We finally were able to finish the sync with the Rust compiler and now support the types f16 and f128!
I had a lot of stuff going on lately in my private life, so I wasn't able to work as much as I wanted on rustc_codegen_gcc. Hopefully, it should be back to normal after my vacation.
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.
