Roberto Ierusalimschy 2f6f6abeba 'rehash' -> 'tablerehash' 
(to avoid name colisions when compiling Lua as a single file)
 2017-12-18 11:00:57 -02:00
Roberto Ierusalimschy 3064edead2 details (cleaning uses of 'exp1') 2017-12-18 10:33:54 -02:00
Roberto Ierusalimschy f8c1c1469a some cleaning on signed opcode parameters 2017-12-15 16:53:48 -02:00
Roberto Ierusalimschy 4b6928e7f5 (1 << 31) with signed integer has undefined behavior in C 2017-12-15 16:35:22 -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
Roberto Ierusalimschy e001d5aea6 'VRELOCABLE' -> 'VRELOC' 2017-12-14 12:24:02 -02:00
Roberto Ierusalimschy e752d84ed8 bug: memory-allocation error when resizing a table can leave it 
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 7622373033 using explicit tests for allocation overflow whenever possible 2017-12-07 16:59:52 -02:00
Roberto Ierusalimschy 46bc7f2bf7 detail (comment) 2017-12-07 16:53:33 -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 
'n' is zero.
 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 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.)

Roberto Ierusalimschy 4053eae9eb bug: Lua does not check GC when creating error messages 2017-07-27 10:55:38 -03:00
Roberto Ierusalimschy 6d998055c8 no more reference 'memerrmsg' + new reference to "n"
