S/390: Fix failing RTL check in s390_canonicalize_comparison
The new sigfpe-eh.c fails with
internal compiler error: RTL check: expected elt 0 type 'e' or 'u', have 'w' (rtx const_int)
This is most likely due to a typo: XEXP (*op1, 0) was used, when
XEXP (*op0, 1) was intended. This did not cause any user-visible
problems, because reversed_comparison_code_parts ignores the
respective argument, and the release compiler is built without RTL
checks.
gcc/ChangeLog:
2019-11-06 Ilya Leoshkevich <iii@linux.ibm.com>
* config/s390/s390.c (s390_canonicalize_comparison): Use XEXP
(*op0, 1) instead of XEXP (*op1, 0).
gcc/testsuite/ChangeLog:
2019-11-06 Ilya Leoshkevich <iii@linux.ibm.com>
