    cmd/link: reject non-package main toplevel.a file, remove dead code · c7b1ef99
    Russ Cox authored
    The test for non-package main top-level inputs is done while parsing
    the export data. Issue #13468 happened because we were not parsing
    the export data when using compiler-generated archives
    (that is, when using go tool compile -pack).
    
    Fix this by parsing the export data even for archives.
    
    However, that turns up a different problem: the export data check
    reports (one assumes spurious) skew errors now, because it has
    not been run since Go 1.2.
    (Go 1.3 was the first release to use go tool compile -pack.)
    
    Since the code hasn't run since Go 1.2, it can't be that important.
    Since it doesn't work today, just delete it.
    
    Figuring out how to make this code work with Robert's export
    format was one of the largest remaining TODOs for that format.
    Now we don't have to.
    
    Fixes #13468 and makes the world a better place.
