Roberto Ierusalimschy	f356d5acdd	First version of GC counting objects for control Still needs to review generational mode.	2 years ago
Roberto Ierusalimschy	86ec152433	Details correction in macro for hard tests + type in comment	3 years ago
Roberto Ierusalimschy	2ff3471722	Using 'inline' in some functions According to ISO C, "making a function an inline function suggests that calls to the function be as fast as possible." (Not available in C89.)	3 years ago
Roberto Ierusalimschy	59c88f846d	Broadening the use of branch hints More uses of macros 'likely'/'unlikely' (renamed to 'l_likely'/'l_unlikely'), both in range (extended to the libraries) and in scope (extended to hooks, stack growth).	4 years ago
Roberto Ierusalimschy	9d067ab73b	Optimization for 'n^2' Squares are much more common than other exponentiations, and 'n*n' is much more efficient than 'pow'.	4 years ago
Roberto Ierusalimschy	f07de22576	Fixed compiler option -DHARDSTACKTESTS to commit `5aa36e8`	4 years ago
Roberto Ierusalimschy	287b302acb	Revision of stackless implementation - more organized handling of 'nCcalls' - comments - deprecation of 'setcstacklimit'	4 years ago
Roberto Ierusalimschy	6f5bd5072d	Macro LUAI_ASSERT eases turning assertions on	4 years ago
Roberto Ierusalimschy	3747487320	Small correction in assertion	5 years ago
Roberto Ierusalimschy	279c3a6961	A few changes in tests about number of bits in integers - The preprocessor must work with at least 'long', and therefore must do shifts of up to 31 bits correctly. - Whenever possible, use unsigned types in shifts.	6 years ago
Roberto Ierusalimschy	49c42f3615	Some improvements in 'luaconf.h' Added '#if !defined' in some definitions to allow external definitions; more comments; other small changes.	6 years ago
Roberto Ierusalimschy	b14609032c	Avoid the creation of too many strings in 'package' Both when setting a path and searching for a file ('searchpath'), this commit reduces the number of intermediate strings created in Lua. (For setting a path the change is not relevant, because this is done only twice when loading the module. Anyway, it is a nice example of how to use auxlib buffers to manipulate strings in the C API.)	6 years ago
Roberto Ierusalimschy	5ca1075b71	Added field 'srclen' to structure 'lua_Debug' This new field gets the length of 'source' in the same structure. Unlike the other strings in that structure, 'source' can be relatively large, and Lua already has its length readily available.	6 years ago
Roberto Ierusalimschy	0443ad9e28	LUAI_MAXCCALLS renamed LUAI_MAXCSTACK The limit LUAI_MAXCCALLS was renamed LUAI_MAXCSTACK, which better represents its meaning. Moreover, its definition was moved to 'luaconf.h', given its importance now that Lua does not use a "stackless" implementation.	6 years ago
Roberto Ierusalimschy	23e6bac8a0	Keep correct type for immediate operands in comparisons When calling metamethods for things like 'a < 3.0', which generates the opcode OP_LTI, the C register tells that the operand was converted to an integer, so that it can be corrected to float when calling a metamethod. This commit also includes some other stuff: - file 'onelua.c' added to the project - opcode OP_PREPVARARG renamed to OP_VARARGPREP - comparison opcodes rewritten through macros	6 years ago
Roberto Ierusalimschy	ba7da13ec5	Changes in the control of C-stack overflow * unification of the 'nny' and 'nCcalls' counters; * external C functions ('lua_CFunction') count more "slots" in the C stack (to allow for their possible use of buffers) * added a new test script specific for C-stack overflows. (Most of those tests were already present, but concentrating them in a single script easies the task of checking whether 'LUAI_MAXCCALLS' is adequate in a system.)	6 years ago
Roberto Ierusalimschy	9cbf17b0f1	Details (comments)	6 years ago
Roberto Ierusalimschy	5382a22e0e	Corrections in the implementation of '%' for floats. The multiplication (m*b) used to test whether 'm' is non-zero and 'm' and 'b' have different signs can underflow for very small numbers, giving a wrong result. The use of explicit comparisons solves this problem. This commit also adds several new tests for '%' (both for floats and for integers) to exercise more corner cases, such as very large and very small values.	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	06127927ff	new macro 'ispow2'	6 years ago
Roberto Ierusalimschy	34aa0c5bd7	new macros 'likely'/'unlikely' with hints for jump predictions (used only in errors for now)	7 years ago
Roberto Ierusalimschy	e2b15aa21d	janitor work on casts	7 years ago
Roberto Ierusalimschy	f99f3c42ff	comment	7 years ago
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.	7 years ago
Roberto Ierusalimschy	d0356d5f15	another value for LUAI_MAXCCALLS (must think more about that)	7 years ago
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)	7 years ago
Roberto Ierusalimschy	60a7492d24	new type 'ls_byte' for signed bytes	7 years ago
Roberto Ierusalimschy	4bc33d64de	avoid overflows in computation of step size	8 years ago

Roberto Ierusalimschy	d103312661	details (typos in comments)	9 years ago
Roberto Ierusalimschy	5bdee4f810	small changes to allow 'precall' to spend time preserving 'func' only when needed (that is, when stack actually changes)	9 years ago
Roberto Ierusalimschy	9294466234	detail (string cache a bit smaller by default)	9 years ago
Roberto Ierusalimschy	9fae7b6d3f	code for string cache generalized for "associative sets" (compiler will optimize away or inline the extra loops)	9 years ago
Roberto Ierusalimschy	1198d82530	'lua_longassert' defined as an expression (instead of a command)	9 years ago
Roberto Ierusalimschy	b9db9bd0ef	'lua_Number' added to 'L_Umaxalign' union	9 years ago

Roberto Ierusalimschy	a00013c8d0	'point2int' -> 'point2uint' (to reflect its actual result type)	10 years ago
Roberto Ierusalimschy	4ccc4578b3	detail (use 'l_floor' instead of 'l_mathop(floor)')	10 years ago
Roberto Ierusalimschy	c8d6cb0136	macros 'luai_num*' (for float arithmetic operations) moved to llimits.h.	10 years ago
Roberto Ierusalimschy	438a9fcc78	LUAI_MAXSHORTLEN moved from 'luaconf.h' to 'llimits.h' (does not affect the API and is seldom modified)	10 years ago
Roberto Ierusalimschy	5b01cb39b5	larger MINSTRTABSIZE (standard Lua starts with ~230 strings, after oppening the standard libraries)	10 years ago
Roberto Ierusalimschy	a0503305bd	comments	10 years ago
Roberto Ierusalimschy	cdd26700e8	definition for 'MAXUPVAL' moved for a more "private" place and its value and comment corrected to reflect current implementation	10 years ago
Roberto Ierusalimschy	1465edf341	old Visual Studio versions did not support 'noreturn' attribute	10 years ago
Roberto Ierusalimschy	e75c0148c3	comments (references to "ANSI C" changed to "ISO C", which is the international name	10 years ago
Roberto Ierusalimschy	ff6c034330	configurations for types 'lu_mem'/'l_mem'/'Instruction' moved to here (from 'luaconf.h'), as they are not needed by the API and probably will not be changed	10 years ago
Roberto Ierusalimschy	491103708e	'MAXSTACK' -> 'MAXREGS' and moved to 'lcode.c' (there is no reason to change that constant...)	10 years ago
Roberto Ierusalimschy	bdf566a8a3	`name' in comments changed to 'name'	10 years ago
