New issue 1840 by [email protected]: High num of deopts for attached
production code from game engine
http://code.google.com/p/v8/issues/detail?id=1840
Please see both the JavaScript and Flash versions of this code which
decompressed PVR textures.
http://www.mandreel.com/demos/test1/index.html
http://www.mandreel.com/demos/test1/indexFlash.html
Notice how the JavaScript version is much slower than the Flash version.
Both of those samples are automatically generated from the same C source
code.
The specific JavaScript code is found in
http://www.mandreel.com/demos/test1/mandreel.js
The specific troublespot is _ZN15chanka_test_pvr15PVRTCDecompressEPKviiiPh
We are seeking advice from the V8 engineers to reduce deopts inside that
function. Anything we can do differently?
Thanks very much in advance!
