Commit Message

Michael Collison March 3, 2023, 4:52 a.m. UTC 
  This patch adds foundational support by making two functions that handle 
predication policies visibly globally.

gcc/ChangeLog:

     * config/riscv/riscv-vector-builtins.cc (get_tail_policy_for_pred):
     Remove static declaration to to make externally visible.
     (get_mask_policy_for_pred): Ditto.
     * config/riscv/riscv-vector-builtins.h (get_tail_policy_for_pred):
     New external declaration.
     (get_mask_policy_for_pred): Ditto.
