To Whom It May Concern: I am building FreeBSD 11 stable i386 on an old Pentium 4 machine. The clang/llvm build is just horrific in length, so I am substituting gcc by the appropriate /etc/src.conf defines such as WITHOUT_CLANG, WITHOUT_CLANG_BOOTSTRAP, WITH_GCC, WITH_GCC_BOOTSTRAP. After deleting clang via make delete-old in /usr/src, all of userland builds fine, but the kernel will not build due to the aesni module. The build break is due to compiling /usr/src/sys/crypto/aesni/aesni_ghash.c, which in turn #includes wmmintrin.h, emmintrin.h, and smmintrin.h which are all clang-specific headers. I am rebuilding with MK_CRYPT=no to see if this works around the problem, but it seems like perhaps just this one aesni module should not be built rather than all of CRYPT having to be disabled. This is a post 11.2 BETA3 sync to STABLE as of today, 29 May 2018. Dan
