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.

f16 and f128

Great!👍🏻 What about FPU and VFP support?

[-] antoyo@programming.dev 1 points 4 months ago

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.
