Thanks.
>From gcc\gcc\configure.ac, I see decimal float only enabled on
targets: powerpc*-*-linux* | i?86*-*-linux* | x86_64*-*-linux*
Can I enable decimal float support by simple add
i?86*-*-mingw* | x86_64*-*-mingw*
to the targets list ?
I found gcc implement decimal64 and decimal128 by decNumber, not
by decDouble and decQuad. But in the decNumber performance page:
http://speleotrove.com/decimal/dnperf.html
I see decDouble and decQuad much fast than decNumber, is there any
realization of consideration ?
