ones noted, which require funny PPC specific inline assembly.
If some angel felt the desire to help me, I think this is that last bit missing
for JIT support (however, generic code emitter might night work right with
the constant pool yet).

for external functions work. CompilationCallback has not been written, and
stubs for internal functions are not generated yet. This means you can call
printf and exit, and use global variables, but cannot call functions local to
a module yet.

reg-reg copies. The necessary conditions for this bug are a GEP that is
used outside the basic block in which it is defined, whose components
other than the pointer are all constant zero, and where the use is
selected before the definition (backwards branch to successsor block).

shouldn't be forced to coalesce for us: folded GEP operations. This too
fires thousands of times across the testsuite.

directly rather than making a copy for the register allocator to coalesce.
This kills thousands of live intervals across the testsuite.

regression vs. the CBE, MultiSource/Applications/hbd.

int test(int x) { return 32768 - x; }
Fixed by teaching the function that checks a constant's validity to be used
as an immediate argument about subtract-from instructions.

for bitfield extract, although it is turned off until fully debugged.

* Convert register numbers from their opcode value to the real value, e.g.
PPC::R1 => 1 and PPC::F1 => 1
* Add correct handling of loading of global values which are PC-relative --
implement ha16() and lo16()

correct asm syntax) so that it's assembled correctly from its constituents

The decimal value given in the manual (8 or 9) really needs to be multiplied by
a factor of 32 because of the group of 5 zero bits after the register code.

emit unnecessary clear operations for code such as:
int foo(int x) { return 1 << x; }
