Re: SIZE_TYPE


Thanks, but when I do so, gcc ICE in build2_stat, at tree.c:3112,
while compiling libgcc2 (__gcc_bcmp) during ivopt pass.
__gcc_bcmp uses a size_t as loop iv.

Here is the failed assert:
  if ((code == MINUS_EXPR || code == PLUS_EXPR || code == MULT_EXPR)
      && arg0 && arg1 && tt && POINTER_TYPE_P (tt))
    gcc_assert (TREE_CODE (arg0) == INTEGER_CST && TREE_CODE (arg1) ==
INTEGER_CST);

while I have
code == PLUS_EXPR,
TREE_CODE (arg0) = SSA_NAME and TREE_CODE(arg1) == NOP_EXPR.


I have no such pb when I define size_t as an unsigned int (HImode),
which is different from my Pmode=PSI mode (32bits).

Any idea where it may come from ? Bad macro definition in my target.h ?

Thanks,
Aurélien
