* trace: [tcg] Include TCG-tracing header on all targetsLluís Vilanova2014-08-121-0/+2

* target-s390x: Remove unused ld_code6() functionPeter Maydell2014-06-241-5/+0Star
| | | | | | | | The ld_code6() function is unused; remove it. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
* softmmu: introduce cpu_ldst.hPaolo Bonzini2014-06-051-0/+1
| | | | | | | | | | This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch.

* tcg: Invert the inclusion of helper.hRichard Henderson2014-05-281-3/+2Star
| | | | | | | | | | 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>
* cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber2014-03-131-2/+2
| | | | | | | | Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>

| | | | | | | | | | The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount.

* target-s390: Perform COMPARE AND SWAP inlineRichard Henderson2013-01-051-34/+118
| | | | | | | Still no proper solution for CONFIG_USER_ONLY, but the system version is significantly better. Signed-off-by: Richard Henderson <rth@twiddle.net>
* target-s390: Optimize get_addressRichard Henderson2013-01-051-26/+18Star
| | | | | | | | | 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>
* target-s390: Optimize ADDC/SUBBRichard Henderson2013-01-051-19/+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.

* target-s390: Optimize ADDU/SUBU CC testingRichard Henderson2013-01-051-0/+68
| | | | | | We can easily generate some masks for logical add/subtract inline. Signed-off-by: Richard Henderson <rth@twiddle.net>
* target-s390: Tidy comparisonsRichard Henderson2013-01-051-22/+17Star
| | | | | | | | | | | 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>
* target-s390: Optmize emitting discardsRichard Henderson2013-01-051-6/+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>

| | | | | | | | | | | | 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. Signed-off-by: Richard Henderson <rth@twiddle.net>
