Author	SHA1	Message	Date
Roberto Ierusalimschy	6eb53b7526	Details Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.	5 years ago
Roberto Ierusalimschy	40d8832ee0	Simplification in the call to 'constfolding'	5 years ago
Roberto Ierusalimschy	d6af81084d	New kind of expression VKSTR 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).	5 years ago
Roberto Ierusalimschy	758c1ef445	Unification of size representation in OP_NEWTABLE and OP_SETLIST 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).	5 years ago
Roberto Ierusalimschy	1fb4d53925	OP_NEWTABLE keeps exact size of arrays 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.)	5 years ago
Roberto Ierusalimschy	f6aab3ec1f	First implementation of constant propagation Local constant variables initialized with compile-time constants are optimized away from the code.	5 years ago
Roberto Ierusalimschy	54f7b46c1e	New implementation for constants 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.	5 years ago
Roberto Ierusalimschy	8eca21c2e8	First take on constant propagation	5 years ago
Roberto Ierusalimschy	a006514ea1	Big revamp in the implmentation of labels/gotos 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.	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	03c6a05ec8	no more nil-in-table	7 years ago
Roberto Ierusalimschy	6486762463	missing LUAI_FUNC in prototype for 'luaK_patchgoto'	7 years ago
Roberto Ierusalimschy	4a1612ff9b	new experimental syntax using reserved word 'undef'	7 years ago
Roberto Ierusalimschy	ab07005568	new auxiliary function 'luaK_isKint' + removal of 'luaK_needclose', which was not being used anywhere.	7 years ago
Roberto Ierusalimschy	10b8c99bbb	small peephole optimizations	7 years ago
Roberto Ierusalimschy	a1ef58b3a5	eplicit 1-bit opcode operand 'k'	7 years ago
Roberto Ierusalimschy	722bdbe17d	no more 'getBMode'-'getCMode' (imprecise + we will need more space for op mode) + better control of op modes	7 years ago
Roberto Ierusalimschy	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)	7 years ago
Roberto Ierusalimschy	6a98aa0bb0	new opcode LOADI (for loading immediate integers)	8 years ago
Roberto Ierusalimschy	1f259be52a	'getcode' -> 'getinstruction'	9 years ago
Roberto Ierusalimschy	1ea2d20f74	first implementation of '<<', '>>', and '~' (bitwise not)	11 years ago
Roberto Ierusalimschy	c0edab0f6d	first implementation of bitwise operators '&' (band), '\|' (bor), and '~' (bxor)	11 years ago
Roberto Ierusalimschy	a948054a19	new order for binary operations (grouping them by type of result)	11 years ago
Roberto Ierusalimschy	a2f5c28a80	new operation '//' (integer division)	12 years ago
Roberto Ierusalimschy	5951c79ae1	default increment for 'for' loop is an integer (1, not 1.0)	12 years ago
Roberto Ierusalimschy	ca458f1f52	'luaK_goiffalse' exported	13 years ago
Roberto Ierusalimschy	427ee519db	new instruction OP_LOADKX (to replace OP_LOADK with extra argument)	14 years ago
Roberto Ierusalimschy	dd547c55c8	new scheme to close upvalues in 'break'; jump instructions may do the close, avoiding the need for a OP_CLOSE instruction	14 years ago
