1995-10-26 12:21:56 -02:00
Roberto Ierusalimschy
39b071f7b1

at run-time.
1995-10-25 12:33:25 -02:00

9efc257d9d
new method to keep debug line information: current line is stored on the

...
opcodes. When a function is called, its entry in the stack is marked with
LUA_T_(C)MARK, so function 'luaD_stackedfunction' can find it if
needed.
Functions now have their file names in the headers, so there is no need
of 'addfile' and the like.
