From 40280c6f69bdccc21074257818fd4b37b5976679 Mon Sep 17 00:00:00 2001 From: R?my Oudompheng Date: Mon, 15 Sep 2014 18:31:47 +0200 Subject: cmd/gc: don't walk static nodes generated by anylit. During anylit run, nodes such as SLICEARR(statictmp, [:]) may be generated and are expected to be found unchanged by gen_as_init. In some walks (in particular walkselect), the statement may be walked again and lowered to its usual form, leading to a crash. Fixes issue 8017. Fixes issue 8024. Fixes issue 8058.
