[Mono-list] RE: [Ikvm-developers] ikvm under mono && mauve tests

[Jeroen Frijters]

Hi Paolo,

Attached is a testcase. Runs in 50ms on MS .NET, takes 16534 ms on Mono
0.l7 (sorry, I don't have a more recent version).

Regards,
Jeroen

[Mono-list] ikvm and Mono 0.20

[Jeroen Frijters]

Title: ikvm and Mono 0.20






Hi,


I tried running ikvm on Mono 0.20 (on Windows) and here are my findings:


* The --noinline and --share-code switches are still required, because otherwise Mono will run the .cctor methods to early (and, by my reading, the Mono behavior is not allowed by the ECMA spec)

* StackFrame.GetFileName() returns "" instead of a null reference when the filename isn't known


* I get an assertion failed: ** ERROR **: file jit.c: line 486 (mono_store_tree): assertion failed: (s->svt != VAL_UNKNOWN) aborting...

* Running mint on ikvm.exe produces no output whatsoever


Regards,

Jeroen
