The reason is that Fedora has cross-compilers, but no cross-glibc headers. Fix by hardcoding the format specifiers and dropping the include. An alternative fix would be to introduce a configure check for inttypes.h. But this would make it impossible to use Fedora cross-compilers for softmmu tests, which used to work so far.

The previous format has a problem in that it is difficult to recreate a valid sign mask after a shift operation: the "repetitions" part of the previous format meant that applying the same shift as for the value lead to an off-by-one value. The new format, including the sign bit itself, means that the sign mask can be manipulated in exactly the same way as the value, canonicalization is easier. Canonicalize the s_mask in fold_masks_zs, rather than requiring callers to do so. Treat 0 as a non-canonical but typeless input for no sign information, which will be reset as appropriate for the data type. We can easily fold in the data from z_mask while canonicalizing. Temporarily disable optimizations using s_mask while each operation is converted to use fold_masks_zs and to the new form.

<zhiwei_liu@linux.alibaba.com> For riscv host, it will set dec->cfg to zero. Thus we shuld guard the dec->cfg deference for riscv host disassemble. And in general, we should only use dec->cfg for target in three cases: 1) For not incompatible encodings, such as zcmp/zcmt/zfinx. 2) For maybe-ops encodings, they are better to be disassembled to the "real" extensions, such as zicfiss. The guard of dec->zimop and dec->zcmop is for comment and avoid check for every extension that encoded in maybe-ops area. 3) For custom encodings, we have to use dec->cfg to disassemble custom encodings using the same encoding area.

Therefore, when they generate exceptions, they are not handled by cpu_restore_state_from_tb(). For x86 this is not a problem, because x86_restore_state_to_opc() only restores pc and cc, which already have the correct values if the first TB instruction causes an exception. However, on several other architectures, restore_state_to_opc() is not stricly limited to state restoration and affects some exception-related registers, where guests can notice incorrect values, for example: - arm's exception.syndrome; - hppa's unwind_breg; - riscv's excp_uw2; - s390x's int_pgm_ilen. Fix by always calling tcg_tb_insert(). This may increase the size of region_trees, but tcg_region_reset_all() clears it once code_gen_buffer fills up, so it will not grow uncontrollably. Do not call tb_link_page(), which would add such TBs to the QHT, to prevent tb_lookup() from finding them. These TBs are single-use, since subsequent reads from I/O memory may return different values; they are not removed from code_gen_buffer only in order to keep things simple.
