PowerPC was the one outlier that defined both ELF_ARCH and
ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating
the definition of elf_check_arch.
However, the elf file header field in question is called
e_machine, so ELF_MACHINE is in fact the better name.
Mechanically change most target/target_elf.h files,
then adjust ppc/target_elf.h manually.
Do not provide a default for ELF_MACHINE.

Rename from cpu_get_model to emphasize that this is an elf-specific
function. Declare the function once in loader.h.

This struct is unused since Peter's

However, hmm, I'm a bit confused since that commit modifies the

Step in removing CC_OP: change the representation of CC_OP_FLAGS.
The 8 bits are distributed between 6 variables, which should make
it easy to keep up to date.
The code within cc_helper.c is quite ugly but is only temporary.

For the most part priviledged opcodes are ifdefed out of the
user-only sparc translator, which will then incorrectly produce
illegal opcode traps. But there are some code paths that
properly raise TT_PRIV_INSN, so we must handle it.

Use TT_TRAP.
For sparc32, 0x88 is the "Slowaris" system call, currently BAD_TRAP
in the kernel's ttable_32.S. For sparc64, 0x110 is tl0_linux32, the
sparc32 trap, now folded into the TARGET_ABI32 case via TT_TRAP.
For sparc64, there does still exist trap 0x111 as tl0_oldlinux64,
which was replaced by 0x16d as tl0_linux64 in 1998. Since no one
has noticed, don't bother implementing it now.
