2013-07-09target-s390x: Change gen_intermediate_code_internal() argument to S390CPUAndreas Färber
Also use bool type while at it. Prepares for moving singlestep_enabled field to CPUState. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-06-28cpu: Turn cpu_dump_{state,statistics}() into CPUState hooksAndreas Färber
Make cpustats monitor command available unconditionally. Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec() arguments to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-05-01Trivial grammar and spelling fixesStefan Weil
similiar -> similar recieve -> receive transfered -> transferred preperation -> preparation Most changes are in comments, one modifies a parameter name in a function prototype. The spelling fixes were made using codespell. Signed-off-by: Stefan Weil <sw@weilnetz.de> Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

Fix various typos and misspellings. The bulk of these were found with codespell. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell
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. Rename them to gen_tb_start/end.

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: Optimize get_addressRichard Henderson
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 Henderson
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 Henderson
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 Henderson
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 Henderson
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 Henderson
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.
