well, it doesn't give errors, but warnings because of unsigned longs being
converted to TCGv_i64, which exact definiton I cannot find in the qemu

the value that should be read isn't read. Maybe that'll work when fixing

Perform the atomic update for hardware management of the access flag

A limitation of the implementation so far is that the page table

Always overriding fi->type was incorrect, as we would not properly

We had only been reporting the stage2 page size. This causes
problems if stage1 is using a larger page size (16k, 2M, etc),

The unconditional loop was used both to iterate over levels
and to control parsing of attributes. Use an explicit goto
in both cases.
While this appears less clean for iterating over levels, we

Add a few DISAS_TARGET_* aliases to reduce the number of
calls to gen_eob() and gen_eob_inhibit_irq(). So far,
only update i386_tr_translate_insn for exiting the block
because of single-step or previous inhibit irq.
