[Bug target/39986] decimal float constant is incorrect when cc1 is a 64-bit binary

[janis at gcc dot gnu dot org]

------- Comment #1 from janis at gcc dot gnu dot org  2009-05-01 18:57 -------
The problem is that in dfp.c, functions encode_decimal* and decode_decimal* use
memcpy from a 32-bit int to a long for 32 bits.  This works fine with -32 where
long is 32 bits, but not for -m64 where long is 32 bits.  I assume that it
magically works fine on little-endian systems like x86_64.

This is not a regression, just a horrible wrong-code bug.

I'm testing a patch.
