Peter Maydell 709a340d67 tcg/sparc: Zero extend data argument to store helpers ... The C store helper functions take the data argument as a uint8_t, uint16_t, etc depending on the store size. The SPARC calling convention requires that data types smaller than the register size must be extended by the caller. We weren't doing this, which meant that if QEMU was compiled with optimizations enabled we could end up storing incorrect values to guest memory. (In particular the i386 guest BIOS would crash on startup.) Add code to the trampolines that call the store helpers to do the zero extension as required.
