[PATCH 0/4] x86: operand types handling in gas
Jan Beulich proposes a four-patch series to refactor how operand types are handled in the x86 assembler (gas). The overarching goal is to reduce the memory footprint of instruction templates and improve cache locality. The patches progressively introduce changes, culminating in moving operand type definitions out of the main instruction template structure, thereby reducing redundancy and memory waste.
