few years ago; if it's been a year since the minimum major GCC version for building glibc was last updated, it may well be reasonable to propose an architecture-independent increase of that version to the next major GCC release, for example. -- Joseph S.

"normal" would the ones mentioned in build-many-glibcs ? The min versions for ARC are over year old already so I don't think it needs mentioning. ___ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc

Any architecture with a higher minimum compiler / binutils version than normal needs it documented in install.texi, with the INSTALL file regenerated. -- Joseph S.
