Roberto Ierusalimschy 49dae52d08 correct way to check stack space for vararg functions 2018-02-17 17:20:00 -02:00
Roberto Ierusalimschy 104d249ffb in return hook, 'top' must be corrected only if smaller than 'ci->top'. 
(It may be larger when returning multiple values, and then it must
be larger to preserve that stack slice.)
 2018-02-17 16:22:00 -02:00

(avoids test for vararg function in all function calls)
 2018-02-07 13:18:04 -02:00
Roberto Ierusalimschy 73d797ce7e detail 
(order of 'OT' and 'IT' bits corresponds with macro 'opmode')
 2018-02-07 13:04:41 -02:00

(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)
 2018-01-28 10:08:04 -02:00
Roberto Ierusalimschy 6710a2b0ef detail (comment) 2018-01-28 10:07:53 -02:00

Roberto Ierusalimschy 28f215ecf8 comments 2018-01-18 14:24:31 -02:00
Roberto Ierusalimschy d2fb34ac88 'OP_TAILCALL' calling C functions finishes the call and returns 
(instead of waiting for following 'OP_RETURN')
 2018-01-14 15:27:50 -02:00

Roberto Ierusalimschy 4676f6599e new macros 'isOT'/'isIT' 
(plus exchanged parameters of OP_VARARG to make it similar to other
'isOT' instructions)
 2017-12-22 12:16:46 -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
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 3153a41e33 no need to save 'pc' in case of allocation errors 
(allocation errors do not call message handlers)
 2017-12-19 14:18:04 -02:00

 2017-12-18 13:44:44 -02:00
Roberto Ierusalimschy 7024f49c42 default now is compiling without compatibility options + smaller 
stack size in debug mode (clang uses still more stack space when
debugging).
 2017-12-18 11:01:49 -02:00
Roberto Ierusalimschy 2f6f6abeba 'rehash' -> 'tablerehash' 
(to avoid name colisions when compiling Lua as a single file)

in an inconsistent state.
 2017-12-13 16:35:03 -02:00
Roberto Ierusalimschy 86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands 
because, too often, masks in bitwise operations are integers larger
than one byte.)
 2017-12-13 16:32:09 -02:00
Roberto Ierusalimschy 36cf8f3a3c Code should not change the stack level after the initialization of a 
string buffer.
 2017-12-13 10:51:42 -02:00
Roberto Ierusalimschy 725c15a4ca when shrinking stack, always shrinks the CI list. 
(Stack overflow is not corelated to CI overflow anymore.)
 2017-12-12 09:57:30 -02:00
Roberto Ierusalimschy b077b20206 back to reallocation when resizing the string table. 
(Not a good idea to explicitly allocate new memory when shrinking
something.)
 2017-12-12 09:52:35 -02:00
Roberto Ierusalimschy 3cf340f676 allows memory-allocation errors when shrinking blocks 2017-12-11 16:55:31 -02:00
Roberto Ierusalimschy 7ad20af2cf more freedom in handling memory-allocation errors (not all allocations 
automatically raise an error), which allows fixing a bug when resizing
a table.
 2017-12-11 16:53:53 -02:00
Roberto Ierusalimschy bfb88e99e9 'luaD_growstack' cannot raise any errors when 'raiseerror' is 
false (+ some comments)
 2017-12-11 10:43:40 -02:00
Roberto Ierusalimschy c5ebed7399 'luaM_shrinkvector' raises an error if it cannot shrink the block 
(several parts of Lua use array size in protos as proxies for
number of valid elements)
 2017-12-11 10:27:48 -02:00
Roberto Ierusalimschy e663a24ab0 more freedom in handling memory-allocation errors (not all allocations 
automatically raise an error), which allows fixing a bug when resizing
a table.
 2017-12-08 15:28:25 -02:00

Roberto Ierusalimschy cc01d46247 new test function 'T.allocount' to restrict number of allocations 
before a memory-allocation error
 2017-12-07 16:51:39 -02:00
Roberto Ierusalimschy 9fa1baf6de opcodes for order and shift can use several metamethods, 
so it is better to use a generic description + metamethod names
in some error messages shown without '__' prefix
 2017-12-07 13:44:10 -02:00
Roberto Ierusalimschy 49dfaf7447 avoid using one function for different tasks (malloc, free, etc.) 2017-12-06 16:36:31 -02:00
Roberto Ierusalimschy 348fa1ca56 bug: 'lua_pushcclosure' should not call the garbage collector when

 2017-12-06 16:20:28 -02:00
Roberto Ierusalimschy ae11e37e53 bug: 'lua_pushcclosure' should not call the GC when 'n' is zero 2017-12-06 16:08:03 -02:00
Roberto Ierusalimschy c7ee7fe026 new opcodes OP_SHLI/OP_SHRI 2017-12-04 15:41:30 -02:00
Roberto Ierusalimschy 421e459684 'luaS_resize' can raise memory errors 2017-12-01 15:38:49 -02:00
Roberto Ierusalimschy 9d28b40152 rehashes string table always allocating a new array instead of 
reallocating old one. (Avoids problems if reallocation to a small
size fails.)
 2017-12-01 14:40:29 -02:00
Roberto Ierusalimschy e0bece77d6 detail 2017-12-01 13:44:51 -02:00
Roberto Ierusalimschy d0356d5f15 another value for LUAI_MAXCCALLS (must think more about that) 2017-12-01 13:08:14 -02:00

Roberto Ierusalimschy 36aecd4548 order opcodes cannot use 'K' operands 2017-11-28 13:26:15 -02:00
Roberto Ierusalimschy 1a5e8c1014 conditional jumps unified in label "condjump' + new variable 'vra' 
to avoid excessive use of macro 's2v'
 2017-11-28 12:51:00 -02:00
Roberto Ierusalimschy ff5fe51044 using register 'k' for conditions in tests (we only need one bit there) 2017-11-28 10:58:18 -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 39f26b1480 more information from 'T.stacklevel' 2017-11-23 13:38:42 -02:00
Roberto Ierusalimschy 3c230cc825 using 'A' for register instead of 'B' in relational opcodes 
('R(A)' is already created by default for all instructions.)
 2017-11-22 17:15:44 -02:00
Roberto Ierusalimschy 41f2936d8f new opcode 'OP_EQI' for equality with immediate numbers 2017-11-22 16:41:20 -02:00
