I started looking at implementing full local cache in complement to global
evicting 'struct alg_hash_entry x_alg_hash[NUM_ALG_HASH_ENTRIES];' cache.

I tend to think there may be an issue with costs. There is no pattern
for muldi3 on 32-bit hppa, so we use the generic code from libgcc. How
do we know the cost for this routine?

For the above case, there are during the recursion 77608 synth_mult calls,
which might be ok, so indeed better hashing would help, but 10311 is too large
and is not a prime number. Plus this hash table is re

Can be reproduced on x86_64-linux on the same testcase, just put a breakpoint
on
synth_mult and
(gdb) set var t = -8796714831421723037
(gdb) set cost_limit->cost = 128

Does this help the compile time for xxhash?

synth_mult() is called 57M times on this tiny sample.
I noticed there is a NUM_ALG_HASH_ENTRIES bucket size for already computed
algorithms for multiplication. The below tweak seems to workaround pathol
