Comment 2 Kevin Buettner 2023-08-24 01:00:32 UTC

I doubt that Fedora GDB contains support for the Xilinx microblaze, but even if it does, the bug in question was fixed by Alan Modra in late 2019. I've verified that the source code from which GDB is built already contains the fix in question.

Closing this bug...
