Hi,
I have verified that it indeed is a gas bug which prevents the ELF
support in gcc working properly. As you can see, foo.s is
mis-assembled as
00000000 <foo> call 00000002 <foo+2>
with
0000 e8fdffff ffc3 ......
I patched .o file by hand to
00000000 <foo> call 00000001 <foo+1>
with
0000 e8fcffff ffc3 ......
It seems ok. I am not very familiar with gas and don't know hard to
fix this bug.
