I went back and looked up my old notes from 2016-Jan-18 ( https://lists.freebsd.org/pipermail/freebsd-arm/2016-January/013053.html ) and it indicates that one must use 11.0 -r294031 or later to build clang 3.8.0. The issue is clang 3.8.0 being bigger and needing -mlong-calls compiler options in more places than the older clang 3.7.1 did. Quoting from the 2016-Jan-18 message. . . > The clang 3.8.0 investigation ran into this for building clang and lldb. A quick scan of materials checked out from that branch (my /usr/src is bound to that branch) shows the following as far as what 4 Makefile* or 2 *.mk files list the option someplace: > > > # find /usr/src/ -name .svn -prune -o -name 'Makefile*' -exec grep mlong-calls {} \; -print > > STATIC_CXXFLAGS+= -mlong-calls > > /usr/src/lib/libc++/Makefile > > STATIC_CFLAGS+= -mlong-calls > > /usr/src/lib/csu/arm/Makefile > > CFLAGS+= -mlong-calls > > /usr/src/usr.bin/clang/lldb/Makefile > > CFLAGS+= -mlong-calls > > /usr/src/usr.bin/clang/clang/Makefile > > > > # find /usr/src/ -name .svn -prune -o -name '*.mk' -exec grep mlong-calls {} \; -print > > STATIC_CXXFLAGS+= -mlong-calls > > /usr/src/lib/clang/clang.lib.mk > > CFLAGS+= -G0 -fno-pic -mno-abicalls -mlong-calls > > /usr/src/sys/conf/kmod.mk > > > (That last one is for mips instead of arm and has been around a long time.)
