Sorry, the commandline I gave is missing the -O. So it should be:
/tmp/gccml/libexec/gcc/i686-pc-linux-gnu/4.1.0/cc1 -fpreprocessed blah.i -quiet
-dumpbase blah.c -march=i386 -auxbase blah -version -o blah.s -O -ftree-pre

Confirmed, this is 4.1 regression.
Before in 4.0, we got:
pretmp.2_11 = x_4 * -1;
But after the patch to fold that to - x_4, we get:
pretmp.2_11 = (int) -x_4;
The problem is that the type for x_4 is gint so we need a NOP_EXPR so we get the correct types (there is
a fold_convert in fold).
