Author	SHA1	Message	Date
Roberto Ierusalimschy	26be27459b	Negation in constant folding of '>>' may overflow	2 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	0ddc0f47bd	Several details about 5.4.0 rc1 Corrected several small details: added 'const', adjusts in tabs x spaces, removed unused #includes and #defines, misspellings, etc.	5 years ago
Roberto Ierusalimschy	d30569c064	Using an enumeration for float->integer coercion modes	5 years ago
Roberto Ierusalimschy	5e76a4fd31	New macros for arithmetic/bitwise operations in 'luaV_execute' The repetitive code of the arithmetic and bitwise operators in the main iterpreter loop was moved to appropriate macros. (As a detail, the function 'luaV_div' was renamed 'luaV_idiv', as it does an "integer division" (floor division).	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	6e600695f8	field 'sizearray' in struct 'Table' changed to 'alimit', which can be used as a hint for '#t'	6 years ago
Roberto Ierusalimschy	9243c414d9	first version of empty entries in tables (so that, in the future, tables can contain regular nil entries)	7 years ago

Roberto Ierusalimschy	26679ea35b	new function 'luaV_flttointeger' to convert floats to integers (without string coercions) + string operands to bitwise operations handled by string metamethods	7 years ago
Roberto Ierusalimschy	4dff277255	coercion string->number in arithmetic operations moved to string library	7 years ago

Roberto Ierusalimschy	dad85e4131	macro 'setobj2t' may not be an expression	8 years ago
Roberto Ierusalimschy	7647d5d13d	revamp of fast track for table access (table set uses the same macros as table get + new macro for integer keys)	8 years ago
Roberto Ierusalimschy	2a235312f0	detail (removing spaces at end of lines)	8 years ago
Roberto Ierusalimschy	1a44e82200	'luaV_fastget' only treats the real fast case (table with a non-nil value at given key, so that it does not need to check metamethods)	9 years ago
Roberto Ierusalimschy	b91bc93fd3	'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' is not needed in the fast track (as it does not create new entries)	9 years ago
Roberto Ierusalimschy	8f25d08637	'invalidateTMcache' not needed in all 'settable' uses	9 years ago
Roberto Ierusalimschy	3b795541c4	fast track for 'settable'	9 years ago
Roberto Ierusalimschy	e247c3ada3	implementation of fast track for gettable operations	9 years ago
Roberto Ierusalimschy	81245b1ad5	'numisinteger' (for table keys) replaced by 'luaV_tointeger' (old 'tointeger_aux'), which can do the same job.	10 years ago
