The branch main has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=ab80f0b21fbb9c44d40e6f7a99090188f4ed2f71 commit ab80f0b21fbb9c44d40e6f7a99090188f4ed2f71 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2023-02-25 15:25:57 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2023-02-26 14:56:07 +0000 Ensure .inc files are regenerated when llvm/clang tblgen binaries change When doing a fully incremental build (with WITHOUT_CLEAN enabled), from a commit before llvm 15 was merged (3264f6b88fce), to a commit after that, a number of .inc files were not regenerated. This could lead to unexpected compilation errors when these .inc files were included from llvm-project sources, similar to: In file included from /usr/src/contrib/llvm-project/clang/lib/CodeGen/CGBuiltin.cpp:8268: /usr/obj/usr/src/amd64.amd64/lib/clang/libclang/clang/Basic/arm_mve_builtin_cg.inc:279:18: error: no matching constructor for initialization of 'clang::CodeGen::Address' Address Val2 = Address(Val1, CharUnits::fromQuantity(2)); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Work around this by making the .inc files dependent on the tblgen binary used for generating them. E.g., we can relatively safely assume that if the binary gets updated, the .inc files must also be updated. (Although this is not 100% optimal, the gain by complicating things even more is probaby not worth the effort.)
