> Confirmed. One example (cited in the thread) is:

(In reply to Manuel López-Ibáñez from comment #3)
> This should be warned by -Wsequence-points.
A reduced testcase based on that line still doesn't warn:
$ cat 12411.c && /usr/local/bin/gcc -c -Wall -Wextra -pedantic -Wsequence-point
12411.c
int gen_label_rtx(void);
int get_insns(void);
int emit_label_before(int, int);
int foo(void)
{
int label;
label = emit_label_before(gen_label_rtx(), get_insns());
return label;
}
$
bb-reorder.c no longer contains the code in question though, so at least this
doesn't affect building gcc itself any longer (hopefully)
