Bug ID: 84312
Summary: Variadic function without named argument not inlined
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: denis.campredon at gmail dot com
Target Milestone: ---
--------------------------------------
int a;
static inline void f2 (...) {a++;}
void f1 (void) { f2 (0); }
--------------------------------------
g++ with optimisations enabled inlines f2 only when f2 is empty or when it is
called with 0 arguments.
When compiled with -Winline the code above produces the following warning
which is I think wrong :
----------------------------------
main.cpp: In function 'void f1()':
main.cpp:3:20: warning: inlining failed in call to 'void f2(...)': mismatched
arguments [-Winline]
static inline void f2 (...) {a++;}
^~
main.cpp:4:21: note: called from here
void f1 (void) { f2 (0); }
~~~^~~
