Hi,
I'm working on a lua disassembler. I think I have found 2 mistake in comments of OpCode.
In 5.2 OP_JMP be used instead of OP_CLOSE. But the comment says in line 199 of lua-5.2.3/src/lopcodes.h:
OP_JMP,/* A sBx pc+=sBx; if (A) close all upvalues >= R(A) + 1 */
I think it is wrong, it should be:
OP_JMP,/* A sBx pc+=sBx; if (A) close all upvalues >= R(A - 1) */
See lua-5.2/src/lvm.c line 504:
if (a > 0) luaF_close(L, ci->u.l.base + a - 1);
And the comment says in line 207 of lua-5.1.5/src/lopcodes.h:
OP_VARARG/* A B R(A), R(A+1), ..., R(A+B-1) = vararg */
That should be:
OP_VARARG/* A B R(A), R(A+1), ..., R(A+B-2) = vararg */
That has been corrected in lua-5.2
