Hi
I am working on porting Fedora for AArch64 architecture. This means patching many packages and during that time I noticed lot of checks for 32/64-bit architectures.
Most common one is:
%global something 32 %ifarch x86_64 ppc64 s390 %global something 64 %endif
Which can be now replaced to simple:
%global something %{__isa_bits}
And this works fine in Fedora 19 and beyond (including RHEL 7). There are also some other variations of 32/64-bit checks which could be converted.
Can use of %__isa_bits be somehow announced/suggested to developers? Would cut amount of patching needed for each new architecture.
This is basically a good idea, but it'd have a better chance of happening if you could prepare an actual draft text to be included in the Packaging Guidelines.
