[llvm-commits] [PATCH][Review request] IEEE quad software emulation library call

[Hatanaka, Akira]

Okay, if that doesn't work, I think I will have to legalize f128 during type legalization.

Is the patch fine as it is now? Or does it need further changes?

Hi Akira,

Ah, probably it will require f128 to be a legal type, yes... On
z/System there is hardware support for f128, so it was not a problem.
Here most probably it won't work...
