Ok. Thanks! Andreas

Commit 229752afe315 ("VEC_COND_EXPR optimizations") has improved code generation: we no longer need "vx x,x,-1", which turned out to be superfluous. Instead, we simply swap 0 and -1 arguments of the preceding "vsel". gcc/testsuite/ChangeLog: 2020-11-23 Ilya Leoshkevich <iii@linux.ibm.com> * gcc.target/s390/zvector/autovec-double-quiet-uneq.c: Expect that "vx" is not emitted. * gcc.target/s390/zvector/autovec-float-quiet-uneq.c: Likewise. --- .../gcc.target/s390/zvector/autovec-double-quiet-uneq.c | 5 ++++- .../gcc.target/s390/zvector/autovec-float-quiet-uneq.c | 5 ++++- 2 files changed, 8 insertions(+), 2 deletions(-)
