test: remove semiocolons. The ken directory is untouched so we have some examples with explicit semis. R=gri CC=golang-dev https://golang.org/cl/2157041 2010-09-04 00:36:13 +00:00			`var x = &main // ERROR "address of\|invalid"`

test: explicitly use variables to avoid gccgo "not used" error I haven't looked at the source, but the gc compiler appears to omit "not used" errors when there is an error in the initializer. This is harder to do in gccgo, and frankly I think the "not used" error is still useful even if the initializer has a problem. This CL tweaks some tests to avoid the error, which is not the point of these tests in any case. R=golang-dev, r CC=golang-dev https://golang.org/cl/5561059 2012-01-22 19:50:45 +00:00			`_ = x`
