The Sea of Nodes and the HotSpot JIT

Cliff will cover the "Sea of Nodes" used by the HotSpot C2 JIT to generate code — probably 99% of "executed" Java bytecodes on the planet run on C2 generated code, and the C2 compiler probably executes (much) more than a trillion times a day.

This talk is targeted for audiences who are already well educated about compilers, and want to become more familiar with the HotSpot "C2" JIT. In particular, it is assumed the audience is familiar with SSA form, basics of graph theory, the bytecode execution model, Java code-loading and unloading, and rudiments of code generation.
