2013-01-05target-s390: Convert IPMRichard Henderson
Note that the previous placement of the PM field was incorrect. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Convert FP ADD, COMPARE, LOAD TEST/ROUND/LENGTHENEDRichard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Convert SHIFT, ROTATE SINGLERichard Henderson
Note that we were missing the 32-bit SLA. 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>
2012-09-10target-s390x: avoid AREG0 for condition code helpersBlue Swirl
Make condition code helpers take a parameter for CPUState instead of relying on global env. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-09-10target-s390x: avoid AREG0 for FPU helpersBlue Swirl
Make FPU helpers take a parameter for CPUState instead of relying on global env. Introduce temporary wrappers for FPU load and store ops. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Alexander Graf <agraf@suse.de>
