binary operators use R instead of RK faster + nobody uses RK(B), so B can be smaller (freeing one bit for more opcodes, soon)
Roberto Ierusalimschy2017-09-26 15:14:45 -03:00
80d9b09f35
jumps do not close upvalues (to be faster and simpler); explicit instruction to close upvalues; command 'break' not handled like a 'goto' (to optimize removal of uneeded 'close' instructions)
Roberto Ierusalimschy2017-09-13 16:50:08 -03:00
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)
Roberto Ierusalimschy2017-07-27 10:50:16 -03:00
f96497397a
new type 'StackValue' for stack elements (we may want to put extra info there in the future)
Roberto Ierusalimschy2017-06-29 12:06:44 -03:00

'lineinfo' in prototypes saved as differences instead of absolute values, so that the array can use bytes instead of ints, reducing its size. (A new array 'abslineinfo' is used when line differences do not fit in a byte.)
Roberto Ierusalimschy2017-06-27 08:35:31 -03:00

no more 'DEADKEY'. Table traversals do not need to consider dead keys; if the key is dead, it cannot be given to 'next'. Instead, we now use a 'table' tag without the collectable bit, which makes it a unique tag good enough to reserve space.
Roberto Ierusalimschy2017-06-12 11:21:44 -03:00

in hash nodes, keys are stored in separate pieces to avoid wasting space with alignments
Roberto Ierusalimschy2017-06-09 13:48:44 -03:00

when assigning to a 'TValue', better assign only exact fields, to allow us to put stuff after the 'TValuefields' if needed
Roberto Ierusalimschy2017-06-01 17:24:05 -03:00
72d82a296c
revamping the incremental collector Some simplifications (not counting bytes, couting only slots visited; no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to set parameters in different GC modes
Roberto Ierusalimschy2017-05-26 16:14:29 -03:00
4804bbd9bb
include first standard header files (Some broken compiler has problems with 'signal.h' being included without a definition for 'size_t'.)

bug: Lua crashes when building sequences with more than 2^30 elements. bug: Table length computation overflows for sequences larger than 2^31 elements..

BUG: in 'computesizes', 'twotoi' overflows when a sequence has more than 2^30 elements.

'luaH_getn' must return 'lua_Unsigned' (or 'lua_Integer'), to allow the boundary-search algorithm to use 'maxinteger' when it cannot find a good upper bound.
Roberto Ierusalimschy2017-05-19 09:48:15 -03:00
84910e04e2
better implementation for 'hash_search', without using 'size_t' (simpler to implement and to explain)
Roberto Ierusalimschy2017-05-19 09:47:00 -03:00
de74289049
table field names for dedicated opcodes can be restricted to small strings for slightly faster access
Roberto Ierusalimschy2017-05-18 16:44:19 -03:00
49f7aab62a
'lua_rawlen' returns 'lua_Unsigned' instead of 'size_t'. (Real length of strings and userdata are limited by Lua integers, but table length is hard to compute limiting it to 'size_t'.)
Roberto Ierusalimschy2017-05-18 09:34:58 -03:00

reimplementation of 'luaH_getn', trying to handle numeric limits properly.
Roberto Ierusalimschy2017-05-16 16:07:08 -03:00
6d95de83c6
no more field 'base' in CallInfo (base is always equal to 'func + 1', with old/new vararg implementation)
Roberto Ierusalimschy2017-05-13 10:54:47 -03:00
5c8770f896
back to old-style vararg system (with vararg table collecting extra arguments)
Roberto Ierusalimschy2017-05-13 10:04:33 -03:00
7647d5d13d
revamp of fast track for table access (table set uses the same macros as table get + new macro for integer keys)
Roberto Ierusalimschy2017-05-11 15:57:46 -03:00
7184f6343a
more integer fast tracks (for OP_LT, OP_LE, OP_SETTABLE, and OP_GETTABLE)
Roberto Ierusalimschy2017-05-10 14:32:19 -03:00

'luaV_execute' keeps local copy of program counter and hook mask, to avoid excessive access to globals.
Roberto Ierusalimschy2017-05-05 14:16:11 -03:00
2376eb6347
barrier for prototype's cache (with new gray list 'protogray' to keep prototypes to have their caches visited again) + constant 'MAXMISS'
Roberto Ierusalimschy2017-05-04 10:32:01 -03:00
8634b2a011
added 'cachemiss' field to prototype to avoid wasting time checking hits that fail too often
Roberto Ierusalimschy2017-04-30 17:43:26 -03:00
5ecb31003f
bug: cannot "skip" labels after if-goto before the jump over the 'then' part
Roberto Ierusalimschy2017-04-29 15:09:17 -03:00

opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys, so they can use fast-track table access
Roberto Ierusalimschy2017-04-24 17:26:39 -03:00
2caecf1b3e
type 'L_Umaxalign' replaced by macro 'LUAI_MAXALIGN', which is also added to the auxlib buffer
Roberto Ierusalimschy2017-04-24 15:06:12 -03:00
f399e6705f
ensures that "collectgarbage'step'" in generational mode does a minor collection
Roberto Ierusalimschy2017-04-24 14:52:18 -03:00
69371c4b84
'KGC_NORMAL' -> 'KGC_INC' + emergency GC signalled by flag (instead of mode)
Roberto Ierusalimschy2017-04-24 13:59:26 -03:00
f74b87c3c2
removed initialization of 'GCestimate' (it is initialized during a GC cycle, when it start counting)
Roberto Ierusalimschy2017-04-12 15:56:25 -03:00
16001acb15
small corrections + removal of debugging functions 'count' and 'printgray'.
Roberto Ierusalimschy2017-04-12 15:01:40 -03:00
1a1b2f3d7f
added 'return' to calls to 'luaL_error' (to signal to the compiler that the function cannot continue past that call)
Roberto Ierusalimschy2017-03-14 09:40:44 -03:00
94c1b3a8ee
Handling of LUA_PATH/LUA_CPATH moved back to 'package' library to avoid incompatibilites with previous releases
Roberto Ierusalimschy2017-01-12 15:14:26 -02:00
9f594ca6f5
LUA_PATHSUFFIX -> LUA_VERSUFFIX + LUA_VERSUFFIX used in the definition of LUA_INITVARVERSION, too.

using 'lastfree == NULL' to signal that table is using the dummy node for its hash part + new macro 'allocsizenode'
Roberto Ierusalimschy2016-11-07 10:38:35 -02:00
697593d8d5
bug: When a coroutine tries to resume a non-suspended coroutine, it can do some mess (and break C assertions) before detecting the error.
Roberto Ierusalimschy2016-10-19 10:34:27 -02:00
e2dc807c6e
check whether function is finalizer when finding a name for it + comments + some instructions can call functions in unespected ways (e.g., finalizers)
Roberto Ierusalimschy2016-10-19 10:32:10 -02:00
138d00176c
new flag in 'CallInfo.callstatus' to tell whether function is running as a finalizer
