Hello, This version addresses review comments from Eli and Luis. There are only small changes in patches 5, 8 and 9. The individual patches have changelogs pointing out the differences. As with v2, the first 3 patches are from Christina's CET shadow stack v4 series and are included in this series so that the CI can apply and test it. For convenience, I pushed the branch users/bauermann/gcs-v3 to the GDB repo containing the whole stack. v2 can be found here: https://inbox.sourceware.org/gdb-patches/20250618055445.709416-1-thiago.bauermann@linaro.org/ v1 can be found here: https://inbox.sourceware.org/gdb-patches/20250608010338.2234530-1-thiago.bauermann@linaro.org/ Christina Schimpe (3): GDB: Linux: Add function linux_address_in_shadow_stack_mem_range gdb, gdbarch: Enable inferior calls for shadow stack support. gdb, gdbarch: Introduce gdbarch method to get the shadow stack pointer.
