Could you please point to the relevant source code for these? From what I could find here, this doesn’t seem implemented for the LLVM backend either.

If VFP uses target-specific intrinsics, there’s a chance that this doesn’t work correctly in the GCC backend yet since our auto-generated mapping we have needs many adjustments and we only added the adjustments for x86-64.

Good. I’ll attempt to do that for the next update.

Do you mean the performance of the tests themselves? If so, how would you suggest that I measure this? By just comparing the execution time?
