...- A default fpmath setting can be supplied to IRBuilder, which will then apply it to all floating point operations. It is also possible to specify specific fpmath metadata when creating an operation. Ciao, Duncan. -------------- next part -------------- A non-text attachment was scrubbed...

Thanks for the updates! Minor comments: + if (!Accuracy) + // If it's not a floating point number then it must be 'fast'. + return HUGE_VALF; Can we add an assert instead of a comment? It's just as documenting and will catch any goofs. + // If it's not a floating point number then it must be 'fast'. + return !isa<ConstantFP>(MD->getOperand(0));
