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	2caecf1b3e	type 'L_Umaxalign' replaced by macro 'LUAI_MAXALIGN', which is also added to the auxlib buffer	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	a80cada914	new cache for interning strings	10 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
Roberto Ierusalimschy	325e44d87e	no more "-2" for limits. (Limits should be precise; safety is in the code that handles these limits.)	10 years ago
Roberto Ierusalimschy	54ac253343	detail (no need to define LUAI_USER_ALIGNMENT_T when it is not defined; simpler to define 'L_Umaxalign' directly)	10 years ago
Roberto Ierusalimschy	5bbb4a06a6	removed unused parameter Ä'L' in macro 'api_check' and company	10 years ago
Roberto Ierusalimschy	c94f11d783	'IntPoint' -> 'point2int' + ensure that casted value fits in destination type	11 years ago
Roberto Ierusalimschy	037a70dfea	cast_u2s/cast_s2u renamed l_castS2U/l_castU2S to be configurable from outside (mostly for testing)	11 years ago
Roberto Ierusalimschy	8f961da3db	macros cast_integer/cast_unsigned replaced by cast_u2s/cast_s2u, that should be used only between lua_Integer and lua_Unsigned	11 years ago
Roberto Ierusalimschy	ef789d4161	new global macro 'LUA_MAXUNSIGNED'	11 years ago
Roberto Ierusalimschy	bf06e22b6a	correct definition for 'MAX_SIZE' (using singed integers as the limit, not unsigned ones) + new type 'l_uacInt'	11 years ago
