It didn't work for the original reporter on freebsd-stable@ here: https://lists.freebsd.org/pipermail/freebsd-stable/2018-May/089026.html and for me it still gives: $ make -C /usr/src/sys/modules/aesni gcc -c -O3 -pipe -fno-strict-aliasing -Werror -D_KERNEL -DKLD_MODULE -I. -I/usr/src/sys -fno-common -mno-mmx -mno-sse -msoft-float -ffreestanding -fwrapv -fstack-protector -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -Wmissing-include-dirs -fdiagnostics-show-option -Wno-unknown-pragmas -Wno-uninitialized -finline-limit=8000 -fms-extensions --param inline-unit-growth=100 --param large-function-growth=1000 -mno-align-long-strings -mpreferred-stack-boundary=2 -std=iso9899:1999 -Werror -mmmx -msse -msse4 -maes -mpclmul /usr/src/sys/crypto/aesni/aesni_ghash.c cc1: error: unrecognized command line option "-msse4" cc1: error: unrecognized command line option "-mpclmul" *** Error code 1 Those unrecognized flags were added more than 3 years ago, in r275732, so I assume this has been broken since that time. Maybe nobody built any kernels with gcc for 3 years? :) -Dimitry
