2024-07-18target/arm: Fix handling of LDAPR/STLR with negative offsetPeter Maydell
When we converted the LDAPR/STLR instructions to decodetree we accidentally introduced a regression where the offset is negative. The 9-bit immediate field is signed, and the old hand decoder correctly used sextract32() to get it out of the insn word, but the ldapr_stlr_i pattern in the decode file used "imm:9" instead of "imm:s9", so it treated the field as unsigned. Fix the pattern to treat the field as a signed immediate.

2024-05-30target/arm: Implement FEAT WFxT and enable for '-cpu max'Peter Maydell
FEAT_WFxT introduces new instructions WFIT and WFET, which are like the existing WFI and WFE but allow the guest to pass a timeout value in a register. The instructions will wait for an interrupt/event as usual, but will also stop waiting when the value of CNTVCT_EL0 is greater than or equal to the specified timeout value. We implement WFIT by setting up a timer to expire at the right point; when the timer expires it sets the EXITTB interrupt, which will cause the CPU to leave the halted state. If we come out of halt for some other reason, we unset the pending timer. We implement WFET as a nop, which is architecturally permitted and matches the way we currently make WFE a nop.
