--- Comment #7 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- Author: krebbel Date: Fri Mar 24 13:52:30 2017 New Revision: 246443 URL: https://gcc.gnu.org/viewcvs?rev=246443&root=gcc&view=rev Log: S/390: PR79904: Disallow reg + sym_ref literal pool addresses. We accept reg + sym_ref as valid address if sym_ref is a literal pool reference knowing that it will be rewritten as r13 + reg + offset. However, annotate_constant_pool_refs was never able to handle that. With the patch only single sym_refs are accepted. Regression tested on s390x. 2017-03-24 Andreas Krebbel <kreb...@linux.vnet.ibm.com> PR target/79904 * config/s390/s390.c (s390_decompose_address): Reject reg + sym_ref literal pool references. gcc/testsuite/ChangeLog: 2017-03-24 Andreas Krebbel <kreb...@linux.vnet.ibm.com> * gcc.dg/ubsan/pr79904-2.c: New test.
