    • compiler: improve name mangling for packpaths · 34489eb2 
          
    The current implementation of Gogo::pkgpath_for_symbol was written in
    a way that allowed two distinct package paths to map to the same
    symbol, which could cause collisions at link- time or compile-time.
    
    Switch to a better mangling scheme to insure that we get a unique
    packagepath symbol for each package. In the new scheme instead of having
    separate mangling schemes for identifiers and package paths, the
    main identifier mangler ("go_encode_id") now handles mangling of
    both packagepath characters and identifier characters.
    
    The new mangling scheme is more intrusive: "foo/bar.Baz" is mangled as
    "foo..z2fbar.Baz" instead of "foo_bar.Baz". To mitigate this, this
    patch also adds a demangling capability so that function names
    returned from runtime.CallersFrames are converted back to their
    original unmangled form.
    
    Changing the pkgpath_for_symbol scheme requires updating a number of
    //go:linkname directives and C "__asm__" directives to match the new
    scheme, as well as updating the 'gotest' driver (which makes
    assumptions about the correct mapping from pkgpath symbol to package
    name).
    
    Fixes golang/go#27534.

    • PR libstdc++/87749 fix (and optimize) string move construction · 71e09389 
      The move constructor for the SSO string uses assign(const basic_string&)
when either:

(1) the source string is "local" and so the contents of the small string
buffer need to be copied, or

(2) the allocator does not propagate and is_always_equal is false.

Case (1) is suboptimal, because the assign member is not noexcept and
the compiler isn't smart enough to see it won't actually throw in this
case. This causes extra code in the move assignment operator so that any
exception will be turned into a call to std::terminate. This can be
fixed by copying small strings inline instead of calling assign.

Case (2) is a bug, because the specific instances of the allocators
could be equal even if is_always_equal is false. This can result in an
unnecessary deep copy (and potentially-throwing allocation) when the
storage should be moved. This can be fixed by simply checking if the
allocators are equal.

    • S/390: Merge movdi_larl into movdi_64 · b6f51755 
      Consider the following RTL:

(insn (set (mem/f/c:DI (reg/f:DI 60))
           (const:DI (plus:DI (symbol_ref:DI ("*.LANCHOR0"))
                              (const_int 8)))))

generated by cse2 pass.  It is matched to movdi_64, resulting in
the following inefficient code:

	larl	%r5,.L6			# Load literal pool@
	lg	%r1,.L7-.L6(%r5)	# Load .LANCHOR0+8
	stgrl	%r1,.LANCHOR0
	br	%r14

Matching it to movdi_larl improves the code, eliminating one
instruction and the literal pool entry:

	larl	%r1,.LANCHOR0+8
	stgrl	%r1,.LANCHOR0
	br	%r14

Taking it one step further, there is no reason to keep movdi_64 and
movdi_larl separate, since this could potentially improve code in other
ways by giving lra one more alternative to choose from.

replaced by the format string check.  However, unlike the old one, this
new check cannot be always performed at compile time, in which case a
