2013-01-05target-s390: Convert MVCRichard Henderson
The code that was in gen_op_mvc was a bit confused wrt what lengths it wanted to handle. I also disbelieve that the inline memset is worthwhile. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Convert INSERT CHARACTERS UNDER MASKRichard Henderson
Change the CC handling to be more like TEST UNDER MASK, with val & mask. This lets us handle ICMH much more like ICM. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Cleanup cc computation helpersRichard Henderson
The inline markers hid the fact that {n}abs_32 were unused because of typos in the main do_calc_cc function. Let the compiler handle auto-inlining here. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROWRichard Henderson
I'm resonably certain that the carry/borrow-out condition for both helpers was incorrect, failing to take into account the carry-in. Adding the new CC_OP codes also allows removing the awkward interface we used for the slb helpers. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Convert 64-bit MULTIPLY LOGICALRichard Henderson
Use a new "retxl" member of CPUS290XState to return the "eXtra Low" part of a 128-bit value. That said, this will get used when two independent values need returning (e.g. quotient+remainder) as well. At the same time, shuffle the elements of CPUS390XState to get this new space from existing padding in the structure. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Reorg exception handlingRichard Henderson
Make the user path more like the system path. Prepare for more kinds of runtime exceptions. Rename ILC to ILEN to make it clear that we want to pass around a full instruction length, rather than a "code" that happens to be stored one bit left in a larger field. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Split out disas_jccRichard Henderson
Lots of duplicated code replaced with a couple of tables. We no longer attempt to manually invert the logic operation: the comments now match the code. In the fully general test, constant propagate (1 << (3 - cc)) into (8 >> cc). The new function will be usable by non-branch insns as well. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Fix PSW_MASK handlingRichard Henderson
We were treating psw.mask as the 32-bit quantity it is in ESA mode. In particular, the CC field was at the wrong place. Signed-off-by: Richard Henderson <rth@twiddle.net>
