Roberto Ierusalimschy b91bc93fd3 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' 
is not needed in the fast track (as it does not create new
entries)
 2015-09-09 10:44:07 -03:00
Roberto Ierusalimschy 41964648ee long strings are created directly in final position when possible

and then allocate the final string and copy result there)
 2015-09-08 12:41:05 -03:00

converted to integer)
 2015-06-09 12:53:35 -03:00
Roberto Ierusalimschy ed1fe28bb8 When comparing integers with floats, use float as common type when 
possible (i.e., when integer fits in a float without losses); seems
to be more efficient in architectures with native support for used
Lua numbers
 2015-06-02 16:11:24 -03:00

of the function)
 2015-05-22 14:48:19 -03:00
Roberto Ierusalimschy 6dc20ff293 'l <= r' for numbers has its own function, instead of using

Roberto Ierusalimschy 6408bc0b7f new macros 'chgfltvalue'/'chgivalue' (numerical for loop does

 2015-03-02 13:04:52 -03:00
