In addition to those, on amd64 there are two other sets of .s files currently assembled by GNU as: * i386 boot components (stand/i386/{btx,kgzldr,libi386,mbr,pmbr}) * amd64 linuxulator (sys/amd64/linux{,32}) On i386 there are some others: * kernel (sys/i386/i386) * i386 linuxulator (sys/i386/linux) * dtrace tests (cddl/contrib/opensolaris/cmd/dtrace/test/tst/i386) * vm86 test tool (tools/test/vm86) (Other architectures not yet investigated.)
