2020-06-16target/arm: Convert Neon 3-reg-diff prewidening ops to decodetreePeter Maydell3-12/+151
Convert the "pre-widening" insns VADDL, VSUBL, VADDW and VSUBW in the Neon 3-registers-different-lengths group to decodetree. These insns work by widening one or both inputs to double their size, performing an add or subtract at the doubled size and then storing the double-size result. As usual, rather than copying the loop of the original decoder (which needs awkward code to avoid problems when source and destination registers overlap) we just unroll the two passes.

2020-06-15s390x/event-facility: Simplify creation of SCLP event devicesMarkus Armbruster1-35/+29
init_event_facility() creates the SCLP events bus with two SCLP event devices (sclpquiesce and sclp-cpu-hotplug). It leaves the devices unrealized. A comment explains they will be realized "via the bus". The bus's realize method sclp_events_bus_realize() indeed realizes all unrealized devices on this bus. It carries a TODO comment claiming this "has to be done in common code". No other bus realize method realizes its devices. The common code in question is bus_set_realized(), which has a TODO comment asking for recursive realization. It's been asking for years. The only devices sclp_events_bus_realize() will ever realize are the two init_event_facility() puts there. Simplify as follows: * Make the devices members of the event facility instance struct, just like the bus. object_initialize_child() is simpler than object_property_add_child() and object_unref(). * Realize them in the event facility realize method. This is in line with how such things are done elsewhere.

This is the same transformation as in the previous commit, except sysbus_init_child_obj() and realize are too separated for the commit's Coccinelle script to handle, typically because sysbus_init_child_obj() is in a device's instance_init() method, and the matching realize is in its realize() method.

usb_try_create_simple() is qdev_try_new() and qdev_realize_and_unref() with more verbose error messages. Of its two users, one ignores errors, and the other asserts they are impossible.

2020-06-15ssi: ssi_auto_connect_slaves() never does anything, dropMarkus Armbruster7-46/+0
ssi_auto_connect_slaves(parent, cs_line, bus) iterates over @parent's QOM children @dev of type TYPE_SSI_SLAVE. It puts these on @bus, and sets cs_line[] to qdev_get_gpio_in_named(dev, SSI_GPIO_CS, 0). Suspicious: there is no protection against overrunning cs_line[]. Turns out it's safe because ssi_auto_connect_slaves() never finds any such children. Its called by realize methods of some (but not all) devices providing an SSI bus, and gets passed the device. SSI slave devices are always created with ssi_create_slave_no_init(), optionally via ssi_create_slave(). This adds them to their SSI bus. It doesn't set their QOM parent. ssi_create_slave_no_init() is always immediately followed by qdev_init_nofail(), with no QOM parent assigned, so device_set_realized() puts the device into the /machine/unattached/ orphanage. None become QOM children of a device providing an SSI bus. ssi_auto_connect_slaves() was added in commit b4ae3cfa57 "ssi: Add slave autoconnect helper". I can't see which slaves it was supposed to connect back then.
