Subject: [Bug math/15487] math tests fail with older compilers on i386
Date: Fri, 17 May 2013 19:43:00 -0000	[thread overview]
Message-ID: <bug-15487-131-iOTh8jswMU@http.sourceware.org/bugzilla/> (raw)

My suspicion is that this relates to differences in when each compiler 
uses excess precision, given that it's only for 32-bit and only for float 
and double not long double.

This does illustrate that when we regenerate the x86 / x86_64 ulps from 
scratch (which I think we should do at the start of the release freeze) it 
will be desirable to have not just people with different processors but 
also people with different GCC versions running the tests and adding ulps 
they see but other people don't.
