X-Git-Tag: go1.5beta1~583
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=38631846bf6f5c290bdef15c22a09695fd6018c4;p=gostls13.git

syscall: add explicit build tags

Auto-generated using the following bash script:
for i in z*_*_*.go; do
        goosgoarch=`basename ${i/${i/_*/}_/} .go`
        goos=${goosgoarch/_*/}
        goarch=${goosgoarch/*_/}
        echo $i $goos $goarch
        [ "$goos" = "windows" ] && continue
        sed -i -e "/^package /i\/\/ +build $goarch,$goos\n" "$i"
done
