On aarch64-linux, I run into: ... FAIL: gdb.base/annota1.exp: backtrace from shlibrary (timeout) ... due to the PAC marker showing up: ... ^Z^Zframe-address^M 0x000000000041025c [PAC]^M ^Z^Zframe-address-end^M ... In the docs the marker is documented as follows: ... When GDB is debugging the AArch64 architecture, and the program is using the v8.3-A feature Pointer Authentication (PAC), then whenever the link register $lr is pointing to an PAC function its value will be masked. When GDB prints a backtrace, any addresses that required unmasking will be postfixed with the marker [PAC]. When using the MI, this is printed as part of the addr_flags field. ... Update the test-case to allow the PAC marker. Likewise in a few other test-cases. While we're at it, rewrite the affected pattern pat_begin in annota1.exp into a more readable form. Likewise for the corresponding pat_end. Tested on aarch64-linux. Approved-By: Luis Machado <luis.machado@arm.com> PR testsuite/31202 Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31202
