-ffp-contract=<value>   Form fused FP ops (e.g. FMAs): fast

How can I enable FMA instructions with LDC?

I am sorry but this option is currently not implemented. :-(

I think you refering to ldc.gccbuiltins_x86.di.

Hm, yes, not Intel calling conventions, but it does actually list 
vfma near line 700.

So the OP might want to try those?
