* local variables may appear inside blocks in main code.Roberto Ierusalimschy1995-10-261-3/+1

* functions now may be declared with any "var" as a name;Roberto Ierusalimschy1995-10-261-64/+60
| | | | | therefore they do not have a "baptism" name. Changes in debug API to acomodate that.
* new syntax for function declarations: "function a.x () ... "Roberto Ierusalimschy1995-10-251-19/+16
| | | | | new semantics for function declarations: function f () is valid only at run-time.
* new method to keep debug line information: current line is stored on theRoberto Ierusalimschy1995-10-251-89/+125
| | | | | Lua stack, just below (new) base, with tag LUA_T_LINE. SETLINE opcodes are generated by lex.
* new style for debug information about functions: no more SETFUNCTIONRoberto Ierusalimschy1995-10-171-22/+13
| | | | | | | | 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.
* Garbage collection of functions + header structure for functionsRoberto Ierusalimschy1995-10-041-13/+18

* syntax for {...;...} is more flexible now.Roberto Ierusalimschy1995-06-081-10/+21

* because lua_error does a longjmp, there is no need to a variableRoberto Ierusalimschy1994-11-091-69/+36

* Alteracao para retirar codificacao de NOP's, substituindoWaldemar Celes1994-04-131-76/+112
| | | | | | | | pela utilizacao de "union" com "chars" para codificar Word e float. Observa-se que foram realizados testes antes da alteracao e constatou-se que do bytecode anteriormente gerado, NOP representava de 10 a 13% do total de bytes do codigo. Esta percentagem chegava ate' a 20% na caso de descricao de metafile utilizando Lua.
