PR 109399
gcc/ChangeLog:
* config/riscv/riscv-vsetvl.cc
(pass_vsetvl::compute_local_backward_infos): Update user vsetvl in local demand
fusion.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/vsetvl/pr109399.c: New test.
Thanks. Installed.
I noted that change_vsetvl_insn does not have a function comment. Can
you please add one. Perhaps something like this:
/* INSN is either a vector configuration insn, or an insn with a vtype
that is immediately preceded by a vector configuration insn. In
both cases, change the vector configuration insn to utilize the
vector configuration state in INFO. */
