Manuel López-Ibáñez <manu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu.org --- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2012-05-13 22:46:42 UTC --- printf warnings are handled in the FE, so we would need constant-propagation in the FE. Clang implements it, so I know it is possible. However, no current contributor to GCC has enough time and interest to implement it, so unless some new contributors appear, don't expect this anytime soon.
