URL: https://github.com/llvm/llvm-project/commit/2bdf5aa5dffffebf6e3b1afe588db990ca58e55c DIFF: https://github.com/llvm/llvm-project/commit/2bdf5aa5dffffebf6e3b1afe588db990ca58e55c.diff LOG: [Driver] Properly report error for unsupported powerpc darwin/macos triples The removal started at https://reviews.llvm.org/D50989 and https://reviews.llvm.org/D75494 removed the Triple support. Without recognizing Darwin triples as Mach-O, we will get assertion error in ToolChains/Darwin.h due to the universal binary mechanism. Fix #47698 --- This requires fixing many misuses of llc -march= and llvm-mc -arch= ( commits 806761a7629df268c8aed49657aeccffa6bca449 and 252c42354eca54274ed7b10c32c73c6937478e8b).
