Subject:     compiler: Report unnamed receiver types.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9ddf5f1a2eac0260ad3c1fd363194abe74a00022;p=thirdparty%2Fgcc.git

compiler: Report unnamed receiver types.

    gccgo used to crash when presented with an invalid receiver type in a
    method.  Instead, unnamed receiver types should report an error.

    Fixes golang/go#11557.
