LGTM, it's always good to improve some debug for vsetvli insertion pass, it's really non-trivial optimization. On Thu, Jan 25, 2024 at 4:59 PM Juzhe-Zhong wrote: > > While looking into PR113469, I notice the LCM delete a vsetvl incorrectly. > > This patch add dump information of all predecessors

[PATCH] RISC-V: Add LCM delete block predecessors dump information

While looking into PR113469, I notice the LCM delete a vsetvl incorrectly. This patch add dump information of all predecessors for LCM delete vsetvl block for better debugging. Tested no regression. gcc/ChangeLog: * config/riscv/riscv-vsetvl.cc (get_all_predecessors): New function.
