2024-02-06target/s390x: Emulate CVB, CVBY and CVBGIlya Leoshkevich
Convert to Binary - counterparts of the already implemented Convert to Decimal (CVD*) instructions. Example from the Principles of Operation: 25594C becomes 63FA.

2024-02-06target/s390x: Emulate CVDGIlya Leoshkevich
CVDG is the same as CVD, except that it converts 64 bits into 128, rather than 32 into 64. Create a new helper, which uses Int128 wrappers.

2024-02-05target/ppc/cpu-models: Rename power5+ and power7+ for new QOM naming rulesThomas Huth
The character "+" is now forbidden in QOM device names (see commit b447378e1217 - "Limit type names to alphanumerical and some few special characters"). For the "power5+" and "power7+" CPU names, there is currently a hack in type_name_is_valid() to still allow them for compatibility reasons. However, there is a much nicer solution for this: Simply use aliases! This way we can still support the old names without the need for the ugly hack in type_name_is_valid().

2024-02-03target/s390x: Improve general case of disas_jccRichard Henderson
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 Henderson
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_*.
