Not enabled by default generally implies not usable at all for decimal floating point; you generally need at least some support for the ABI, saying what modes are allowed in what registers, etc. - and the current revision of AAPCS doesn't include decimal floating point at all so there is no ABI to follow at present. It seems likely to me that if you enabled decimal floating point on ARM you'd get ICEs. -- Joseph S. Myers jos...@codesourcery.com
