Subject: cmd/5g, cmd/8g: fix build
X-Git-Tag: go1.3beta1~706
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=7addda685d9f624479cd2248a86a16b5a810f225;p=gostls13.git

cmd/5g, cmd/8g: fix build

The test added in CL 63630043 fails on 5g and 8g because they
were not emitting the VARDEF instruction when clearing a fat
value by clearing the components. 6g had the call in the right place.

Hooray tests.
