** Description changed: [Impact] This is needed for some new AMD RDNA4 platforms that require the newer llvm for runtime shader compilation. Skipping oracular, as it is going to be EOL soon. - - Note that llvm-toolchain-20 needs to be built twice on noble, first without llvm-spirv-20 which doesn't exist yet, and then after spirv-llvm-translator-20 has built, it's built a second time *with* llvm-spirv-20 which is needed to build libclc-20 which Mesa needs. + Note that llvm-toolchain-20 needs to be built twice on noble, first + without llvm-spirv-20 which doesn't exist yet, and then after spirv- + llvm-translator-20 has built, it's built a second time *with* llvm- + spirv-20 which is needed to build libclc-20 which Mesa needs. [Test case] Check that drivers that require llvm still work, including swrast (llvmpipe), radeonsi. + Test with normal desktop usage, glxgears, glmark2, Unigine demos. That + should give enough confidence. + [Where things could go wrong] The new llvm version might result in buggy behaviour with the swrast/radeonsi drivers.
