[Bug target/30153] -fPIC failure

["price at ifa dot hawaii dot edu" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #2 from price at ifa dot hawaii dot edu  2007-05-17 03:19 -------
This is also a problem on my amd64 Gentoo laptop, using gcc version Gentoo
4.1.1-r3.

I searched the binutils Bugzilla, but could not find a bug filed for this
problem.

Because the problem disappears when optimisation is turned on, the following
line from the docs for gcc caught my eye: "GCC does not inline any functions
when not optimizing unless you specify the `always_inline' attribute for the
function".  So I tried:

price@neverland:/home/price/test>cat static_inline.c 
static void foo (void) __attribute__((always_inline));
static inline void foo (void) { }
void baz (void (*f) (void));
void bar (void) { baz (foo); }
price@neverland:/home/price/test>gcc -O0 -g -c -fPIC static_inline.c
price@neverland:/home/price/test>gcc -shared -o static_inline.so
static_inline.o 
/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/../../../../x86_64-pc-linux-gnu/bin/ld:
static_inline.o: relocation R_X86_64_PC32 against `foo' can not be used when

Should I take this bug over to binutils?
