Re: [PATCH] RISC-V: Describe relax passes with a pass table

Kito Cheng announces that a patch has been pushed, refactoring the RISC-V relax pass mechanism in binutils. The change introduces a pass table to describe each relax pass, which includes a reloc selector and optional hooks. This structure is intended to simplify the addition of new relax passes, such as vendor-specific ones or those for the Zcmt extension, by avoiding repetitive code for each new pass.
