    • Simplify movmem code by always doing overlapping copies when larger than 8 bytes on AArch64. · 89c52e5e 
      This changes the movmem code in AArch64 that does copy for data between 4 and 7
bytes to use the smallest possible mode capable of copying the remaining bytes in one
go and then overlapping the reads if needed.

This means that if we're copying 5 bytes we would issue an SImode and QImode
load instead of two SImode loads.

This does smaller memory accesses but also gives the mid-end a chance to realise
that it can CSE the loads in certain circumstances. e.g. when you have something
like

return foo;

where foo is a struct. This would be transformed by the mid-end into SSA form as

D.XXXX = foo;

return D.XXXX;

This movmem routine will handle the first copy, but it's usually not needed,
the mid-end would do SImode and QImode stores into X0 for the 5 bytes example
but without the first copies being in the same mode, it doesn't know it doesn't
need the stores at all.

    • P0646R1 Improving the Return Value of Erase-Like Algorithms I · ef45724a 
      In C++2a the remove, remove_if and unique members of std::list and
std::forward_list have been changed to return the number of elements
removed. This is an ABI change for the remove members and the
non-template unique members, so an abi-tag is used to give those symbols
new mangled names in C++2a mode. For the function templates the return
type is part of the mangled name so no abi-tag is needed.
