Roberto Ierusalimschy af70905246 no need to check whether libraries and host use the same kernel; 
Lua should work correctly with several copies of the kernel
 2018-06-18 09:08:10 -03:00
Roberto Ierusalimschy b95e466218 new field 'nilvalue' in struct 'global_State' to avoid the use of 
addresses of static variables
 2018-06-15 16:31:22 -03:00
Roberto Ierusalimschy 505fc91222 no more 'luaO_nilobject' to avoid comparison of global variable addresses

Roberto Ierusalimschy 4dc0be950a new macro 'isLuacode' (to distinguish regular Lua code from 
hooks, where C code can run inside a Lua function).
 2017-12-19 14:40:17 -02:00
Roberto Ierusalimschy 196c87c9ce no more 'stackless' implementation; 'luaV_execute' calls itself 
recursively to execute function calls. 'unroll' continues all
executions suspended by an yield (through a long jump)
 2017-11-23 14:41:16 -02:00
Roberto Ierusalimschy 5440b42f43 using 'trap' to stop 'luaV_execute' when necessary (tracing and 
to update its copy of 'base' when the stack is reallocated)

Roberto Ierusalimschy f96497397a new type 'StackValue' for stack elements 
(we may want to put extra info there in the future)
 2017-06-29 12:06:44 -03:00
Roberto Ierusalimschy 72d82a296c revamping the incremental collector 
Some simplifications (not counting bytes, couting only slots visited;
no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to
set parameters in different GC modes
 2017-05-26 16:14:29 -03:00
Roberto Ierusalimschy 2376eb6347 barrier for prototype's cache (with new gray list 'protogray' to keep

of mode)
 2017-04-24 13:59:26 -03:00

Roberto Ierusalimschy 33b366ec32 added counters for total and individual CallInfo entries (to allow 
better syncronization between CallInfo size and stack size)
 2015-11-02 14:01:41 -02:00
Roberto Ierusalimschy 75d5a8924c macro 'addbuff' was using external variable name, instead of using 
its parameter name inside the macro.
 2015-10-20 11:11:05 -02:00
Roberto Ierusalimschy 41964648ee long strings are created directly in final position when possible 
(instead of using an auxiliar buffer to first create the string
and then allocate the final string and copy result there)
