------------------------------------------
Nathan,
AFAIU OPT has only limited support for jvmti, so the error in your log might be expected result actually.
Try running tests with -Drun.all.tests=true to see if there are any other problems.

Nathan Beyer commented on HARMONY-3246:
---------------------------------------
I can test that these changes are passive on P4 platforms, but I can't test these changes on P3 platforms at all since there are lingering 'mfence' assembly instructions being inserted that prevent the VM from starting at all. It would seem that we need to eliminate those changes first before we can do this.

Mikhail Fursov commented on HARMONY-3246:
-----------------------------------------
I have a brief talk with Nikolay (he has no email access now) and he said that x87 is not completely correct because of his patch translates every SSE/SSE2 inst to pentium1 instruction set. So i586 looks the closest possible name and not as misleading as P5.

I thought of "d2x87 " or just "x87" - though "i586" would do as well.

it was actually fixed in update1.diff. Looks likes update2.diff was based on the fix without this variable removed.

I've test this on a Linux P3 and it seems to work. I'm now able to run a simple hello world. Additionally, everything seems to work as it did on a P4/WinXP.
Let's see if we can get a few more people to review the code.

-----------------------------------------
>Would something like "i586" be more appropriate than P3/P5?
I'm OK.
If anyone have other ideas please speak up or I'll redo the patch today.

Mikhail Fursov commented on HARMONY-3246:
-----------------------------------------
BTW, AFAIK this patch allows code to be executed not only on Pentium3 but on Pentium1 also.
What is the best name would be?
P5 looks really confused, P3 is not very precise. Are there any other ideas?

Mikhail Fursov updated HARMONY-3246:
------------------------------------
Attachment: update2.diff
update2.diff - 'p3/p5' renamed to 'i586'
Nathan,
AFAIK jvmti tests work with JET only. With this patch you can't run them on i586 platform.
