OK, fine -- an example of MCJIT that sets up for PTX JIT would also be helpful.

Is there a succinct way I can get the full list of which optimization passes are applied, and in what order, for standard clang -O1, -O2, -O3? -- Larry Gritz lg at larrygritz.com

...JITing, can I still call the JITed code? If not, may I suggest as a future feature either the ability for the client app to take complete ownership of the JIT code, or else to ask the Module/EE to release as many resources and memory as possible except the callable JIT code? -- Larry Gritz lg at larrygritz.com
