318a9a5859 new opcode 'PREPVARARG' 
(avoids test for vararg function in all function calls)

89110986d7 bug in tailcall of vararg functions 
(when adjusting missing parameters)
 2018-01-28 11:39:52 -02:00
Roberto Ierusalimschy
53979dfe0d calling a vararg function needs to check GC 
(because it creates a new table)

ab0a851db4 'luaD_tryfuncTM' can ensure it does not change the stack 2018-01-10 17:19:27 -02:00

28323aeaa6 by-one error when filling missing arguments in a tail call 2017-12-29 13:44:51 -02:00

8691612f01 when calling a hook, cannot decrease 'ci->top' (to preserve stack 
size if the stack is reallocated)
 2017-12-28 12:17:09 -02:00
Roberto Ierusalimschy
1d5b885437 when running Lua code, there is no need to keep 'L->top' "correct"; 
set it only when needed.
 2017-12-20 12:58:05 -02:00

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
b3f924bc69 'Proto->numparams' does not include vararg parameter 
(one less subtraction when calling functions...)
 2017-12-15 11:07:10 -02:00

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)
 2017-12-11 10:43:40 -02:00

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
Roberto Ierusalimschy
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)

472c560705 no more useful fields in CallInfo 2017-11-03 15:22:54 -02:00

54eb35a8aa more fields moved out of 'CallInfo' 2017-11-03 10:12:30 -02:00

ba36180fd7 new API for 'lua_resume' + cleaning the uses of the 'extra' field in 
'CallInfo'
 2017-11-02 09:28:56 -02:00

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)
 2017-05-13 10:04:33 -03:00

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)
 2016-08-01 16:51:24 -03:00

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)
