Shader compilers mostly use LLVM even though runtime is a constraint, if the pattern is common enough it’s definitely easy to match (it’s just two intrinsics after all) meaning you can do it for cheap in instcombine which you’re going to be running anyway
I’d expect most vendors do, at least in their closed source drivers.
You could also check in the mesa project if this is implemented but it’s definitely possible to do
“Additionally, participants can easily contribute photos and videos to a dedicated Shared Album within each invite to help preserve memories and relive the event.”
This sounds like a great feature. Post event photo sharing is always a bit of a mess.
Another way to explore floating point representation can also be to compare rounding modes, as this can impact a lot of what is generated for floating point operations. Most systems are round to nearest even, but round to zero, round towards positive and round towards negative also exist.
Bonus points if you also check results for x87 floats.
