Bug ID: 26611
Summary: Arm: PSP thread stack unwinding 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, exception stack can store the registers in a stack pointed to by
the in a PSP register.
This is currently not supported. We only support using the SP register.
See this comment in arm-tdep.c arm_m_exception_cache()
/* Thread (process) stack used.
Potentially this could be other register defined by target, but PSP
can be considered a standard name for the "Process Stack Pointer".
To be fully aware of system registers like MSP and PSP, these could
be added to a separate XML arm-m-system-profile that is valid for
ARMv6-M and ARMv7-M architectures. Also to be able to debug eg a
corefile off-line, then these registers must be defined by GDB,
and also be included in the corefile regsets. */
