One of the compiler people would have to answer that one.
Not a person who works on either the compiler or the runtime, but a compiler-literate individual who's been following the project for a while. The Portable.NET runtime consumes "CIL" instructions, which as you say above are designed to be Just-In-Time compiled, not directly interpreted. The CVM interpreter in the original run-time design 'compiled' CIL instructions to CVM instructions, then interpreted the latter. The libjit version of the runtime compiles the CIL instructions to either machine code or to a libjit interpreter, which has no connection to the old CVM interpreter. The compiler emits CIL instructions only, and has no awareness of any of this. Hope this helps. _______________________________________________ Developers mailing list [email protected] http://dotgnu.org/mailman/listinfo/developers
