cmd/go: go1.4 tool breaks compatibility with gcc 4.9 #9062
Labels

This should be prominently declared on the website somewhere. Right now it's not mentioned at all, and is a big departure from the way the previous go tool/gccgo interactions worked (where the go tool was basically backwards compatible). Plus, when you try this combination (which, btw, is the only possible combination right now w/ 1.4), the errors that you get are really really obscure (missing a function signature during tests). If go 1.4 does not support gccgo 4.9, there should be a better error message about the incompatibility when you try it. |
