--- Comment #2 from JuzheZhong <juzhe.zhong at rivai dot ai> --- I have thought about this long time ago while I am working on supporting RVV on upstream GCC. https://github.com/riscv-non-isa/riscv-toolchain-conventions/issues/37 I suggested we should have -mprefer-agnostic in RISC-V psabi. When this option is allowed, the problem can be solved very easily: /* Get prefer tail policy. */ enum tail_policy get_prefer_tail_policy () { /* TODO: By default, we choose to use TAIL_ANY which allows compiler pick up either agnostic or undisturbed. Maybe we will have a compile option like -mprefer=agnostic to set this value???. */ return TAIL_ANY; } /* Get prefer mask policy. */ enum mask_policy get_prefer_mask_policy () { /* TODO: By default, we choose to use MASK_ANY which allows compiler pick up either agnostic or undisturbed. Maybe we will have a compile option like -mprefer=agnostic to set this value???. */ return MASK_ANY; } in riscv-v.cc. I have already leave a TODO here.
