specified register, but a pointer to the in-memory representation of that value. The reason for this is twofold: 1. Not all registers can be represented by a register_t. In particular FP registers fall in that category. Passing the new register value by reference instead of by value makes this point moot. 2. When we receive a G or P packet, both are for writing a register, the packet will have the register value in target-byte order and in the memory representation (modulo the fact that bytes are sent as 2 printable hexadecimal numbers of course). We only need to decode the packet to have a pointer to the register value. This change fixes the bug of extracting the register value of the P packet as a hexadecimal number instead of as a bit array. The quick (and dirty) fix to bswap the register value in gdb_cpu_setreg() as it has been added on i386 and amd64 can therefore be removed and has in fact been that. Tested on: alpha, amd64, i386, ia64, sparc64
