Re: [PATCH]: Backport PR other/13906 for "fold" checking

Precisely.  I think SPARC/Solaris is not the right platform to enable the 
platform-independent fold checking because...

...it is a big loss when the 2 only testers for a platform don't agree on the 
testing results (and you test more regularly than me).  The results you post 
are essentially useless for me now, given that I cannot assert whether the 
failures are real or not, since nobody else enables fold checking.

IMHO the numerous cycles burned by fold checking should be better used on 
SPARC/Solaris, because they are a _very_ scarce resource nowadays.  You could 
for example enable multilib (-m32/-m64) testing or -fPIC testing again.  
That's what you did a few years ago on your Solaris 7 box and that was quite 
useful; thanks to it, -fPIC support is rock solid in the SPARC back-end.
