* enable cleanup_dead_axes
* don't mess with user contig
* correct tag behavior
* double reshape isn't correct
* block on assign too
* skip messing with symbolic
* Fix tests
* disable RANGEIFY=2
* test w rangeify
* enable RANGEIFY=1 test_assign
* work
* rangeify=0 asserts this ast
* remove that
* beta test, it's correct though
* skip multi
* matches torch/np output
* memcopy without memcopy
* can remove this
* rangeify isn't silently wrong anymore
* diff cleanup
* use UOp toposort instead of global tags
* actual assert TestRangeifyAssign
* step
* work
* this isn't optimizing away now
* some todos
* test fusion schedule
* typo
* dedup idxs
* cleaner
* pre
* work
* diff
* rangeify: fix copy size mismatch errs
* const folding can happen in sym
assert it
* shippable
* rangeify copy is completely wrong
* pre_bufferize
* tag bufferize
* pre back
* use tags instead of graph_rewrite_map in rangeify
* new style, add realize
* metadata works
* simple failure
* fix
* loops
* stuff becomes a NOOP when you remove it
* stuff becomes a NOOP when you remove it
* tags on bufferize
* bmnist works
* locals don't work
* shippable
* fix some tests
* simpler map_realize
* remove const hack
* debuggable test
* broke
* assign test
* straight up bug
* wooo it passes
* sink shouldn't be there
* fix ops
* bmnist
* kv cache ish
* Set RANGEIFY context variable to 0
* should work normal
* better
* types
* hacks to fix test_symbolic
* pm_add_buffers
* tests should pass
* viz: non blocking UOp tracing
* u.arg
* no if Ops.KENREL
* drop replace
* switch to weakref.WeakKeyDictionary
* back
* remove ram usage skips, viz works here
* cache on reconstruct
* non recursive top_down_rewrite
* nicer algorithm
* rewrite bottom up also
* only top down is broken?
* simpler iterative algo
* no recursion errors
* top down and bottom up
* unified rewrite
* simpler rewrite
* clean up comments
* move that comment
* move high level stuff to unit tests [pr]
* process replay on unit tests
* fix pr, less compute
* set omp num threads
* set 200MB buffer size limit
* delete junk
* fix tests
* faster
* move test_indexing to unit
* faster
* remove del spam from CI
* more
* preconstruct default buffer spec
* ignore those errors
* check exception
* more exception check
* skip stuff
* smaller tests mean faster tests
* a few more
