Bug #: 53716
Summary: Intentional or bug? Inconsistencies in error
diagnostics in function redeclaration involving
stdcall attribute
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: mib.bugzi...@gmail.com
Two questions about diagnostics on templated/non-templated function
redeclarations and the presence of attribute stdcall
Question 1:
// no error for non template function redeclaration, i.e.:
void __attribute((stdcall)) f(int);
void f(int) {;} // compiles fine
// but on x86, g++ 4.6 and later give an error if function is a template --
Why?
template <class T> void __attribute__((stdcall)) f2(int);
template <class T> void f2(int) {;} // error here?
test3.c:2:31: error: new declaration âtemplate<class T> void f2(int)â
test3.c:1:50: error: ambiguates old declaration âtemplate<class T> void
f2(int)â
Question 2:
On x86 (not x64) this test case gets an error when compiled with gcc 4.6.2, but
there is no error when compiled with g++. Is this intentional or should an
error be produced in g++ as well?
% cat test2.c
// no error for non template function redeclaration, i.e.:
void __attribute((stdcall)) f(int);
void f(int a) {;} // compiles fine
gcc -c test2.c
test2.c:3:7: error: conflicting types for âfâ
test2.c:2:30: note: previous declaration of âfâ was here
% g++ -c test2.c
// no error
