2013-12-17	target-arm: Clean up handling of AArch64 PSTATE	Peter Maydell	1	-2/+2
	The env->pstate field is a little odd since it doesn't strictly speaking represent an architectural register. However it's convenient for QEMU to use it to hold the various PSTATE architectural bits in the same format the architecture specifies for SPSR registers (since this is the same format the kernel uses for signal handlers and the KVM register). Add some structure to how we deal with it: * document what env->pstate is * add some #defines for various bits in it * add helpers for reading/writing it taking account of caching of NZCV, and use them where appropriate * reset it on startup Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1385645602-18662-3-git-send-email-peter.maydell@linaro.org Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org>
2013-09-10	target-arm: Add AArch64 gdbstub support	Alexander Graf	1	-0/+73
	We want to be able to debug AArch64 guests. So let's add the respective gdb stub functions and xml descriptions that allow us to do so.
