Roberto Ierusalimschy 80bd4a8940 correction on xoshiro256** algorithm 
(should use state[1] instead of state[0] for output)

Roberto Ierusalimschy 3e7415e846 reorganization of '#if's for sellecting a type for 'Rand64' + 
comments
 2018-05-04 17:01:45 -03:00
Roberto Ierusalimschy e64e20ac81 minimizing the code ran by 'vmfetch' + no more 'vra' 
(the code is simpler without 'vra' and conversion is a no-op)
 2018-05-02 15:17:59 -03:00
Roberto Ierusalimschy deb807837c 'luaO_pushvfstring' does not need to reallocate stack 
(less error cases in the API)

Roberto Ierusalimschy b8a04658b2 PRNG changed from 'xoroshiro128+' to 'xoshiro256**' + "I' renamed 'Rand64' 
+ implementation can use integer types larger than 64 (or 32) bits
 2018-04-06 12:41:29 -03:00
Roberto Ierusalimschy b44787652b using 'xoroshiro128+' for PRNG 
(plus a rotate at the final result to have better lower bits)
 2018-04-04 13:12:53 -03:00

(better statistical properties)
 2018-03-26 16:48:46 -03:00
Roberto Ierusalimschy c5e3b2f814 in random/'project', remove the special case for "small" intervals; 
it is slower than the general case.

('rl_readline_name' and 'rl_inhibit_completion')
 2018-03-16 11:23:08 -03:00

(so it does not work when inside a block)
 2018-03-16 11:22:09 -03:00
Roberto Ierusalimschy 7b0b6b3b39 cannot use 'defined' inside a macro +
