8691612f01 when calling a hook, cannot decrease 'ci->top' (to preserve stack 
size if the stack is reallocated)

1d5b885437 when running Lua code, there is no need to keep 'L->top' "correct"; 
set it only when needed.

4dc0be950a new macro 'isLuacode' (to distinguish regular Lua code from 
hooks, where C code can run inside a Lua function).

b3f924bc69 'Proto->numparams' does not include vararg parameter 
(one less subtraction when calling functions...)

725c15a4ca when shrinking stack, always shrinks the CI list. 
(Stack overflow is not corelated to CI overflow anymore.)

bfb88e99e9 'luaD_growstack' cannot raise any errors when 'raiseerror' is 
false (+ some comments)

e663a24ab0 more freedom in handling memory-allocation errors (not all allocations 
automatically raise an error), which allows fixing a bug when resizing
a table.

c766e4103d 'luaV_execute' gets call info as extra argument (it is always 
available on call sites)

194a4f9710 small simplifications in 'luaD_poscall' 2017-11-23 16:29:41 -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

14c3aa12b5 more direct implementation for tail calls. 2017-11-21 12:18:03 -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)

ba36180fd7 new API for 'lua_resume' + cleaning the uses of the 'extra' field in 
'CallInfo'

b9e76be8a6 using 'L->func' when possible 2017-11-01 16:20:48 -02:00

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)

c25380c28d details (using proper version of 'setobj') 2017-05-23 09:50:11 -03:00
Roberto Ierusalimschy
6d95de83c6 no more field 'base' in CallInfo (base is always equal to 'func + 1', 
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)

24f6e236a3 'moveresults' and 'luaD_poscall' moved up in the file 2016-12-13 13:52:21 -02:00

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")

aeb4c6fff1 comments + removed unused variable 2016-09-05 15:53:02 -03:00

e4a9e6fcca do not eliminate varargs from functions that do not use varargs 
(confuses the debug lib and gains very little in performance)

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.

9a5d6aedb7 trying to optimize a little 'luaD_poscall' 2015-11-13 11:24:26 -02:00
Roberto Ierusalimschy
e61ee8a036 in 'luaD_call', use two functions instead of one with fixed boolean 
argument + stack error handling in 'luaD_call' moved to a separated
function
 2015-11-02 16:48:49 -02:00
Roberto Ierusalimschy
8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used 
in critical time pathes, can save a few bytes without the macro)
 2015-11-02 14:09:30 -02:00
Roberto Ierusalimschy
c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters 
only after moving them to final place (avoids checking the stack
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 
are always declared vararg but seldom uses them)

3cdf1d676b details (avoid 'case' inside block + avoid using one variable for 
two roles)
 2015-10-28 10:06:45 -02:00

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

dcad08b76d details (use original type when saving variable's value) 2015-06-18 11:19:52 -03:00

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' 
(which is what can need memory)
 2015-03-30 13:05:23 -03:00
Roberto Ierusalimschy
a30c66f0fc macro 'luai_apicheck'/'api_check' back with a 'lua_State' parameter 
(some people use it)
 2015-03-06 16:49:50 -03:00

9a38c08011 no need to ensure any stack space for panic function + some changes 
in 'tryfuncTM' (small simplification)
