* Added gcc option '-Wconversion'Roberto Ierusalimschy2024-07-271-1/+1
| | | | | No warnings for standard numerical types. Still pending alternative numerical types.
* New instruction format for SETLIST/NEWTABLERoberto Ierusalimschy2024-06-281-2/+4
| | | | | | New instruction format 'ivABC' (a variant of iABC where parameter vC has 10 bits) allows constructors of up to 1024 elements to be coded without EXTRAARG.
* Some 'unsigned int' changed to 'unsigned'Roberto Ierusalimschy2024-03-221-1/+1
| | | | | 'unsigned int' is too long sometimes. (We already write 'long' instead of 'long int'...)
* Several functions turned 'static'Roberto Ierusalimschy2023-05-221-3/+0
| | | | | Several functions that were already being used only inside their own file have been declared as 'static'.
* DetailsRoberto Ierusalimschy2020-02-271-1/+1
| | | | | Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.
* Simplification in the call to 'constfolding'Roberto Ierusalimschy2019-09-111-2/+10
|
* New kind of expression VKSTRRoberto Ierusalimschy2019-07-171-1/+0
| | | | | | | String literal expressions have their own kind VKSTR, instead of the generic VK. This allows strings to "cross" functions without entering their constant tables (e.g., if they are used only by some nested function).
* Unification of size representation in OP_NEWTABLE and OP_SETLISTRoberto Ierusalimschy2019-07-151-1/+3
| | | | | | Opcodes OP_NEWTABLE and OP_SETLIST use the same representation to store the size of the array part of a table. This new representation can go up to 2^33 (8 + 25 bits).
* OP_NEWTABLE keeps exact size of arraysRoberto Ierusalimschy2019-07-121-0/+1
| | | | | | OP_NEWTABLE is followed by an OP_EXTRAARG, so that it can keep the exact size of the array part of the table to be created. (Functions 'luaO_int2fb'/'luaO_fb2int' were removed.)
* First implementation of constant propagationRoberto Ierusalimschy2019-07-121-0/+1
| | | | | Local constant variables initialized with compile-time constants are optimized away from the code.
* New implementation for constantsRoberto Ierusalimschy2019-07-091-1/+0
| | | | | | | | | VLOCAL expressions keep a reference to their corresponding 'Vardesc', and 'Upvaldesc' (for upvalues) has a field 'ro' (read-only). So, it is easier to check whether a variable is read-only. The decoupling in VLOCAL between 'vidx' ('Vardesc' index) and 'sidx' (stack index) should also help the forthcoming implementation of compile-time constant propagation.
* First take on constant propagationRoberto Ierusalimschy2019-07-011-0/+1
|
* Big revamp in the implmentation of labels/gotosRoberto Ierusalimschy2018-10-291-3/+0
| | | | | | | | Added restriction that, when a label is created, there cannot be another label with the same name visible. That allows backward goto's to be resolved when they are read. Backward goto's get a close if they jump out of the scope of some variable; labels get a close only if previous goto to it jumps out of the scope of some upvalue.
* Removed extra information from RCS keyword stringsRoberto Ierusalimschy2018-08-231-1/+1
| | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.
* no more nil-in-tableRoberto Ierusalimschy2018-04-041-2/+1
|
* missing LUAI_FUNC in prototype for 'luaK_patchgoto'Roberto Ierusalimschy2018-03-191-2/+3

|
* new auxiliary function 'luaK_isKint' + removal of 'luaK_needclose',Roberto Ierusalimschy2017-12-181-2/+2

|
* eplicit 1-bit opcode operand 'k'Roberto Ierusalimschy2017-10-041-2/+6
|
* no more 'getBMode'-'getCMode' (imprecise + we will need more spaceRoberto Ierusalimschy2017-09-281-2/+2
| | | | for op mode) + better control of op modes
* jumps do not close upvalues (to be faster and simpler);Roberto Ierusalimschy2017-09-131-2/+4
| | | | | | explicit instruction to close upvalues; command 'break' not handled like a 'goto' (to optimize removal of uneeded 'close' instructions)
