From: Luis Machado Date: Fri, 21 Feb 2020 20:58:48 +0000 (-0300) Subject: Harden gdb.arch/aarch64-pauth.exp and fix a failure X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=85d2d5bbee1c21c2e3e929cc68fe06d762b3073b;p=binutils-gdb.git Harden gdb.arch/aarch64-pauth.exp and fix a failure When running this testcase against a QEMU with PAC support, i noticed we were failing to recognize the additional [PAC] that is emitted in the backtrace, resulting in this failure: FAIL: gdb.arch/aarch64-pauth.exp: backtrace I've made the test use multi_line to make the pattern more clear.
