Subject: [Bug c/19031] [4.0 Regression] #pragma weak handling changes in 4.0.0
Date: Fri, 17 Dec 2004 10:30:00 -0000	[thread overview]
Message-ID: <20041217103004.13552.qmail@sourceware.org> (raw)
In-Reply-To: <20041216104306.19031.pth@suse.de>


------- Additional Comments From aj at gcc dot gnu dot org  2004-12-17 10:30 -------
Further testing showed that this is a fallout from unit-at-a-time: 
 
aj@reger:~/tmp> /opt/gcc/4.0-devel/bin/gcc -c test.c 
aj@reger:~/tmp> nm test.o 
0000000000000000 r bar 
0000000000000000 V foo 
aj@reger:~/tmp> /opt/gcc/4.0-devel/bin/gcc -c test.c -O2 
aj@reger:~/tmp> nm test.o 
                 U bar 
aj@reger:~/tmp> /opt/gcc/4.0-devel/bin/gcc -c test.c -O2 -fno-unit-at-a-time 
aj@reger:~/tmp> nm test.o 
0000000000000000 r bar 
0000000000000000 V foo 
 
The question still remains, what are the symantics?  Do we have to declare 
the variable as extern or not?
