2023-01-17tcg: Remove TCG_TARGET_HAS_direct_jumpRichard Henderson
We now have the option to generate direct or indirect goto_tb depending on the dynamic displacement, thus the define is no longer necessary or completely accurate. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2023-01-06tcg/s390x: Remove DISTINCT_OPERANDS facility checkRichard Henderson
The distinct-operands facility is bundled into facility 45, along with load-on-condition. We are checking this at startup. Remove the a0 == a1 checks for 64-bit sub, and, or, xor, as there is no space savings for avoiding the distinct-operands insn.

2023-01-06tcg/s390x: Check for load-on-condition facility at startupRichard Henderson
The general-instruction-extension facility was introduced in z196, which itself was end-of-life in 2021. In addition, z196 is the minimum CPU supported by our set of supported operating systems: RHEL 7 (z196), SLES 12 (z196) and Ubuntu 16.04 (zEC12). Check for facility number 45, which will be the consilidated check for several facilities.

2023-01-05tcg: Replace TCG_TARGET_EXTEND_ARGS with TCG_TARGET_CALL_ARG_I32Richard Henderson
For 64-bit hosts that had TCG_TARGET_EXTEND_ARGS, set TCG_TARGET_CALL_ARG_I32 to TCG_CALL_ARG_EXTEND. Otherwise, use TCG_CALL_ARG_NORMAL. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-01-05tcg: Replace TCG_TARGET_CALL_ALIGN_ARGS with TCG_TARGET_CALL_ARG_I64Richard Henderson
For 32-bit hosts when TCG_TARGET_CALL_ALIGN_ARGS was set, use TCG_CALL_ARG_EVEN. For 64-bit hosts, TCG_TARGET_CALL_ALIGN_ARGS was silently ignored, so always use TCG_CALL_ARG_NORMAL.
