[Bug web/34443] New: The GCC manual about section variable attribute is incorrect

2007-12-12 Thread fbuihuu at gmail dot com 
Since at least 3.4, the GCC manual says:

 Use the `section' attribute with an _initialized_ definition of a
 _global_ variable, as shown in the example.  GCC issues a warning
 and otherwise ignores the `section' attribute in uninitialized
 variable declarations.

but this doesn't seem correct.

For example compiling the following tiny program:

int foo __attribute__ ((__section__ (".init.data")));

int main(int argc, char **argv)
{
foo = 4;
return 0;
}

produces no warning and the section attribute is not ignored at all:

$ readelf -S a.out | grep -A1 init.data
[24] .init.dataPROGBITS 0060080c  080c
0004    WA   0 0 4

This is with 4.1.2 from fedora, but I guess other GCC give the same result.

I would be nice to have all manuals reflecting this too.

Thanks !
