The reason for that is to support splitting of TImode to 4 SImode pieces, addressable at off+0, off+4, off+8 and off+12.

It's possible that this is the same as bug #42949, but I'm not qualified to judge. I'm sorry I didn't try gcc-snapshot, but I used paer.d.o, the developer machine, to diagnose and I couldn't install it myself.

  2. Bootstrap and regression test with that change plus the fix in (4) show no regressions, and cure the testcase.
  3. See ycode==PLUS checks in offsettable_address_addr_space_p. (2) and (3) together is why we have a problem, since the insn constraints don't cover all possibilities allowed by the insn predicate.
  4. The output is " error: insn does not satisfy its constraints:" and "internal compiler error: in reload_cse_simplify_operands, at postreload.c:411".

See for instructions. my review here We have a mass rebuild of all our packages coming up, does this issue need to be fixed before that ?

The problem is that reload uses the mem for the pseudo without any concern for insn constraints. (Well, not entirely, but gen_reload in this case just uses gen_move_insn.)

It's encouraged to use GCC 4.6 available and default since r8b, though. http://gcc.gnu.org/ml/gcc-patches/2004-08/msg00022.html Geoff patched four insns, one of which, movtf_internal, has since had "o<>" replaced with "Y". lda : 1), _colFactor(layout == ROW_MAJOR ? 1 : lda) {} inline int operator()(int i, int j) { return i * _rowFactor + j * _colFactor; } private: int _rowFactor; int Ah, no, that patch was for find_moveable_pseudos which we don't have on 4.7.

Nothing unusual in that, but gcc also knows it has an equiv mem location.

Still, something is very fishy with reg_equiv_init to have it point at the insn where the pseudo dies. Back to list Status: Assigned Owner: [email protected] Cc: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] Type-Defect I think this is more or less just luck of the draw, so the same thing could happen on mainline with a slightly different test case. Obviously tightening the predicate would work, but as I said in comment #2 the insn is good.

Is this something we have to worry about ? It can and should generate stw 6,32760(19); stw 7,32764(19). 2) The failing constraint is "o<>", specifically "o" so offsettable_memref_p is involved. I'm putting [email protected] in Cc:, perhaps they have a clue. We are very sorry.

Simplified command line (via `ndk-build V=1`, 'APP_OPTIM := release' in Application.mk, executed from source dir. So, why don't we simply use "m" in movdi_internal32 in place of "o<>"?
