5457	Please whitelist architectures supporting registered builds	nomeata		"Hi,

the {{{debian/rules}}} file contains this snippet:

{{{
ifneq (,$(findstring $(DEB_HOST_ARCH), i386 amd64 kfreebsd-i386 kfreebsd-amd64 powerpc))
        echo ""GhcUnregisterised=NO"" >> mk/build.mk
else
        echo ""GhcUnregisterised=YES"" >> mk/build.mk
endif
}}}

which decides whether to do a registered or unregistered build. Obviously, three is nothing Debian specific about it, and it seems to me as if the ghc build system should already know whether a given architecture supports registered builds or not. In fact, in {{{mk/config.mk}}}, I see this code:
{{{
ifneq ""$(findstring $(HostArch_CPP), alpha hppa)"" """"
GhcUnregisterised=YES
else
GhcUnregisterised=NO
endif
}}}

Maybe either this list could be extended or, probably more useful, the logic inverted an all architectures _with_ support for registered builds entered.

BTW, {{{OsSupportsGHCi}}} in that file should also include {{{kfreebsdgnu}}}.

Thanks,
Joachim"	feature request	closed	normal		Build System	7.2.1	fixed			Unknown/Multiple	Unknown/Multiple	None/Unknown
