Technical tradeoffs
- • Reduced relocations can lead to smaller object files and faster linking, but requires accurate tracking of instruction states.
- • The logic for identifying 'relaxed' instructions needs to be comprehensive and correct for the optimization to be safe.

[PATCH v0 3/4] LoongArch: Emit fewer relocations for label subtraction
This patch for the LoongArch binutils component optimizes relocation emission for label subtraction. It introduces flags to mark fragments and sections with relaxed instructions, preventing the generation of relocations when addsy and subsy occur within the same fragment and no relaxed instructions are interspersed.
