Add TypedArray polyfill or shim for IE9, IE8 and downlevel Android devices.

[GoogleCodeExporter]

What steps will reproduce the problem?

---
1. Load octane URL  in IE9.0 (current version of IE at time of writing)

http://octane-benchmark.googlecode.com/svn/latest/index.html

2. Click "Start Octane"
3. Nothing happens


What is the expected output? What do you see instead?

---
Expected is suite should run, using commonly used backwards compatibility shims 
used by web developers for their own applications.
What is seen is nothing happens


What version of the product are you using? On what operating system?

---
IE9.0 fully patched on Windows 7 fully patched.


Please provide any additional information below.

---

Developers write apps today using typed arrays targetting IE9, IE8 and 
downlevel Android clients. The apps run JUST FINE. 

Perhaps they are slow, but there is no reliable way to determine this without a 
benchmark which also runs on those platforms.

Adding a polyfill shim for TypedArrays will turn this into a realistic 
benchmark for those scenarios, and will mirror good development practice 
actually in use at this time.

A commonly used shim is here:

Hello,

I cannot reproduce the behavior you describe. Octane runs fine on Win7 (fully 
patched) on IE9.0.8112.16421
Could you give us more information, such as IE version? Could you also open the 
debug console (F12) and see if you get error messages there? Btw, make sure you 
don't have any extensions or plugin and nothing else is running in the 
background.

Regarding the TypedArrays suggestion, we will evaluate. The goal is to measure 
specifically TypedArray performances since there's very little out there that 
does it, so falling back to standard types is not an option.

OK well it seems to have been updated since I filed the bug since the behaviour 
has changed (now reports "Typed Arrays partly or not supported - some tests 
will be skipped"), but still not working for me. Have you got it in your 
"Trusted Sites" list perhaps?


IE Version: 9.0.8112.16421
Update versions: 9.0.9 (KB2722913)


F12 gives this output - I suspect the last line is the killer:

SCRIPT445: Object doesn't support this action 
base.js, line 85 character 1
SCRIPT438: Object doesn't support property or method 'defineProperty' 
deltablue.js, line 49 character 1
SCRIPT1003: Expected ':' 
pdfjs.js, line 493 character 9
SCRIPT5009: 'Float64Array' is undefined 
mandreel.js, line 159 character 1
SCRIPT438: Object doesn't support property or method 'defineProperty' 
box2d.js, line 71 character 453
SCRIPT438: Object doesn't support property or method 'CountBenchmarks' 
index.html, line 65 character 3
LOG: Typed Arrays not supported 
SCRIPT438: Object doesn't support property or method 'RunSuites' 
index.html, line 116 character 5

If I use the debugger to skip the first error so base.js loads, it kind-of 
runs, but generates a lot of errors due to 'defineProperty'. Box2dWeb, mandreel 
and pdfjs fail without reporting any error.

It seems the problem is related to IE9 Document Mode. If the mode is =IE9 then 
all works and you should not see those errors. If - as it happens right now - 
the mode is IE7, you get errors and the benchmark doesn't run.
We are investigating on this, it doesn't seem just a matter of adding tags to 
the html (which we added today with mixed results).

Anyhow, please do not provide a full shim for gb-emu if you do provide a 
fallback for typed arrays. Legacy arrays should work for gb-emu, as it was 
designed for legacy js array support in addition to typed arrays (Math logic 
should hold true for both kinds, although Opera 11.6X on mac shows opera has 
typed array math bugs).
