Roberto Ierusalimschy c5482468fd baby steps to remove 'CallInfo': keeping 'L->func' correct 2017-10-31 15:54:35 -02:00
Roberto Ierusalimschy 6d998055c8 no more reference 'memerrmsg' + new reference to "n"
(both can be retrieved by 'luaS_newliteral' without creating anything,
because they are fixed, but "n" deserves fast access while 'memerrmsg'
does not)
2017-07-27 10:50:16 -03:00
Roberto Ierusalimschy f96497397a new type 'StackValue' for stack elements
(we may want to put extra info there in the future)

with old/new vararg implementation)
2017-05-13 10:54:47 -03:00
Roberto Ierusalimschy 5c8770f896 back to old-style vararg system (with vararg table collecting extra
arguments)
2017-05-13 10:04:33 -03:00
Roberto Ierusalimschy 24f6e236a3 'moveresults' and 'luaD_poscall' moved up in the file 2016-12-13 13:52:21 -02:00
Roberto Ierusalimschy 8edbf57fb8 detail (ANSI C does not accept empty arguments to macros) 2016-09-20 13:37:45 -03:00
Roberto Ierusalimschy 7fe1a4cff3 cleaner and more correct code for 'luaD_shrinkstack' (the old
test "inuse <= LUAI_MAXSTACK" for stack overflow is not correct,
as the real maximum usable size is "LUAI_MAXSTACK - EXTRA_STACK")
2016-09-08 13:36:26 -03:00
Roberto Ierusalimschy aeb4c6fff1 comments + removed unused variable 2016-09-05 15:53:02 -03:00
Roberto Ierusalimschy e4a9e6fcca do not eliminate varargs from functions that do not use varargs
(confuses the debug lib and gains very little in performance)
2016-08-01 16:51:24 -03:00
Roberto Ierusalimschy 9de2bb0d62 bug: When a coroutine tries to resume a non-suspended coroutine,
it coud do some mess (and break C assertions) before detecting the error.
Now it tests for those errors before anything else.

function
2015-11-02 16:48:49 -02:00
Roberto Ierusalimschy 8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used

2015-11-02 14:09:30 -02:00
Roberto Ierusalimschy c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters

again)
2015-11-02 12:06:01 -02:00
Roberto Ierusalimschy ffd0d1232d using more "conventional" loops in 'luaD_poscall' (probably a little
more efficient?)
2015-11-02 09:48:59 -02:00
Roberto Ierusalimschy 6707ce6349 function prepares vararg only if it really uses them (chunks

two roles)
2015-10-28 10:06:45 -02:00
Roberto Ierusalimschy 5bdee4f810 small changes to allow 'precall' to spend time preserving 'func'
only when needed (that is, when stack actually changes)
2015-10-21 16:40:47 -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)
2015-09-08 12:41:05 -03:00
Roberto Ierusalimschy dcad08b76d details (use original type when saving variable's value) 2015-06-18 11:19:52 -03:00
Roberto Ierusalimschy d39bb51faa bug: interpreter cannot pop activation frame before calling return
hook (as it may want to access local variables active by the end
of the function)
2015-05-22 14:48:19 -03:00
Roberto Ierusalimschy 484bf14a6b calls to 'luaC_checkGC' in luaD_precall moved near to 'luaD_checkstack'

Roberto Ierusalimschy a30c66f0fc macro 'luai_apicheck'/'api_check' back with a 'lua_State' parameter
(some people use it)

Roberto Ierusalimschy 9a38c08011 no need to ensure any stack space for panic function + some changes
in 'tryfuncTM' (small simplification)
2014-11-11 15:13:39 -02:00

inside coroutines
2012-10-01 11:05:04 -03:00
