[Qemu-devel] [PATCH 11/20] target/arm: Add support for restoring v8M additional state context

2017-09-22 Thread Peter Maydell
For v8M, exceptions from Secure to Non-Secure state will save callee-saved registers to the exception frame as well as the caller-saved registers. Add support for unstacking these registers in exception exit when necessary. Signed-off-by: Peter Maydell --- target/arm/helper.c | 30 ++
