+ This is needed for some new AMD RDNA4 platforms that require the newer
+ llvm for runtime shader compilation.
+
+ [Test case]
+
+ Check that drivers that require llvm still work, including swrast
+ (llvmpipe), radeonsi.
+
+ [Where things could go wrong]
+
+ The new llvm version might result in buggy behaviour with the
+ swrast/radeonsi drivers, but the llvm version we have in plucky has
+ already received some bugfixes and has been tested to be good by AMD.
