Perhaps the + * specification should remain silent on these kind of things so that they + * could be gracefully added later as an extension or as part of the + * standard. + * + * RESOLUTION: Languages, in general, have programs that are not + * well-formed in ways a compiler cannot detect. Portability is only + * ensured for well-formed programs. Detecting recursion is an example of + * this. The language will say a well-formed program may not recurse, but + * compilers are not forced to detect that recursion may happen. + * + * CLOSED: November 29, 2002." + * + * In GLSL 1.10 the behavior of recursion is undefined. Compilers don't have + * to reject shaders (at compile-time or link-time) that contain recursion. + * Instead they could work, or crash, or kill a kitten. + * + * From page 44 (page 50 of the PDF) of the GLSL 1.20 spec: + * + * "Recursion is not allowed, not even statically. Static recursion is + * present if the static function call graph of the program contains + * cycles." + * + * This langauge clears things up a bit, but it still leaves a lot of + * questions unanswered. + * + * - Is the error generated at compile-time or link-time? + * + * - Is it an error to have a recursive function that is never statically + * called by main or any function called directly or indirectly by main? + * Technically speaking, such a function is not in the "static function + * call graph of the program" at all. + * + * \bug + * If a shader has multiple cycles, this algorithm may erroneously complain + * about functions that aren't in any cycle, but are in the part of the call + * tree that connects them. For example, if the call graph consists of a + * cycle between A and B, and a cycle between D and E, and B also calls C + * which calls D, then this algorithm will report C as a function which "has + * static recursion" even though it is not part of any cycle. + * + * A better algorithm for cycle detection that doesn't have this drawback can + * be found here: + * + * http://en.wikipedia.org/wiki/Tarjan%E2%80%99s_strongly_connected_components_algorithm + * + * \author Ian Romanick <ian.d.romanick@intel.com> + */ +#include "main/core.h" +#include "ir.h" +#include "glsl_parser_extras.h" +#include "linker.h" +#include "program/hash_table.h" + +struct call_node : public exec_node { + class function *func; +}; + +class function { +public: + function(ir_function_signature *sig) + : sig(sig) + { + /* empty */ + } + + + /* Callers of this ralloc-based new need not call delete.
