    • S/390: Merge compare of compare results · eca98038 
      With this patch EQ and NE compares on CC mode reader patterns are
folded.  This allows using the result of the vec_all_* and vec_any_*
builtins directly in a conditional jump instruction as in the attached
testcase.

	of CC mode values.
	(s390_reverse_condition): New function.
	* config/s390/s390.h (REVERSE_CC_MODE, REVERSE_CONDITION): Define

    • S/390: Fix vector all/any cc modes. · a6a2b532 
      This fixes a problem with the vector compares producing CC mode
results.

The instructions produce condition code modes which can be either
interpreted to check an ALL elements or an ANY element result.  As the
modes where used before they could not be inverted by the middle-end
by inverting the comparison code (e.g. eq to ne).  The result usually
was just wrong.

In fact inverting a comparison code on an CCVALL mode would require to
also change the mode to CCVANY but this cannot be done easily in the
middle-end.  With this patch the meaning of an ALL cc mode only refers
to the not-inverted comparison code (e.g. eq, gt, ge).  With that
change inverting the comparison code matches a not operation on the
condition code mask again.

Bootstrapped and regression tested on s390 and s390x.

Bye,

-Andreas-
