Subject: -fpic on ppc with SVR4 ABI

Hi,

When I tried to compile glibc for powerpc using egcs, I got

vfscanf.c: In function `_IO_vfscanf':
vfscanf.c:1166: internal error--unrecognizable insn:
(insn 26472 516 506 (set (reg:SI 8 r8)
        (unspec[ 
                (symbol_ref:SI ("@__ctype_b"))
                (mem:SI (plus:SI (reg:SI 31 r31)
                        (const_int 128)))
            ]  8)) -1 (nil)
    (nil))

when making stdio-common/vfscanf.os with -fpic. -fPIC is fine.
I was wondering if anyone had tried to use egcs to build shared
libraries on powerpc with -fpic and SVR4 ABI.

BTW, I cannot find a small test case. The one I got is several
hundred lines.

Thanks.
