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.

Roberto Ierusalimschy b08c9079c5 Opcode names moved to a new header file 
The array with the names of the opcodes was moved to a header file
('lopnames.h'), as it is not used by the Lua kernel. Files that need
that array ('luac.c' and 'ltests.c') include the header file to get
a private (static) copy.

Roberto Ierusalimschy b43300c14f change in 'LUAI_DDEC' to allow variables to be static in 'onelua' 
+ change in 'LUAMOD_API' as opening functions do not need to be global

Roberto Ierusalimschy b1379936cf vararg back to '...' (but with another implementation) 
new implementation should have zero overhead for non-vararg functions
 2018-02-09 13:16:06 -02:00
Roberto Ierusalimschy 318a9a5859 new opcode 'PREPVARARG' 
(avoids test for vararg function in all function calls)
 2018-02-07 13:18:04 -02:00
Roberto Ierusalimschy 73d797ce7e detail 
(order of 'OT' and 'IT' bits corresponds with macro 'opmode')
 2018-02-07 13:04:41 -02:00
Roberto Ierusalimschy e2b15aa21d janitor work on casts 2018-01-28 13:13:26 -02:00

(plus exchanged parameters of OP_VARARG to make it similar to other
'isOT' instructions)
 2017-12-22 12:16:46 -02:00
Roberto Ierusalimschy d388c165ef new opcodes 'FORLOOP1'/'FORPREP1' for "basic for" (integer variable 
with increment of 1)
 2017-12-18 15:53:50 -02:00
Roberto Ierusalimschy f8c1c1469a some cleaning on signed opcode parameters 2017-12-15 16:53:48 -02:00
Roberto Ierusalimschy 4b6928e7f5 (1 << 31) with signed integer has undefined behavior in C 2017-12-15 16:35:22 -02:00
Roberto Ierusalimschy 86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands 
because, too often, masks in bitwise operations are integers larger
than one byte.)
 2017-12-13 16:32:09 -02:00

Roberto Ierusalimschy ff5fe51044 using register 'k' for conditions in tests (we only need one bit there) 2017-11-28 10:58:18 -02:00
Roberto Ierusalimschy 093c16b67b new opcodes 'OP_LTI' and 'OP_LEI' 2017-11-27 15:44:31 -02:00
Roberto Ierusalimschy 3c230cc825 using 'A' for register instead of 'B' in relational opcodes 
('R(A)' is already created by default for all instructions.)
 2017-11-22 17:15:44 -02:00

Roberto Ierusalimschy bc1b0733b8 avoid the use of bit 'Bk' ('B' will lose this bit soon) 2017-10-01 16:13:43 -03:00
Roberto Ierusalimschy 722bdbe17d no more 'getBMode'-'getCMode' (imprecise + we will need more space 
for op mode) + better control of op modes
 2017-09-28 13:53:29 -03:00
Roberto Ierusalimschy 00e728af88 binary operators use R instead of RK 
faster + nobody uses RK(B), so B can be smaller (freeing one bit
for more opcodes, soon)
 2017-09-26 15:14:45 -03:00
Roberto Ierusalimschy abb17cf19b new opcode OP_LOADF (load immediate float) 2017-09-19 15:38:14 -03:00

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)
 2017-09-13 16:50:08 -03:00
Roberto Ierusalimschy ac65bab25f jumps in 'for' loops don't need to be signed 2017-08-14 15:33:14 -03:00

Roberto Ierusalimschy 173e41b2eb new opcode OP_ADDI (for immediate integer operand) (Experimental) 2017-04-26 14:46:52 -03:00
Roberto Ierusalimschy cb3d5dce30 opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys, 
so they can use fast-track table access
