In C++, that's equivalent to `int func(void)`, but in C, that means a function that can take any number of arguments which is rarely what we want. - `missing-prototypes` makes sure we use `static` for file-only internal functions. Non-static functions should have been declared on a prototype file. - Add `no-compound-token-split-by-macro` to the perl cflags, since it throws out a bunch of perl-related warnings that make the CI log unnecessary verbose and hard to read. This seems to happen only with clang 12 and above. When applying those changes, it already uncovered a few warnings, so fix up the code as well (fix prototypes, make the code static, remove shadowed var declaration) GTK header needs to have #pragma warning suppressiong because GTK2 headers will warn on `-Wstrict-prototypes`, and it's included by gui.h and so we can't just turn off the warning in a couple files. closes: #13223 closes: #13226 Signed-off-by: Christian Brabandt Co-authored-by: Yee Cheng Chin diff --git a/ci/config.mk.clang-12.sed b/ci/config.mk.clang-12.sed --- a/ci/config.mk.clang-12.sed +++ b/ci/config.mk.clang-12.sed @@ -1,3 +1,3 @@ # Clang 12 (or Apple clang 13) and later makes a warning '-Wcompound-token-split-by-macro' enable by default. -/^PERL_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=compound-token-split-by-macro/ +/^PERL_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=compound-token-split-by-macro -Wno-compound-token-split-by-macro/ /^RUBY_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=compound-token-split-by-macro/ diff --git a/ci/config.mk.sed b/ci/config.mk.sed --- a/ci/config.mk.sed +++ b/ci/config.mk.sed @@ -1,3 +1,3 @@ -/^CFLAGS[[:blank:]]*=/s/$/ -Wall -Wextra -Wshadow -Werror -Wno-deprecated-declarations/ +/^CFLAGS[[:blank:]]*=/s/$/ -Wall -Wextra -Wshadow -Wstrict-prototypes -Wmissing-prototypes -Werror -Wno-deprecated-declarations/ /^PERL_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=unused-function -Wno-shadow/ -/^RUBY_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=unused-parameter/ +/^RUBY_CFLAGS_EXTRA[[:blank:]]*=/s/$/ -Wno-error=unused-parameter -Wno-strict-prototypes/ diff --git a/src/gui.h b/src/gui.h --- a/src/gui.h +++ b/src/gui.h @@ -22,7 +22,10 @@ # include "gui_gtk_vms.h" # endif // VMS # include +# pragma GCC diagnostic push +# pragma GCC diagnostic ignored "-Wstrict-prototypes" # include +# pragma GCC diagnostic pop #endif #ifdef FEAT_GUI_HAIKU diff --git a/src/if_perl.xs b/src/if_perl.xs --- a/src/if_perl.xs +++ b/src/if_perl.xs @@ -338,7 +338,7 @@ typedef int perl_key; */ static HANDLE hPerlLib = NULL; -static PerlInterpreter* (*perl_alloc)(); +static PerlInterpreter* (*perl_alloc)(void); static void (*perl_construct)(PerlInterpreter*); static void (*perl_destruct)(PerlInterpreter*); static void (*perl_free)(PerlInterpreter*); diff --git a/src/if_py_both.h b/src/if_py_both.h --- a/src/if_py_both.h +++ b/src/if_py_both.h @@ -105,7 +105,7 @@ struct typeobject_wrapper { # define Py_TYPE_GET_TP_METHODS(type) ((PyMethodDef *)PyType_GetSlot(type, Py_tp_methods)) // PyObject_NEW is not part of stable ABI, but PyObject_Malloc/Init are. -PyObject* Vim_PyObject_New(PyTypeObject *type, size_t objsize) +static PyObject* Vim_PyObject_New(PyTypeObject *type, size_t objsize) { PyObject *obj = (PyObject *)PyObject_Malloc(objsize); if (obj == NULL) @@ -168,7 +168,7 @@ PyObject* Vim_PyObject_New(PyTypeObject # define PyIter_Check(obj) (FALSE) # endif -PyTypeObject* AddHeapType(struct typeobject_wrapper* type_object) +static PyTypeObject* AddHeapType(struct typeobject_wrapper* type_object) { PyType_Spec type_spec; type_spec.name = type_object->tp_name; @@ -254,7 +254,7 @@ PyTypeObject* AddHeapType(struct typeobj // Limited API does not provide PyRun_* functions.
