Subject [drlvm][jit] Code review of the following issue - [jira] Commented: (HARMONY-3246) [drlvm][jit][opt] Jitted code can not be executed on non-SSE2 platforms
Date Wed, 18 Apr 2007 05:52:57 GMT
Would anyone else like to review this patch? It's somewhat
significant. I've tested it on a P4/WinXP and DRLVM works without any
noticeable regressions. I've done some initial tests on a Quad
P3/Ubuntu and I can now run a simple Hello World with the default JIT,
which is a huge step.

If no one has any issues, I'm going to commit this patch.

Nathan Beyer commented on HARMONY-3246:
---------------------------------------

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.
