From 801a9d9a0c32f0a8db43f145e71b53f11a02b7e2 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Tue, 10 Mar 2020 13:31:15 -0400 Subject: [PATCH] test/codegen: mention in README that tests only run on Linux without -all_codegen This took me a while to figure out. The relevant code is in test/run.go (note the "linux" hard-coded strings): var arch, subarch, os string switch { case archspec[2] != "": // 3 components: "linux/386/sse2" os, arch, subarch = archspec[0], archspec[1][1:], archspec[2][1:] case archspec[1] != "": // 2 components: "386/sse2" os, arch, subarch = "linux", archspec[0], archspec[1][1:] default: // 1 component: "386" os, arch, subarch = "linux", archspec[0], "" if arch == "wasm" { os = "js" } } Change-Id: I92ba280025d2072e17532a5e43cf1d676789c167 Reviewed-on: https://go-review.googlesource.com/c/go/+/222819 Reviewed-by: Keith Randall --- test/codegen/README | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/test/codegen/README b/test/codegen/README index d6b8cf5b32..b803fe585f 100644 --- a/test/codegen/README +++ b/test/codegen/README @@ -16,8 +16,10 @@ step of the top-level test/run.go suite, called "asmcheck".
