[Mono-dev] enabling LLVM / jit with embedded mono

[Jonathan Shore]

I noticed an operation which completes in a fraction of a second when run from the command line with mono is taking many minutes when run as an embedded VM within a C-based app.   It seems almost as if is running without any JIT.

I attempted to provide the --llvm flag when configuring mono within the embedded app, but does not accept.   Did:

	char* options = "--llvm";
	mono_jit_parse_options (1, &options); 

The above fails indicating that does not recognize --llvm.   Looking at the code, -llvm does not appear to be in the argument list.  Ignoring the above setting above, other functions called during initialization are:

	_domain = mono_jit_init (bootassembly);
	_core = mono_domain_assembly_open (_domain, bootassembly);

	// setup config locations
	mono_config_parse (NULL);
		
	...

Is there something else I need to do in order to get JIT and/or LLVM optimisations running?

Thanks
