    • combine: More make_more_copies · 16ac6fa5 
      This makes make_more_copies do what its documentation says, that is,
only make an intermediate pseudo if copying to a pseudo.

This regressed generated code quality when we didn't keep the original
notes that were on the copy, but since r265582 we do, and only allowing
pseudos now is a win.  It also simplifies the code.


	* combine.c (make_more_copies): Only make an intermediate copy if the
	dest of a move is a pseudo.

    • S/390: Allow relative addressing of literal pool entries · 340e0dd6 
      r265490 allowed the compiler to choose in a more flexible way whether to
use load or load-address-relative-long (LARL) instruction.  When it
chose LARL for literal pool references, the latter ones were rewritten
by pass_s390_early_mach to use UNSPEC_LTREF, which assumes base register
usage, which in turn is not compatible with LARL.  The end result was an
ICE because of unrecognizable insn.

UNSPEC_LTREF and friends are necessary in order to communicate the
dependency on the base register to pass_sched2.  When relative
addressing is used, no base register is necessary, so in such cases the
rewrite must be avoided.
