Subject: [PATCH v2 2/9] gdb: Refactor 'stack.c:print_frame'.
Date: Fri, 23 Jan 2026 08:05:24 +0000 [thread overview]
Message-ID: <20260123080532.878738-3-christina.schimpe@intel.com> (raw)
In-Reply-To: <20260123080532.878738-1-christina.schimpe@intel.com>
[-- Attachment #1: Type: text/plain, Size: 3996 bytes --]
Refactor the function 'stack.c:print_frame' by introducing several
small functions.
The functions will also be used in a later patch "gdb: Implement
'bt shadow' to print the shadow stack backtrace."
