Note that for STLR, STLLR, LDAR, LDLAR this fixes an under-decoding in the legacy decoder where we were not checking that the RES1 bits in the Rs and Rt2 fields were set. The new function ldst_iss_sf() is equivalent to the existing disas_ldst_compute_iss_sf(), but it takes the pre-decoded 'ext' field rather than taking an undecoded two-bit opc field and extracting 'ext' from it. Once all the loads and stores have been converted to decodetree disas_ldst_compute_iss_sf() will be unused and can be deleted.

2023-06-19target/arm: Return correct result for LDG when ATA=0Peter Maydell
The LDG instruction loads the tag from a memory address (identified by [Xn + offset]), and then merges that tag into the destination register Xt. We implemented this correctly for the case when allocation tags are enabled, but didn't get it right when ATA=0: instead of merging the tag bits into Xt, we merged them into the memory address [Xn + offset] and then set Xt to that. Merge the tag bits into the old Xt value, as they should be.

2023-06-19target/arm: Fix return value from LDSMIN/LDSMAX 8/16 bit atomicsPeter Maydell
The atomic memory operations are supposed to return the old memory data value in the destination register. This value is not sign-extended, even if the operation is the signed minimum or maximum. (In the pseudocode for the instructions the returned data value is passed to ZeroExtend() to create the value in the register.) We got this wrong because we were doing a 32-to-64 zero extend on the result for 8 and 16 bit data values, rather than the correct amount of zero extension. Fix the bug by using ext8u and ext16u for the MO_8 and MO_16 data sizes rather than ext32u.

2023-06-13target/riscv/vector_helper.c: Remove the check for extra tail elementsXiao Wang
Commit 752614cab8e6 ("target/riscv: rvv: Add tail agnostic for vector load / store instructions") added an extra check for LMUL fragmentation, intended for setting the "rest tail elements" in the last register for a segment load insn. Actually, the max_elements derived in vext_ld*() won't be a fraction of vector register size, since the lmul encoded in desc is emul, which has already been adjusted to 1 for LMUL fragmentation case by vext_get_emul() in trans_rvv.c.inc, for ld_stride(), ld_us(), ld_index() and ldff(). Besides, vext_get_emul() has also taken EEW/SEW into consideration, so no need to call vext_get_total_elems() which would base on the emul to derive another emul, the second emul would be incorrect when esz differs from sew. Thus this patch removes the check for extra tail elements.

2023-06-13target/riscv: Fix initialized value for cur_pmmaskWeiwei Li
We initialize cur_pmmask as -1(UINT32_MAX/UINT64_MAX) and regard it as if pointer mask is disabled in current implementation. However, the addresses for vector load/store will be adjusted to zero in this case and -1(UINT32_MAX/UINT64_MAX) is valid value for pmmask when pointer mask is enabled.
