2024-02-03target/s390x: Improve general case of disas_jccRichard Henderson1-44/+22
Avoid code duplication by handling 7 of the 14 cases by inverting the test for the other 7 cases. Use TCG_COND_TSTNE for cc in {1,3}. Use (cc - 1) <= 1 for cc in {1,2}.

2024-02-03target/sparc: Merge check_ieee_exceptions with FPop helpersRichard Henderson3-129/+219
If an exception is to be raised, the destination fp register should be unmodified. The current implementation is incorrect, in that double results will be written back before calling gen_helper_check_ieee_exceptions, despite the placement of gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[]. We can simplify the entire implementation by having each FPOp helper call check_ieee_exceptions. For the moment this requires that all FPop helpers write to the TCG global cpu_fsr, so remove TCG_CALL_NO_WG from the DEF_HELPER_FLAGS_*.
