Hi John-Mark, Unfortunately this does not work with /usr/bin/gcc (which I still use as /usr/bin/cc on this old IBM T60 laptop due to clang's enormous pestimation on 'make world' and build times. Please fix this ASAP or back it out out of 10-CURRENT as it does not work with /usr/bin/gcc: 1. /usr/bin/gcc cannot handle the "-maes" option. I committed r255440 to address this. 2. /usr/src/sys/modules/aesni/../../crypto/aesni/aesencdec.h:30:23: error: wmmintrin.h: No such file or directory and then a cascade of errors follow. For now, I've sent a patch to re@ for approval to remove the 'aesni' module from the build if not using clang. But the LINT build is still broken with /usr/bin/gcc. > Replace .byte hard coded instructions w/ the proper instructions now > that both clang and gcc support them... Is this out-of-tree latest GCC that supports this? thanks, -- -- David (obrien@FreeBSD.org)
