For floating point vector compares the target mode is an integer mode
which accidently was used as register mode when forcing the compare
operands into regs.
gcc/ChangeLog:
* config/s390/s390.c (s390_expand_vcond): Use the compare operand
mode.
gcc/testsuite/ChangeLog:
* gcc.target/s390/vector/vec-vcond-1.c: New test.

* gcc.target/s390/md/movstr-1.c: Allow also the z13 strings
instruction pattern name to prevent the testcase from failing with
-march=z13.
From-SVN: r233551
A handwritten loop for stpcpy using the new z13 vector instructions
appears to be much faster than the millicoded instruction. However,
the implementation is much longer and therefore will only be enabled
when optimization for speed.

* gcc.target/s390/md/movstr-2.c: New test.
gcc/ChangeLog:
* config/s390/s390-protos.h: Add s390_expand_vec_movstr prototype.

to print it as address properly.
From-SVN: r233549
This patch adds proper support for the -mtune=z13 option by adding a
z13 pipeline description. As started with zEC12 we mostly make use of
the sched reorder hooks to implement a grouping strategy. However,
this time we also keep an eye at the instruction mix provided in the
out of order window to allow the hardware to exploit the different
units.
gcc/ChangeLog:
* config/s390/2827.md: Rename ooo_* insn attributes to zEC12_*.
* config/s390/2964.md: New file.
* config/s390/s390.c (s390_get_sched_attrmask): Use the right set
of insn grouping attributes depending on the CPU level.
(s390_get_unit_mask): New function.
(s390_sched_score): Remove the OOO from the scheduling macros.
Add loop to calculate a score for the instruction mix.
(s390_sched_reorder): Likewise plus improve debug output.
(s390_sched_variable_issue): Rename macros as above. Calculate
the unit distances after actually scheduling an insn. Improve
debug output.
(s390_sched_init): Clear last_scheduled_unit_distance array.
* config/s390/s390.md: Include 2964.md.

As part of the final cleanup of aarch64_internal_mov_immediate a return was
accidentally removed. This causes the 2-instruction case to fallthrough
into the general case even when it found a match. An example immediate is
0xcccccccccccccccd which was using 2 instructions in GCC5 but now requires 4.
Adding the return fixes the regressions.
