Now that we can pass 7 parameters, do not encode register
operands within simd_data.
Backports commit 08975da9f0bfcfa654628cae71201a351ba5449a from qemu
Most of the existing users would continue around a loop which
would fault the tlb entry in via a normal load/store.
But for AArch64 SVE we have an existing emulation bug wherein we
would mark the first element of a no-fault vector load as faulted
(within the FFR, not via exception) just because we did not have
its address in the TLB. Now we can properly only mark it as faulted
if there really is no valid, readable translation, while still not
raising an exception. (Note that beyond the first element of the
vector, the hardware may report a fault for any reason whatsoever;
with at least one element loaded, forward progress is guaranteed.)
Backports commit 4811e9095c0491bc6f5450e5012c9c4796b9e59d from qemu
There is quite a lot of code required to compute cpu_mem_index,
or even put together the full TCGMemOpIdx. This can easily be
done at translation time.
Backports commit 500d04843ba953dc4560e44f04001efec38c14a6 from qemu
This implements the feature for softmmu, and moves the
main loop out of a macro and into a function.
Backports commit 116347ce20bb7b5cac17bf2b0e6f607530b50862 from qemu
We can choose the endianness at translation time, rather than
re-computing it at execution time.

We can choose the endianness at translation time, rather than

Backports commit 7d0a57a2e1cea188b9023261a404d7a211117230 from qemu
This fixes the endianness problem for softmmu, and moves
the main loop out of a macro and into an inlined function.
Backports commit 78cf1b886aa1b95c97fc5114641515c2892bb240 from qemu
This fixes the endianness problem for softmmu, and moves
the main loop out of a macro and into an inlined function.
Backports commit d4f75f25b43041e7a46d12352b3c70ae457d8cea from qemu
This fixes the endianness problem for softmmu, and moves the
main loop out of a macro and into an inlined function
Backports commit 9fd46c8362e0a45d04ccceae7051d06dd65c1d57 from qemu
Use the same *_tlb primitives as we use for ld1.
For linux-user, this hoists the set of helper_retaddr. For softmmu,
hoists the computation of the current mmu_idx outside the loop,
fixes the endianness problem, and moves the main loop out of a
macro and into an inlined function.
Backports commit f27d4dc2af0de9b7b45c955882b8420905c6efe8 from qemu
Uses tlb_vaddr_to_host for correct operation with softmmu.
Optimize for accesses within a single page or pair of pages.
Backports commit 9123aeb6fcb14e0955ebe4e2a613802cfa0503ea from qemu
The pseudocode for this operation is an increment + compare loop,
so comparing <= the maximum integer produces an all-true predicate.
Rather than bound in both the inline code and the helper, pass the
helper the number of predicate bits to set instead of the number
of predicate elements to set.
Backports commit bbd0968c458d48e34a08b8694fa3309a9fe1c9e7 from qemu
The normal vector element is sign-extended before
comparing with the wide vector element.
Backports commit df4e001093988544d09887122ae824f18ba55c68 from qemu
'I' was being double-incremented; correctly within the inner loop
and incorrectly within the outer loop.
Backports commit 628fc75f3a3bb115de3b445c1a18547c44613cfe from qemu
We already check for the same condition within the normal integer
sdiv and sdiv64 helpers. Use a slightly different formation that
does not require deducing the expression type.
