| 2023-02-04 | include/qemu/int128: Use Int128 structure for TCI | Richard Henderson | |
| We are about to allow passing Int128 to/from tcg helper functions, but libffi doesn't support __int128_t, so use the structure. In order for atomic128.h to continue working, we must provide a mechanism to frob between real __int128_t and the structure. Provide a new union, Int128Alias, for this. We cannot modify Int128 itself, as any changed alignment would also break libffi.

| Addition of div and rem on 128-bit integers, using the 128/64->128 divu and 64x64->128 mulu in host-utils. These operations will be used within div/rem helpers in the 128-bit riscv target.
