[PATCH for-8.0 v3 29/45] tcg: Define TCG_TYPE_I128 and related helper macros |
Date: |
Fri, 11 Nov 2022 17:40:45 +1000 |
Begin staging in support for TCGv_i128 with Int128.
Define the type enumerator, the typedef, and the
helper-head.h macros.
This cannot yet be used, because you can't allocate
temporaries of this new type.
