Bug ID: 26613
Summary: Arm: Secure stack not supported
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: tdep
Assignee: unassigned at sourceware dot org
Reporter: alahay01 at gcc dot gnu.org
Target Milestone: ---
On cortex M, the exception stack can use a secure stack.
This is not currently supported.
See this comment in arm-tdep.c arm_m_exception_cache()
/* ARMv8-M Exception and interrupt handling is not considered here.
In the ARMv8-M architecture also EXC_RETURN bit S is controlling if
the Secure or Non-secure stack was used. To separate Secure and
Non-secure stacks, processors that are based on the ARMv8-M
architecture support 4 stack pointers: MSP_S, PSP_S, MSP_NS, PSP_NS.
In addition, a stack limit feature is provided using stack limit
registers (accessible using MSR and MRS instructions) in Privileged
level. */
