...imits into LLVM itself, rather than try to have people control it this way :) I completely agree! Would be cool to create a suite of extreme inputs, maybe a special llvm test-suite module. This module would contain scripts that produce extreme inputs (long basic blocks, deeply nested loops, utils/create_ladder_graph.py, etc.) In fact I have a python script here as well that generates a few variations of stuff that was interesting to scheduling algos. It would just take someone to setup a proper test-suite and a bot for it and I'd happily contribute more tests :) - Matthias -------------- next part -------...

How do you disable optimization for a function? I ask because my application often compiles machine-generated code that results in pathological structures that take a long time to optimize, for little benefit. As an example, if a basic block has over a million instructions in it, then DSE can take a while, as it is O(n^2) in the number of instructions in the block. In my application (at least),
