Please submit a full bug report,

The problem goes away if either of these is done:
- using no optimization
- leaving out -fPIC
- leaving out -fprofile-generate

I can reproduce the ICE with gcc 4.8-20120729 and 4.7-20120728, but not with
4.6-20120727, on sparc64-linux.

Jakub, I presume it's an oversight that the combined tldo_add + store patterns
have a "=r" constraint on the source operand:

(define_insn "*tldo_stb_sp32"
  [(set (mem:QI (plus:SI (unspec:SI [(match_operand:SI 2 "register_operand"
"r")
                     (match_operand 3 "tld_symbolic_operand" "")]
                    UNSPEC_TLSLDO)
             (match_operand:SI 1 "register_operand" "r")))
    (match_operand:QI 0 "register_operand" "=r"))]
  "TARGET_TLS && TARGET_ARCH32"
  "stb\t%0, [%1 + %2], %%tldo_add(%3)"
  [(set_attr "type" "store")])

Obviously.  Please remove the = from all the tldo_st*_sp* patterns.  I bet I've
created them from the tldo_ld* patterns initially by swapping the operands.
