Bug ID: 85718
Summary: Incorrect name mangling for va_list on mipsel
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roliver at roku dot com
Target Milestone: ---
--------------------
#include <stdarg.h>
extern void log(char const* fmt, ...);
extern void log(char const* fmt, va_list args);
int main() {
int i = 5;
log("Location of i: %p", &i);
return 0;
}
--------------------
On mipsel, 'log(char const* fmt, va_list args)' is incorrectly mangled to
_Z3logPKcPv rather than _Z3logPKcSt9__va_list which is used on other platforms.
In the above example, code is incorrectly generated to call _Z3logPKcPv on
mipsel whereas the correct code to call _Z3logPKcz is generated on other
platforms. (i.e. the generated code attempts to call the 'va_list'
implementation rather than '...').
