John Benediktsson 0fb0eaa1cf random: simplify using bitwise operations. 2014-02-25 15:59:51 -08:00
Doug Coleman 48562e6e48 random.mersenne-twister: Don't use system-random-generator to initialize
Mersenne Twister. If there is no system random generator, startup can
fail.

John Benediktsson 4f42c72012 specialized-arrays: performed some cleanup.
Specifically,
    •   Created >c-array to be replacement for >T-array.
    •   Created cast-array to be generic replacement for all T-array-cast words.
    •   Created c-array@ to be generic replacement for T-array@ words.
    •   Replaced usages of <T-array> with T <c-array>
    •   Replaced usages of <direct-T-array> with T <c-direct-array>
    •   Replaced usages of >T-array with T >c-array
    •   Replaced usages of T-array-cast with T cast-array
    •   Replaced usages of malloc-T-array with T malloc-array.
    •   Removed malloc-T-array.
    •   Removed T-array-cast.
    •   Removed T-array@.
    •   Removed >T-array.

I also added (but didn't change any code to use):
    •   T c-array-type, returns T-array
    •   T c-array?, returns T-array?
    •   c-array{ T ... }, returns T-array{ ... }

Bootstraps just find on Mac OS X.  Also `load-all test-all` works for me.

Slava Pestov 7f2e2b1777 Specialized array overhaul
- Replace hand-written specialized-arrays.* subvocabularies with new system; instead of USE:ing specialized-arrays.T, do SPECIALIZED-ARRAY: T
- Ditto for specialized-vectors; use SPECIALIZED-VECTOR:
- io.mmap.functor: removed entirely, use <mapped-array> instead
- struct-arrays and struct-vectors have been removed because specialized arrays and vectors subsume them entirely
