Context: _mesa_add_parameter is sometimes[0] called with a NULL name as a mean of an unnamed parameter. Allowing NULL pointer as a name means that it must be NULL checked each access. So far it isn't always[1] true. Parameter name is only used for debug purpose (printf) and to lookup the index/location of the program by the application. Conclusion, there is no valid reason to use a NULL pointer instead of an empty string. So it was decided to use an empty string which avoid all issues related to NULL pointer [0]: texture gather offsets glsl opcode and st_init_atifs_prog [1]: at least shader cache, st_nir_lookup_parameter_index and some printfs Issue found by piglit 'texturegatheroffsets' tests on Nouveau v4: new patch based on Nicolai/Timothy/ilia discussion Signed-off-by: Gregory Hainaut <gregory.hainaut@gmail.com> Reviewed-by: Timothy Arceri <tarceri@itsqueeze.com> |
