As noted in another thread, LLVM 15's assembler is now required, before

do.) Hence, the added link to the install documentation.

We can end up creating ADDR_EXPRs of non-addressable entities during

analysis when that would create such invalid ADDR_EXPR as part of
analyzing the ref structure.

We found that when only 128-bit vectorization was enabled, 549.fotonik3d_r
failed to vectorize effectively. For this reason, we adjust the cost of
128-bit vector_stmt that match the multiply-add pattern to facilitate 128-bit
vectorization.
The experimental results show that after the modification,

Hi,
init_all_optabs initializes > 1 patterns for riscv targets. This
leads to pathological situations in dataflow analysis (which can occur
with many adjacent stores).
To alleviate this this patch makes genopinit split the init_all_optabs
function into several init_optabs_xx functions that ea

I haven't looked at the patch, but it sounds you give the result
the wrong type. Then patching up all use cases instead of the
type seems wrong.
