Bug ID: 88674
Summary: GCC thinks that register is a qualifier in function
declaration with no parameters.
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: anders.granlund.0 at gmail dot com
Target Milestone: ---
Test case (prog.c):
void f(register void);
int main()
{
}
Compilation command line:
gcc prog.c -Wall -Wextra -std=c11 -pedantic-errors
Observed behaviour:
The following error message was outputed:
prog.c:1:8: error: 'void' as only parameter may not be qualified
1 | void f(register void);
| ^~~~~~~~~~~~~
Expected behaviour:
No error message outputed.
The program is valid. register is not a type qualifier.
Note:
Clang accepts the program without outputing any error message.
