+    Auto merge of #35814 - alexcrichton:armv7-no-neon, r=brson
+
+    rustc: Don't enable NEON by default on armv7 Linux
+
+    One of the primary platforms for the `armv7-unknown-linux-gnueabihf` target,
+    Linux distributions, do not enable NEON extensions by default. This PR disables
+    that feature by defualt but enables the `d16` feature which enables VFP3D16 that
+    distributions do enable.
+
+    Closes #35590

+    Auto merge of #36933 - alexcrichton:less-neon-again, r=eddyb
+
+    rustc: Try again to disable NEON on armv7 linux
+
+    This is a follow-up to #35814 which apparently didn't disable it hard enough. It
+    looks like LLVM's default armv7 target enables NEON so we'd otherwise have to
+    pass `-neon`, but we're already enabling armv7 with `+v7` supposedly, so let's
+    try just telling LLVM that the armv7 target is arm and then enable features
+    selectively.
+
+    Closes #36913
