First, a question: what are the math functions that should be used for DFmode
on sh with -m2e? For example, what function should we use for copysign(DFmode,
DFmode): is that copysignl?
After talking about it on IRC...
- this is a 4.3 regression, but the underlying problem is present since
gfortran was created
- targets with DOUBLE_TYPE_SIZE != 64 aren't so common
- even if we fix the front-end issue, we might have plenty of failures in the
testsuite because the testsuite widely uses 64-bit floating-points types, for
which we might not have math functions...
