2020-01-27	target/hppa: Allow, but diagnose, LDCW aligned only mod 4	Richard Henderson
	The PA-RISC 1.1 specification says that LDCW must be aligned mod 16 or the operation is undefined. However, real hardware only generates an unaligned access trap for unaligned mod 4. Match real hardware, but diagnose with GUEST_ERROR a violation of the specification. At the same time fix a bug in the initialization of mop, where the size was specified twice, and another to free the zero temporary.

2018-01-31	target/hppa: Implement halt and reset instructions	Helge Deller
	Real hardware would use an external device to control the power. But for the moment let's invent instructions in reserved space, to be used by our custom firmware. Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2018-01-30	target/hppa: Split address size from register size	Richard Henderson
	For system mode, we will need 64-bit virtual addresses even when we have 32-bit register sizes. Since the rest of QEMU equates TARGET_LONG_BITS with the address size, redefine everything related to register size in terms of a new TARGET_REGISTER_BITS.

2017-01-23	target-hppa: Add framework and enable compilation	Richard Henderson
	This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.
