2015-02-03target-s390: Implement LURA, LURAG, STURGRichard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Use noreturn for exception and load_pswRichard Henderson
Both always exit the cpu loop. Signed-off-by: Richard Henderson <rth@twiddle.net>

Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Use TCG_CALL_NO_WG for integer helpersRichard Henderson
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 Henderson
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 Henderson
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 Henderson
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 Henderson
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 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: 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: Register helpersRichard Henderson
Which highlights a lot of cc helpers that no longer exist. Signed-off-by: Richard Henderson <rth@twiddle.net>
