foo (void)
{
  asm (".pushsection __jump_table,\"aw\"\n\
        .quad %p0\n\
        .popsection" :: "g" (&key));
}
[hjl@gnu-cfl-3 kso-1]$ make CC=gcc
gcc -O2 -fPIC -S foo.c
gcc -O2 -fPIC -c foo.s
foo.c: Assembler messages:

[hjl@gnu-cfl-3 kso-1]$ 

I was expecting

  p -- print raw symbol name.

to work with PIC.
