2013-01-05target-s390: Use TCG_CALL_NO_WG for integer helpersRichard Henderson1-4/+4
The division routines do not read or write tcg registers, but can raise fixed-point divide exceptions. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Use TCG_CALL_NO_WG for floating-point helpersRichard Henderson1-39/+39
None of them read or write tcg registers, but most can raise fp exceptions. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Use TCG_CALL_NO_WG for memory helpersRichard Henderson1-15/+15
Those that do not read or write tcg registers, but can raise exceptions via memory faults. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Perform COMPARE AND SWAP inlineRichard Henderson1-3/+0
Still no proper solution for CONFIG_USER_ONLY, but the system version is significantly better. Signed-off-by: Richard Henderson <rth@twiddle.net>

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>
