2013-01-05target-s390: Convert LRARichard Henderson1-1/+1
Note that truncating the store to r1 based on PSW_MASK_64 is incorrect. We always modify the entire register. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Convert INSERT CHARACTERS UNDER MASKRichard Henderson1-1/+0
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: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROWRichard Henderson1-3/+0
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 Henderson1-1/+1
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: Register helpersRichard Henderson1-17/+4
Which highlights a lot of cc helpers that no longer exist. Signed-off-by: Richard Henderson <rth@twiddle.net>

2012-10-28target-s390x: rename helper flagsAurelien Jarno1-38/+38
Rename helper flags to the new ones. This is purely a mechanical change, it's possible to use better flags by looking at the helpers. Cc: Alexander Graf <agraf@suse.de> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-09-10target-s390x: switch to AREG0 free modeBlue Swirl1-39/+39
Add an explicit CPUState parameter instead of relying on AREG0. Remove temporary wrappers and switch to AREG0 free mode. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> [agraf: fix conflicts] Signed-off-by: Alexander Graf <agraf@suse.de>
2012-09-10target-s390x: avoid AREG0 for misc helpersBlue Swirl1-13/+13
Make misc helpers take a parameter for CPUState instead of relying on global env. Signed-off-by: Blue Swirl <blauwirbel@gmail.com> [agraf: fix conflict] Signed-off-by: Alexander Graf <agraf@suse.de>

2012-09-10target-s390x: avoid AREG0 for FPU helpersBlue Swirl1-63/+63
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>
