Hi, It seems the test fails specifically for that version of gdb (15.0.50.20240403-git) when a gdb.Value object which is an integer of more than 8 bytes is cast to an int. This is the case when we test reading the za quadwords.
To address this we have edited the test such that the int cast is not used for the za quadwords when this specific version of gdb is detected. In this case, the test is performed without int casting (which still passes). To declare this to users, we have added a warning message to be printed in this scenario above the test results in the output file run-gdbstub-sysregs-sme.out. I have sent a new version of the patch series with these changes, as well as the added spdx/copyright lines. Please let us know what you think of this approach!
