--- Comment #2 from Dodji Seketeli <dodji at gcc dot gnu.org> 2012-05-22 03:50:36 UTC --- Author: dodji Date: Tue May 22 03:50:26 2012 New Revision: 187757 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=187757 Log: PR c++/53322 - -Wunused-local-typedefs is not enabled by Wall or Wunused As the audit trail of this shows, -Wunused-local-typedefs is not turned on by -Wunused after all. Sigh. Now that we have the EnabledBy construct for the *.opt files, it's more precise and concise to use that to make -Wunused-local-typedefs be triggered by -Wunused. I have changed the gcc+.dg/warn/Wunused-local-typedefs.C test case to make it use -Wunused instead of -Wunused-local-typedefs. I had to adjust it to avoid the warnings due to the other -W* options triggered by -Wunused there. While testing the compiler, it turned out that some local typedefs were not being used when the experimental "Concepts" support is turned off, in the libstdc++ test suite. I also had to remove some obvious useless local typedef usage in the fortran front-end. Fixed thus. Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk. gcc/c-family/ PR c++/53322 * c.opt (Wunused-local-typedefs): Use EnabledBy(Wunused). libstdc++-v3/ PR c++/53322 * include/bits/stl_algobase.h (lower_bound) (lexicographical_compare): Do not declare unused local typedefs here when Concepts are turned off. gcc/fortran/ PR c++/53322 * f95-lang.c (gfc_init_builtin_functions): Remove the unused typedef builtin_type. gcc/testsuite/ PR c++/53322 * g++.dg/warn/Wunused-local-typedefs.C: Adjust to use -Wunused instead of -Wunused-local-typedefs.
