    • PR c++/93033 - incorrect tree node sharing with array init. · 8b5d34fc 
      The split_nonconstant_init piece is the only one necessary to fix the
testcase, but it occurred to me that we might as well not split when
-fno-exceptions.

	* typeck2.c (split_nonconstant_init): Unshare non-decl.
	* cp-gimplify.c (cp_gimplify_init_expr): Only split if -fexceptions.

    • gdbinit.in: call a function with "call", not "set" · 582097cb 
      Calling a function foo in gdb as "set foo()" results in a warning.
Disregarding, it looks wrong to call a function with "set". Let's use
"call" instead.

    • libstdc++: Only use std::compare_three_way when concepts are supported · b4e70137 
      Clang now supports three-way comparisons. That causes both overloads of
std::lexicographical_compare_three_way to be defined, but the second one
uses std::compare_three_way which depends on concepts. Clang does not
yet support concepts, so the second overload should also depend on
__cpp_lib_concepts.

	* include/bits/stl_algobase.h (lexicographical_compare_three_way):
	Only define four-argument overload when __cpp_lib_concepts is defined.

    • compiler, runtime, reflect: generate hash functions only for map keys · 10172a64 
          
    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.

    • compiler: split writing of equal and hash functions for types · 9279b5ba 
          
    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.
