Comment 15 for bug 635199

I still think it would be reasonable to hard-code the results for float alignment requirements on ARM.

On all ARM floating-point architecture versions, float and double must be size-aligned. I don't think there has ever been any exception to this rule, nor is any exception likely in the forseeable future IIUC. If the alignment requirements are relaxed someday, the hard-coded results may be suboptimal, but the package should still work.
