With gcc-6, foo compiles without error. With gcc-5,
dave@mx3210:~/gnu/gcc/objdir$ gcc -freorder-blocks-and-partition -S -O2 xxx.c
xxx.c:1:0: note: -freorder-blocks-and-partition does not work on this
architecture
void foo (void) { }
^
We have in pa.c (pa_option_override):
/* Disable -freorder-blocks-and-partition as we don't support hot and
cold partitioning. */
if (flag_reorder_blocks_and_partition)
{
inform (input_location,
"-freorder-blocks-and-partition does not work "
"on this architecture");
flag_reorder_blocks_and_partition = 0;
flag_reorder_blocks = 1;
}
