--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andreas Krebbel <kreb...@gcc.gnu.org>: https://gcc.gnu.org/g:220ffae474db36ba20487427be699f0987a00b0c commit r11-2662-g220ffae474db36ba20487427be699f0987a00b0c Author: Andreas Krebbel <kreb...@linux.ibm.com> Date: Wed Aug 12 08:02:35 2020 +0200 IBM Z: Fix PR96308 For the testcase a symbol with a TLS reloc and an unary minus is being generated. The backend didn't handle this correctly. In s390_cannot_force_const_mem an unary minus on a symbolic constant is rejected now since gas would not allow this. legitimize_tls_address now makes the NEG rtx the outermost operation by pulling it out of the CONST rtx. gcc/ChangeLog: PR target/96308 * config/s390/s390.c (s390_cannot_force_const_mem): Reject an unary minus for everything not being a numeric constant. (legitimize_tls_address): Move a NEG out of the CONST rtx. gcc/testsuite/ChangeLog: PR target/96308 * g++.dg/pr96308.C: New test.
