S/390: Fix PR94666
The vector popcount expanders use a hardcoded subreg. This might lead
to double subregs being generated which then fail to match. With this
patch simplify_gen_subreg is used instead to fold the subregs.
gcc/ChangeLog:
2020-04-20 Andreas Krebbel <krebbel@linux.ibm.com>
* config/s390/vector.md ("popcountv8hi2_vx", "popcountv4si2_vx")
("popcountv2di2_vx"): Use simplify_gen_subreg.
gcc/testsuite/ChangeLog:
2020-04-20 Andreas Krebbel <krebbel@linux.ibm.com>
* g++.dg/pr94666.C: New test.
