Implement real ext_i32_i64 and extu_i32_i64 ops. They ensure that a
32-bit value is always converted to a 64-bit value and not propagated
through the register allocator or the optimizer.
Backports commit 4f2331e5b67af8172419eb1c8db510b497b30a7b from qemu
Similar to the same fix for user-mode, except this instance
occurs on the softmmu path. Again, the tlb addend must be
the base register, while the guest address is the index.
Backports commit 80adb8fcad4778376a11d394a9e01516819e2327 from qemu
Thanks to the previous patch, it is now easy for tcg_out_qemu_ld and
tcg_out_qemu_st to use a 32-bit zero extended offset. However, the
guest base register x28 must be the base and addr_reg must be the
index.
Backports commit ffc6372851d8631a9f9fa56ec613b3244dc635b9 from qemu
The new argument lets you pick uxtw or uxtx mode for the offset
register. For now, all callers pass TCG_TYPE_I64 so that uxtx
is generated. The bits for uxtx are removed from I3312_TO_I3310.
Backports commit 6c0f0c0f124718650a8d682ba275044fc02f6fe2 from qemu
The addition of MO_AMASK means that places that used inverted masks
need to be changed to use positive masks, and places that failed to
mask the intended bits need updating.
Backports commit 2b7ec66f025263a5331f37d5ad78a625496fd7bd from qemu
The extra information is not yet used but it is now available.
This requires minor changes through all of the tcg backends.
Backports commit 3972ef6f830d65e9bacbd31257abedc055fd6dc8 from qemu
At the tcg opcode level, not at the tcg-op.h generator level.
This requires minor changes through all of the tcg backends,
but none of the cpu translators.
Backports commit 59227d5d45bb3c31dc2118011691c35b3c00879c from qemu
This is less about improved type checking than enabling a
subsequent change to the representation of labels.
