Author	SHA1	Message	Date
Roberto Ierusalimschy	2376eb6347	barrier for prototype's cache (with new gray list 'protogray' to keep prototypes to have their caches visited again) + constant 'MAXMISS'	8 years ago
Roberto Ierusalimschy	8634b2a011	added 'cachemiss' field to prototype to avoid wasting time checking hits that fail too often	8 years ago
Roberto Ierusalimschy	502a1d1108	new opcodes for table access with constant keys (strings and integers)	8 years ago
Roberto Ierusalimschy	173e41b2eb	new opcode OP_ADDI (for immediate integer operand) (Experimental)	8 years ago
Roberto Ierusalimschy	cb3d5dce30	opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys, so they can use fast-track table access	8 years ago
Roberto Ierusalimschy	6a98aa0bb0	new opcode LOADI (for loading immediate integers)	8 years ago
Roberto Ierusalimschy	a3d36fe283	Upvalues collected like everything else (with mark-sweep) instead of reference count (simpler and better for generational mode)	8 years ago
Roberto Ierusalimschy	2331e1beec	small changes in 'luaC_upvalbarrier'	8 years ago
Roberto Ierusalimschy	fd51651684	new macro 'vmfetch' to help changing code to computed goto's (macro abstracts the code to run before each instruction)	9 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	a272fa66f0	bug: Metatable may access its own dealocated field when it has a self reference in __newindex + some refactoring	9 years ago
Roberto Ierusalimschy	c5112f7b15	details (comments)	9 years ago
Roberto Ierusalimschy	d103312661	details (typos in comments)	9 years ago
Roberto Ierusalimschy	2e8f8a18e4	detail	9 years ago
Roberto Ierusalimschy	9a5d6aedb7	trying to optimize a little 'luaD_poscall'	9 years ago
Roberto Ierusalimschy	04587b6256	macro with empty argument can be seen as macro with no argument; better to avoid that	9 years ago
Roberto Ierusalimschy	ff1289a361	in 'luaD_call', use two functions instead of one with fixed boolean argument	9 years ago
Roberto Ierusalimschy	c5363a1b58	in 'luaD_precall', in vararg functions, complete missing parameters only after moving them to final place (avoids checking the stack again)	9 years ago
Roberto Ierusalimschy	07a2dcacbf	flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations seem to be less frequent than reentries. (So, avoid setting flag on the frequent case.)	9 years ago
Roberto Ierusalimschy	257961c601	OP_SELF can use 'luaV_fastget' specialized for strings, as it is applied only to string keys	9 years ago
Roberto Ierusalimschy	8004ab756f	hook test in 'luaV_execute' reduced to minimum (rest done in 'luaG_traceexec'; no difference in performance for the non-hook case, but keeps 'luaV_execute' a little simpler) + 'base' updates replaced by 'Protect' (which serves this rule)	9 years ago
Roberto Ierusalimschy	f7670781cf	cleaner definition for 'luaC_condGC', using 'pre'/'pos' parameters	9 years ago
Roberto Ierusalimschy	df8b996bcc	'Protect' in table operations is not needed in the fast track + removal of a few dead macros	9 years ago
Roberto Ierusalimschy	ee5edb6b68	macros 'getaddrstr' and 'getstr' unified (they do the same thing)	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	41964648ee	long strings are created directly in final position when possible (instead of using an auxiliar buffer to first create the string and then allocate the final string and copy result there)	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	319ccfefbc	computations in numerical for loop must avoid overflows too	9 years ago
Roberto Ierusalimschy	f01c12c891	detail (cast to avoid mixing types in conditional expression)	10 years ago
Roberto Ierusalimschy	a1415c0d72	bug in order NaN x int (tests must ensure that NaN does not get converted to integer)	10 years ago
Roberto Ierusalimschy	ed1fe28bb8	When comparing integers with floats, use float as common type when possible (i.e., when integer fits in a float without losses); seems to be more efficient in architectures with native support for used Lua numbers	10 years ago
Roberto Ierusalimschy	d39bb51faa	bug: interpreter cannot pop activation frame before calling return hook (as it may want to access local variables active by the end of the function)	10 years ago
Roberto Ierusalimschy	6dc20ff293	'l <= r' for numbers has its own function, instead of using 'not (r < l)' (seems to be slightly more efficient)	10 years ago
Roberto Ierusalimschy	0ec12c1bd1	new semantics for numerical order (following math regardless representation)	10 years ago
Roberto Ierusalimschy	04ba6ea83b	new semantics for equality int-float	10 years ago
Roberto Ierusalimschy	ae76c39712	Bug: suspended '__le' metamethod can give wrong result	10 years ago
Roberto Ierusalimschy	abb2f5511d	detail ('b + base' -> 'base + b' to follow all other similar uses)	10 years ago
Roberto Ierusalimschy	4ba0cb4580	always use macros to operate on lua_Numbers	10 years ago
Roberto Ierusalimschy	6408bc0b7f	new macros 'chgfltvalue'/'chgivalue' (numerical for loop does not need to set the type of its internal variable at each iteration)	10 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
Roberto Ierusalimschy	c8d6cb0136	macros 'luai_num*' (for float arithmetic operations) moved to llimits.h.	10 years ago
Roberto Ierusalimschy	7e2015a46d	size of short strings stored in a single byte, to reduce the size of struct 'TString'	10 years ago
Roberto Ierusalimschy	50e2eb8954	change in macro 'vmcase', avoding code inside it. (Code inside the macro harms tools such as debuggers.)	10 years ago
Roberto Ierusalimschy	2b83711fba	new macro 'nvalue' (to convert an object to a float when we know object is a number)	10 years ago
Roberto Ierusalimschy	049cf14cf9	'x//y' extended to floats + more comments about module and floor division operations	10 years ago
Roberto Ierusalimschy	5d628519d3	simpler definition for 'luaV_tonumber_'	10 years ago
Roberto Ierusalimschy	bde14c3adc	macro to change method of conversion from float to integer (make it use floor intead of requiring an exact integral value)	10 years ago
Roberto Ierusalimschy	28fdbcf393	added include for 'lprefix.h', for stuff that must be added before any other header file	10 years ago
