Name: Kernel.spur-nice.921
Ancestors: Kernel-nice.921, Kernel.spur-topa.920

Kernel-nice.921 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.262

Provide an exact version for #floorLog: for those Number using exact arithmetic
(as proposed in inbox Kernel-nice.721 / 11 December 2012).

Previous version was not exact, otherwise this count would have been zero:
    (-300 to: -1) count: [:n | n ~= ((10 raisedTo: n) floorLog: 10)].

Note that this won't make #log: exact, and could lead to disagreement between the two functions.
However, old behavior compatible with log: is still possible by passing the radix argument asFloat, so this is not a real problem.

Ancestors: Kernel-nice.923, Kernel.spur-nice.922

Kernel-nice.923 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.262

Use an intermediate abstract Float representation (sign, exponent, significand) in order to convert single precision bits to double precision bits rather than attempting the conversion by direct bit manipulations.

This lead to simpler code, because it is like a semantic bit manipulation rather than a raw bit manipulation.

And this also lead to faster code on 32 bits interpreter/COG/Spur VM thanks to avoidance of LargeInteger

(was Kernel-nice.893 / 24 December 2014)

Name: Collections-ul.624
Ancestors: Collections-tfel.623

Various improvements related to Characters and Strings.

Resurrected Character's ClassificationTable
- initialize it based on the actual EncodedCharSet for leadingChar 0 (Unicode)
- added a bit for #isDigit
- added a mask for #isAlphaNumeirc
- use 0 as a tag if the uppercase or lowercase character value is greater than 255
- initialize the table in the postscript (to not infere with #initialize)

Character >> #encodedCharSet assumes than leadingChar 0 means Unicode. This is hardcoded in a few methods, so why not unify it here?

Simpler and faster Character >> #tokenish.

Simpler and faster String >> #withoutLineEndings.

Precalculate the size of the result in Symbol >> #numArgs: to avoid an extra allocation.
