From 939a942ecd5a3afbadb300e6a490d368f5bf5e60 Mon Sep 17 00:00:00 2001 From: Martin Nordholts Date: Tue, 18 Feb 2025 09:47:07 +0100 Subject: [PATCH] Enable `f16` for MIPS It seems as if `f16` works on MIPS now according to my testing on Rust master with LLVM 20, and I was asked to create PRs with my changes. I only tested on the flavour of `mipsel-unknown-linux-gnu` hardware that happens to be available to me, so I can't say anything about other MIPS hardware, but from a casual skimming of the LLVM code ([1], [2]) it seems like `f16` should work on all MIPS hardware. So enable it for all MIPS hardware.
