Also, this logic looks troublesome: 42 .if empty(TOOLSDIR) || !exists(${TOOLSDIR}/usr/bin/clang-tblgen) 43 .if ${MACHINE} == "host" && defined(BOOTSTRAPPING_TOOLS) 44 .if !empty(LEGACY_TOOLS) && exists(${LEGACY_TOOLS}/usr/bin/tblgen) 45 TOOLSDIR= ${LEGACY_TOOLS} 46 .endif 47 .endif 48 .if ${MK_STAGING} == "yes" && exists(${STAGE_HOST_OBJTOP:Uno}/usr/bin/tblgen) 49 TOOLSDIR= ${STAGE_HOST_OBJTOP} 50 .endif 51 .if exists(${LEGACY_TOOLS:Uno}/usr/bin/tblgen) 52 TOOLSDIR= ${LEGACY_TOOLS} 53 .endif 54 .endif 55 TOOLSDIR?= 56 .if !empty(TOOLSDIR) && exists(${TOOLSDIR}/usr/bin/clang-tblgen) 57 TBLGEN= ${TOOLSDIR}/usr/bin/tblgen 58 CLANG_TBLGEN= ${TOOLSDIR}/usr/bin/clang-tblgen 59 .endif 60 TBLGEN?= tblgen 61 CLANG_TBLGEN?= clang-tblgen This kind of complexity matched something that I simplified at $work due to build races… Guess what happens when I use a proper clang-tblgen? $ make all /usr/obj/home/ngie/git/freebsd/src/usr.bin/clang/clang-tblgen/clang-tblgen -gen-arm-neon -d arm_neon.d -o arm_neon.h /home/ngie/git/freebsd/src/lib/clang/include/../../../contrib/llvm/tools/clang/include/clang/Basic/arm_neon.td $ Voila. So this is happening because it’s using clang-tblgen from the build host somehow, which is not able to process the .td files. Thanks! -NGie
