[Mono-dev] Full AOT compilation of generics supported?
Running a two-week old SVN HEAD version of Mono and have been using the full AOT compilation feature as well as the mono_aot_only mode of running the system so that I can execute managed code on the iPhone. I have been successful in doing so and have been instantiating and executing various managed code methods to verify the functionality. Last night I fully AOT compiled an assembly that has a method with some generics code in it. I basically add a few strings to a List collection. When running this method an assert was triggered and looking at the stack trace it seemed to have stopped when it tried to compile a runtime_invoke_void_* method (not sure about the exact name of this method)... which was created as an "extra" method when previously compiling the generic code. Now, the assert was triggered because I was running with mono_aot_only = TRUE but the code was trying to invoke a JIT compilation. Does this mean that generics isn't supported right now for full AOT compilation? or does it mean that I haven't initialized the system correctly (either at compile time or at runtime)? If it is not supported are there any goals for when this would be available?

Re: [Mono-dev] Full AOT compilation of generics supported?
Hi, full aot + generics is mostly supported, but it is very hard to statically determine the set of generics methods which need to be AOTed so it might not work in all cases. Try current SVN HEAD as there were fixes in this area in the past two weeks.

Re: [Mono-dev] Full AOT compilation of generics supported?
Thanks, I will update my local repository and try again. Is there a specific method that I can put a breakpoint in to see if Mono decides to AOT compile the generic method or not? ...just would like to verify the behavior...

Re: [Mono-dev] Full AOT compilation of generics supported?
Hi again,
I got the latest from SVN and recompiled all of my base libraries again
(mscorlib,System and System.Core) as well as my custom assembly. The base
libraries are taken from the mono/2.1 folder so I am compiling with the
Silverlight binaries.
When I try to run my method I get the following assert...
** ERROR **: Attempting to JIT compile method '(wrapper static-rgctx-invoke)
System.Collections.Generic.Comparer`1:static_rgctx_invoke_void ()'
while running with --aot-only.
This is the code that I am trying to run...
using System;
using System.Collections.Generic;
namespace MonoSLLibrary
{
public class Class1
{
///
/// Cretes a generic list, creates a few items descending order, sorts
the list
/// and returns the first item. The first item should be a "1";
///
///
public string SortListAndReturnFirstItem()
{
List strings = new List();
strings.Add("3");
strings.Add("2");
strings.Add("1");
strings.Sort();
return strings[0];
}
}
}
I guess it is the call to strings.Sort that is causing some issues with the
comparer. Is still one of those rare cases where Mono doesn't JIT-compile or
should this not be happening?

Update on this one..
If I comment out the line that has strings.Sort(); on it I am successful in
retrieving back the string "3" from the managed world.
