Subject [jira] Commented: (HARMONY-3246) [drlvm][jit][opt] Jitted code can not be executed on non-SSE2 platforms
Date Fri, 20 Apr 2007 07:58:16 GMT

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.

older than Pentium 4.
