System: SunOS bombur.uio.no 5.8 Generic_108528-03 sun4u sparc SUNW,Ultra-5_10
Architecture: sun4
host: sparc-sun-solaris2.8
build: sparc-sun-solaris2.8
target: sparc-sun-solaris2.8
configured with: ./configure --quiet --prefix=/usit/bombur/hbf --program-suffix=-3.0
>Description:
`-O3 -Wunreachable-code' gives a spurious `will never be executed'
warning. It is misplaced as well; the warning it refers to
function `c' - at line 6 which ends function `b'.
>How-To-Repeat:
bash$ cat a.c
void a(void);
void b(void)
{
a();
} /* line 6 */
void c(int i)
{
if (i)
b();
}
bash$ ./xgcc -B./ -O3 -Wunreachable-code -S a.c
a.c: In function `c':
a.c:6: warning: will never be executed
