[Mesa-dev] [PATCH 0/4] Don't abuse the hash table that much

[Thomas Helland]

We have quite a few places where we are doing hashing multiple times.
These are some cases I found, but there are likely more.

Thomas Helland (4):
  glsl: Hash only once if inserting new elemnt in refcount hash table
  nir: Prehash in instr_set to avoid unnecessary hashing
  util: Implement a hash table cloning function
  glsl: Use hash table cloning in copy propagation
