Summary

0007583: Float does not use FloatMathPlugin for bit-consistent float math across platforms

Description

Croquet requires that all float operations be bit-reproducable across platforms, and the FloatMathPlugin was made to ensure this works. However, the squeak image does not currently ensure this. Attached is a file-in from Croquet that puts FloatMathPlugin (which is in the VM but apparently unused) to good use. It is also available in the inbox: Kernel-mtf.527

Additional Information

To test this, load Croquet-Kernel (attached), and ignore the initialization errors. Run the test case CroquetVMTests in Croquet-Kernel-Tests. All the float tests in it will pass after the attached changeset is filed in. There are 3 failing and 2 error test cases when I run this on a clean trunk image, but those are unrelated to this issue

FloatMathPlugin crashes the VM if compiled with gcc optimization
