2020-01-09compiler: don't add composite literal keys to package bindingsIan Lance Taylor5-33/+101
Adding composite literal keys to package bindings gets confusing when it is combined with dot imports. The test case showing the resulting compilation failure is https://golang.org/cl/213899. Fix this by adding a new expression type to hold composite literal keys. We shouldn't see it during lowering if it is a struct field name, because Composite_literal_expression::do_traverse skips struct field names. Or, it should, but that didn't quite work with pointer types so it had to be tweaked. This lets us remove the code that recorded whether an Unknown_expression is a composite literal key.

2020-01-08compiler: fix loopdepth tracking in array slicing expression in escape analysisIan Lance Taylor2-2/+3
In the gc compiler, for slicing an array, its AST has an implicit address operation node. There isn't such node in the gofrontend AST. During the escape analysis, we create a fake node to mimic the gc compiler's behavior. For the fake node, the loopdepth was not tracked correctly, causing miscompilation. Since this is an address operation, do the same thing as we do for the address operator. Fixes golang/go#36404. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/213643 From-SVN: r279984

2020-01-02compiler, runtime, reflect: generate hash functions only for map keysIan Lance Taylor6-161/+106
Right now we generate hash functions for all types, just in case they are used as map keys. That's a lot of wasted effort and binary size for types which will never be used as a map key. Instead, generate hash functions only for types that we know are map keys. Just doing that is a bit too simple, since maps with an interface type as a key might have to hash any concrete key type that implements that interface. So for that case, implement hashing of such types at runtime (instead of with generated code). It will be slower, but only for maps with interface types as keys, and maybe only a bit slower as the aeshash time probably dominates the dispatch time. Reorg where we keep the equals and hash functions. Move the hash function from the key type to the map type, saving a field in every non-map type. That leaves only one function in the alg structure, so get rid of that and just keep the equal function in the type descriptor itself. While we're here, reorganize the rtype struct to more closely match the gc version. This is the gofrontend version of https://golang.org/cl/191198.

2020-01-02compiler: split writing of equal and hash functions for typesIan Lance Taylor7-361/+545
Separate the generation of type equality and hash functions, rather than doing them in a single operation. This is almost entirely a pure refactoring in preparation for generating hash functions only for types that are map keys. The only change in generated code is that for types that are the size of numeric types, but not aligned like numeric types, such as [8]byte, now use standard hash functions. They previously used special-purpose hash functions because they required special-purpose equal functions. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/212842 From-SVN: r279847
