digitalmars.D - std.math.poly and const

reply dsimcha <dsimcha yahoo.com> writes:
Should the function signature of std.math.poly be (real x, const real[] A),
not (real x, real[] A)?  The D code at the end of the function clearly doesn't
modify A, but I have no idea what the ASM code is doing.  Is this a bug?

Yes, it should be const.

Yes, it should be const.

crc32 module also needs to be updated. Not only it doesn't use const (but should, it allows compile-time crc32 evaluation), but it also uses char[] instead of string! :)
