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 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 4676f6599e new macros 'isOT'/'isIT' 
(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 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.)

Roberto Ierusalimschy 8fbe9e3470 new opcodes with immediate integer operand for all arithmetic operations 2017-10-04 12:49:24 -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 022e4427cf detail (keep OP_LOADK and OP_LOADKX together) 2017-09-15 11:19:06 -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)

Roberto Ierusalimschy 28fdbcf393 added include for 'lprefix.h', for stuff that must be added before
