test: use testlib (another bunch). Apply sed with: 1s,^// $G $D/$F.go && $L $F.$A && ./$A.out \|\| echo.,// run, 1s,^// $G $D/$F.go \|\| echo.,// compile, R=golang-dev, rsc CC=golang-dev https://golang.org/cl/5656099 2012-02-18 14:15:42 -07:00			`// run`
gc: Don't pollute the xmethod list with non-methods. Fixes #2355. I have a test, but not sure if it's worth adding. Instead i've made the patching-over in reflect.c methods more fatal and more descriptive. R=rsc CC=golang-dev https://golang.org/cl/5302082 2011-11-03 10:51:15 -06:00
