2013-01-05target-s390: Perform COMPARE AND SWAP inlineRichard Henderson1-34/+118
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: Optimize get_addressRichard Henderson1-26/+18
Don't load the displacement into a register first, add it second so that tcg_gen_addi_i64 can eliminate zeros. Don't mask the displacement first so that we don't turn small negative numbers into large positive numbers. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Optimize ADDC/SUBBRichard Henderson1-19/+37
Giving the proper mask to disas_jcc allows us to generate an inline comparison generating the carry/borrow with setcond. In the very worst case, when we must use the external helper to compute a value for CC, we generate (cc > 1) instead of (cc >> 1), which is only very slightly slower on common cpus. In the very best case, when the CC comes from a COMPARE insn and the compiler is using ALCG with zero, everything folds out to become just the setcond that the compiler wanted.

2013-01-05target-s390: Optimize ADDU/SUBU CC testingRichard Henderson1-0/+68
We can easily generate some masks for logical add/subtract inline. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Tidy comparisonsRichard Henderson1-22/+17
After full conversion, we can audit the uses of LTGT cc ops and see that none of the instructions can ever set CC=3. Thus we can extend the table to treat that bit as ignored. This fixes a regression wrt the pre-conversion translation in which NE was used for both m=6 and m=7. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-01-05target-s390: Optmize emitting discardsRichard Henderson1-6/+24
While they aren't expensive, they aren't free to process. When we know that the three cc helper variables are dead, don't kill them. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-01-05target-s390: Tidy s->op_cc handlingRichard Henderson1-40/+55
There's no need to force computation of the true cc_op when taking an exception or single stepping. In either case we'll enter the next TB with s->cc_op = DYNAMIC and recompute anyway. Just make sure that s->cc_op is stored back to env->cc_op as needed. Delete some dead functions, avoid allocating unused TCG temps, drop the old s->is_jmp setting.

2013-01-05target-s390: Delete dead code from old translatorRichard Henderson1-291/+27
The use of inline restricts detection of static functions that are no longer used. Limit the use of inline to those functions that are conditionally used based on CONFIG_USER_ONLY. Signed-off-by: Richard Henderson <rth@twiddle.net>
