Roberto Ierusalimschy
4676f6599e new macros 'isOT'/'isIT'

'isOT' instructions)
 2017-12-22 12:16:46 -02:00
Roberto Ierusalimschy

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
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.)

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
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
cb3d5dce30 opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys,

Roberto Ierusalimschy
4758113043 change in opcode OP_LOADNIL: B is used as a counter instead of a 
register. (Avoids an assignment to R(B), not present in any other
instruction.)
 2011-04-19 13:22:13 -03:00
Roberto Ierusalimschy
